Abstract:
Multiple captures of small mammals (finding >1 animal in a single trap) are often used to infer pair-bonding activity in arvicoline and cricetine rodents. We analyzed data from a 2-year trapping study to determine whether fulvous harvest mice ( Reithrodontomys fulvescens J.A. Allen, 1894) and (or) northern pygmy mice (Baiomys taylori (Thomas, 1887)) travel in mixed-sex mated pairs. A significant majority of multiple capture events (MCEs) in R. fulvescens were mixed-sex, whereas sex composition of pairs in B. taylori did not differ from random. Multiple capture probability was significantly positively related to abundance and unrelated to sex ratio in both species. Multiple captures of B. taylori were more common in winter, suggesting that individuals may associate to huddle for warmth. Masses of singly captured and multiply captured individuals were not significantly different in either species, contraindicating trap bias. Only one co-captured mixed-sex pair was recaptured as a pair (in R. fulvescens) and several animals of both sexes in both species were co-captured with multiple individuals. We concluded that R. fulvescens co-travels with mates for variable lengths of time, but we found no evidence that multiple captures of B. taylori are related to reproductive behavior.

Abstract:
Carbon dioxide (CO<sub>2</sub>) is a primary contributor to global climate change. Efforts to curb climate change include the capture and storage from this carbon, as well as the conversion of carbon gas into clean fuels. Carbon capture and storage (CCS) is a commercially developing technology to capture CO<sub>2</sub> from power generation plants, compress it, and store it in a geologic reservoir. The three main CCS systems (post-combustion capture, pre-combustion capture, and oxyfuel technologies) were compared in terms of carbon capture ability and process flow diagrams were created. From analysis all methods have similar capturing abilities, but oxyfuel technology requires the lowest energy to capture CO<sub>2</sub> and has the lowest CO<sub>2</sub> cost breakeven point. Additionally, other developing carbon capture and utilization methods were discussed, including a gas fermentation process to produce ethanol and direct air carbon capture.

Abstract:
The need to cut CO 2 emission into the atmosphere is pushing scientists and technologists to discover and implement new strategies that may be effective for controlling the CO 2 atmospheric level (and its possible effects on climate change). One option is the capture of CO 2 from power plant flue gases or other industrial processes to avoid it entering the atmosphere. The captured CO 2 can be either disposed in natural fields (geological cavities, spent gas or oil wells, coal beads, aquifers; even oceans have been proposed) or used as a source of carbon in synthetic processes. In this paper, we present the options for CO 2 utilization and make an analysis of possible solutions for the conversion of large volumes of CO 2 by either combining it with H 2 , that must be generated from water, or by directly converting it into fuels by electrolysis in water using solar energy. A CO 2 –H 2 -based economy may address the issue of reducing the environmental burden of energy production, also saving fossil carbon for future generations. The integration of CO 2 capture and utilization with CO 2 capture and storage would result in a more economically and energetically viable practice of CO 2 capture.

Abstract:
The electrochemical production of carbon monoxide (CO) from carbon dioxide (CO2) has conventionally relied on gas-phase CO2 electrolysis with complex upstream capture and downstream gas separation processes. Reactive capture of CO2 – an integrated approach that combines CO2 capture and electrochemical conversion – uses chemisorbed CO2 directly as the feedstock and thereby avoids CO2 purification and associated costs. To date, reactive capture has relied on hydroxide-based capture solutions (e.g. potassium hydroxide (KOH)) suitable for direct air capture (DAC) processes or amines (e.g. monoethanolamine (MEA)) that have been conventionally used for point source capture. However, in hydroxide-based systems that capture CO2 in the form of carbonate, the CO Faradaic efficiency (FE) is limited to 50% due to the interaction between in-situ regenerated CO2 and local hydroxides that reduce CO2 availability at the cathode. Amine-based reactive capture can overcome this selectivity challenge when CO2 is captured in the form of carbamate and bicarbonate; compared to carbonate, these forms of chemisorbed CO2 require less electron-coupled protons to regenerate in-situ CO2, and thus yield more CO2 at the cathode. However, conventional amines are volatile and have poor oxygen tolerance, rendering them inapplicable to oxygen-rich CO2-lean conditions. Here, we report amino acid salt (AAS)-based reactive capture of CO2 that exceeds the CO energy efficiency (EE) achieved in amine- and hydroxide- based systems. The AAS capture solution, potassium glycinate (K-GLY), contains amino functional groups for efficient CO2 capture while offering advantages including oxygen tolerance, low vapor pressure, and low toxicity. We synthesized a nickel single atom (Ni-N/C) catalyst to improve conversion efficiency, optimized the capture solution composition to reduce the electrolysis overpotential at high current densities, and elevated the operating temperature and pressure to increase availability of dissolved in-situ CO2 at the cathode. We achieve CO production with 64% CO FE and a measured full cell voltage of 2.74 V at 50 mA cm-2, resulting in an CO EE of 31% and an energy intensity of 40 GJ tCO-1. The feasibility of the full reactive capture process was demonstrated with both simulated flue gas and direct air input.

Abstract:
Purpose Previous work has asserted that the co-innovation process in the music business is composed of four stages, i.e. co-discovery, co-creation, co-delivery and co-capture. This study aims to re-examine and validate this proposed conceptualisation by gathering and interviewing additional respondents, specifically academics and professional event organisers, who were not formerly involved. By gaining more insight from different stakeholders, this study expects to gain more reliable results regarding the proposed concept derived from the previous study. Design/methodology/approach This study uses the case study method by carrying out qualitative interview data collection from 11 respondents. Narrative analysis is used in examining the findings. Pattern matching is used as the basis of the analysis using the proposed conceptualisation from co-discovery to co-capture of co-innovation as the rival analysis to the empirical findings discovered in this study. This paper also discusses how the validity and reliability of the qualitative analysis carried out are ensured. Findings This study supports the notion that the co-innovation process in the music industry follows the four stages of co-discovery, co-creation, co-delivery and co-capture. The respondents, from different professional backgrounds, interviewed in this study indicated and validated that the proposed framework aligns with their actual practices, expectations and realities, along with their specific roles in the music industry’s ecosystems. Practical implications The results of this study can be used as a reference in developing guidelines or policies for co-innovation practices in the music business, which previous studies have not explored, e.g. focusing only on preconditions for positive collaboration, open license and music for co-creation or discussions that are merely conceptual. Originality/value This study validates the co-innovation process in the music business proposed by the previous works, which integrates the value chain thinking concept within the analysis.

Abstract:
Technologies that can capture CO2 and enable conversion into value-adding chemicals and fuels or stable minerals for sequestration are vital for transitioning towards net zero or even negative greenhouse gas emissions. Conventional approaches for electrochemically converting CO2 have utilized a decoupled approach of first capturing and concentrating CO2, and then using the concentrated CO2 as a feedstock for conventional electrochemical processes. Direct electrochemical reduction of amine-captured CO2 1,2 can potentially offer advantages by removing the need to thermally regenerate the amine capture solution, which can be energy intensive and typically uses thermal energy from nonrenewable sources. In this talk, we share our recent work on the electrochemical reduction of amine-captured CO2 to value-adding products like CO and stable minerals like carbonates. We discuss the influence of the capture environment on the resulting capture solution chemistry, and how to alter the capture solution speciation through electrolyte design. We further consider the detailed CO2 reduction mechanisms in these amine-containing solutions and provide design strategies for increasing the Faradaic efficiency of CO2 reduction vs. the competitive hydrogen evolution reaction (HER), as well as decreasing the overpotential of CO2 reduction.

Abstract:
Electron thermalization in X irradiated liquid CO is truncated by electron capture to form an anion, as it is in liquid N2. The thermalization distance distribution in these two liquids is a modified exponential, rather than the modified Gaussian obtained in liquid hydrocarbons where electron capture does not occur. The density normalized distance parameter bEPd in CO was constant, 2.8 × 10−6 kg/m2, at densities [Formula: see text], but increased somewhat at lower densities, reaching 3.3 × 10−6 kg/m2 at d/dc = 1.4. The thermalization distances in CO are about two thirds those in N2 at the same density. Electrons are captured more readily by CO than by N2.

Abstract:
One of the leading technologies for reducing industrial CO<sub>2</sub> emissions is Carbon Capture and Storage (CCS). Existing publications address the high energy requirements of the capture process, while overlooking the subsequent compression process required for CO<sub>2</sub> transportation which also exhibits intense energetic needs. This work aims to investigate and compare the energy requirements of two alternative methods to the conventional process for pressurising captured CO<sub>2</sub> to 150 bar. After the capture process, CO<sub>2</sub> is typically at near atmospheric pressure, requiring multi-stage compression due to compressor limitations. After each compression stage, cooling is required to maintain the fluid close to the optimal temperature for further compression. The proposed alternative methods utilise the compressed CO<sub>2</sub>, which is in supercritical state (sCO<sub>2</sub>), as working fluid to recover heat that is available among the compression stages. One of the alternative methods uses sCO<sub>2</sub> in an integrated open supercritical Rankine cycle (sRC) at each cooling stage. The other method, apart from the sRC, heats the CO<sub>2</sub>-rich liquid stream before the regeneration column of the capture process at the final compression stage. The compression processes are designed for a CO<sub>2</sub> stream of 2,779 t/d, representing the typical captured CO<sub>2</sub> mass flow from a 400 MW power plant. Results suggest that the case of combining sRC and the CO<sub>2</sub>-rich stream heating is the most energy-efficient among the tested cases, requiring 5.11 MW less than the sRC-only case and 4.31 MW less than the conventional compression case without intercooling.

Abstract:
This thesis is mainly concerned with the study of solvents of relevance for carbon capture and storage (CCS). The current industrial approach relies on amines to capture CO2, however this thesis describes a range of alternative non-amine based solvents, particularly phenols, saturated and unsaturated aliphatic acids, long chain fatty acids, aromatic acids, and β-dicarbonyl compounds (mainly ketones and esters). The CO2 capture capacities of these substrates have been compared with the industrial model substrate (monoethanolamine, MEA). From this study, phenols show 49-90% CO2 capture capacity whereas aromatic phenolic acids such as gallic acid show up to 100% theoretical CO2 capture capacity. Acetylacetone, a β-diketone shows 88% and the rest of the substrates from this and other groups show 50-60% CO2 capture capacity. However, some of the substrates, particularly simple mono and polycarboxylic acids showed negligible CO2 capture capacity, which can be understood on the basis of pKa. Particular attention has been paid to understanding the formation of bicarbonate salts, which would be expected under aqueous conditions. Clear evidence for their formation is provided by 13C NMR studies. The measured CO2 capture capacities of the new substrates have been correlated with pKa values. Those with pKa values between 9-13 have excellent to good CO2 capture capacity whereas others having pKa < 7, have insignificant CO2 capture capacity. The substrates with low pKa capture less volume of CO2 compared to those having high pKa, but release it more easily on heating. The second body of work is a study on the chemistry of MEA and its oxidised derivatives. MEA is currently the industry standard for CO2 capture. Given that power station flue gases contain large amounts of oxygen, and trace metals which may act as oxidation catalysts, understanding the chemistry of oxidised MEA derivatives is of increasing importance. This can have a significant effect on solvent activity and lifetime, which are important aspects of the economic profile of CCS. MEA was oxidised under a variety of conditions, and a complex mixture of products was formed. Many of these have been unambiguously identified by comparison with commercial or synthetic samples. The main oxidation products were then heated at 100°C for prolonged periods of time to mimic conditions in a commercial CCS system. Thermal degradation of MEA oxidation products was clearly observed, and in some cases, could be rationalised on the basis of established organic reactivity.

Abstract:
Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Chemical Engineering, 2009.<br>Includes bibliographical references (leaves 182-185).<br>The objective of this thesis is to evaluate a new carbon dioxide compression technology - shock compression - applied specifically to capture-enabled power plants. Global warming has increased public interest in carbon capture and sequestration technologies (CCS), but these technologies add significant capital and operating cost at present, which creates a significant barrier to adoption. Carbon dioxide compression technology makes up a high proportion of the additional cost required, making it a focal point for engineering efforts to improve the economic feasibility of carbon capture. To this effect, shock compressors have the potential to reduce both operating and capital costs with supporting compression ratios of up to 10:1, requiring less stages and theoretically allowing for the possibility of heat integration with the rest of the plant, allowing waste heat to be recovered from hot interstage compressed carbon dioxide. This thesis first presents a technical context for carbon dioxide compression by providing an overview of capture technologies to build an understanding of the different options being investigated for efficient removal of carbon dioxide from power plant emissions. It then examines conventional compression technologies, and how they have each evolved over time. Sample engineering calculations are performed to model gas streams processed by these conventional compressors. An analysis of shock compression is carried out by first building a background in compressible flow theory, and then using this as a foundation for understanding shock wave theory, especially oblique shocks. The shock compressor design is carefully analyzed using patent information, and a simulation of the physics of the shock compressor is created using equations from the theory section described earlier.<br>(cont.) A heat integration analysis is carried out to compare how conventional compressor technologies compare against the new shock compressor in terms of cooling duty and power recovery when integrated with the carbon dioxide capture unit. Both precombustion IGCC using Selexol and post-combustion MEA configurations are considered and compared. Finally an economic analysis is conducted to determine whether shock compression technology should be attractive to investors and plant managers deciding to support it. Key factors such as market, macroeconomic and technical risk are analyzed for investors, whereas a comparison of capital and operating cost is carried out for plant managers. Relevant risks associated with new compression technologies are also analyzed. It is found that there is no significant operating cost benefit to the shock compressor over the conventional compressor, both costing $3,700/hr for an IGCC plant. Power recovery is simply too low to justify the high power requirements in operating a shock compressor with a 10:1 ratio. The technical claims of the shock compressor (such as projected discharge temperature and pressures) seem reasonable after basic modeling, which shows a higher temperature and pressure than claimed by Ramgen.<br>by Rajat Suri.<br>S.M.

Abstract:
As concerns mount about the rise in atmospheric CO₂ concentrations, many different routes to reduce CO₂ emissions have been proposed. Of these, post-combustion CO₂ capture from coal-fired power stations is often the most controversial, as the CO₂ capture system will remove generating capacity from the grid whereas many of the other solutions involve increasing the generating capacity of the grid with low CO₂-emission plants. Despite this, coal-fired power stations represent a major point source for CO₂ emissions, and if a consensus is reached on the need to reduce CO₂ emissions, a low-cost method for capturing and storing the CO₂ released by these power plants needs to be developed. The overarching goal of this research is to design and develop a novel hollow fiber sorbent system for post-combustion CO₂ capture. To achieve this goal, three objectives were developed to guide this research: i) develop a conceptual framework for hollow fiber sorbents that focuses on the energetic requirements of the system, ii) demonstrate that hollow fiber sorbents can be created, and a defect-free lumen layer can be made, iii) perform proof-of-concept CO₂ sorption experiments to confirm the validity of this approach to CO₂ capture. Each of these objectives is addressed in the body of this dissertation. Work on the first objective showed that fiber sorbents can combine the energetic advantages of a physi-/chemi-sorption process utilizing a solid sorbent while mitigating the process deficiencies associated with using solid sorbents in a typical packed bed. All CO₂ capture technologies--including fiber sorbents--were shown to be highly parasitic to a host power plant in the absence of effective heat integration. Fiber sorbents have the unique advantage that heat integration is enabled most effectively by the hollow fiber morphology: the CO₂-sorbing fibers can behave as "adsorbing heat exchangers." A dry-jet, wet-quench based hollow fiber spinning process was utilized to spin fibers that were 75wt% solid sorbent (zeolite 13X) and 25wt% support polymer (cellulose acetate). The spinning process was consistent and repeatable, allowing for production of large quantities of fibers. The fibers were successfully post-treated with an emulsion-based polymer (polyvinylidene chloride) to create a defect-free lumen side coating that was an excellent barrier to both water and gas permeation. A film study was conducted to elucidate the dominant factors in the formation of a defect-free film, and these factors were used for the creation of defect-free lumen layers. The work discussed in this thesis shows that the second objective of this work was definitively achieved. For the third objective, sorption experiments conducted on the fiber sorbents indicated that the fiber sorbents CO₂ uptake is simply a weighted average of the support material CO₂ uptake and the solid sorbent uptake. Furthermore, kinetic experiments indicate that CO₂ access to the sorbents is not occluded noticeably by the polymer matrix. Using the fiber sorbents in a simulated rapid thermal swing adsorption cycle provided evidence for the fiber sorbents ability to capture the sorption enthalpy released by the CO₂-13X interaction. Finally, a slightly more-pure CO₂ product was able to be generated from the fiber sorbents via a thermal swing/inert purge process.

Abstract:
The application of solid adsorbents for gas separation in pre-combustion carbon capture from gasification processes has gained attention in recent times. This is due to the potential of the technology to reduce the overall energy penalty associated with the capture process. However, this requires the development of solid adsorbent materials with large selectivity, large adsorption capacity, fast adsorption kinetics for CO2 coupled with good mechanical strength and thermal stability. In this work, results on CO2 adsorption performance of three different types of adsorbents; a commercial activated carbon, phenolic resin activated carbons and zeolite templated carbons have been reported at atmospheric and high pressures conditions. The commercial activated carbon was obtained from Norit Carbons UK, the phenolic resin activated carbon was obtained from MAST Carbon Ltd., while the templated carbons were synthesized in the laboratory. A commercial activated carbon was used as bench mark for this study. Surface modification of these carbons was also undertaken and their CO2 uptake measurements at ambient and high pressure conditions were recorded. The commercial and templated carbons were modified by functionalising with amine group, while the phenolic resin carbon was modified by oxidation. The textural properties of the adsorbents was examined using the Micromeritics ASAP, while the CO2 adsorption capacities were conducted using the thermogravimetric analyser (TGA) and the High pressure volumetric analyser (HPVA). Textural properties of synthesized templated adsorbents were seen to depend on the textural characteristics of the parent material. The β-type zeolite produced the carbons with the best textural property. Increase in activation temperature and addition of furfuryl alcohol (FA) enhanced the surface area of most of the templated carbons. The textural property of all the adsorbents under study was seen to differently affect the CO2 uptake capacity at atmospheric (0.1 MPa) and high pressure conditions (up to 4 MPa). Micropore volume and surface area of the commercial activated carbons, phenolic resin activated carbons, and the templated carbons greatly influenced the adsorption trends recorded at ambient conditions. Total pore volumes positively influenced adsorption trend for templated carbons, but not the phenolic resin activated carbons at ambient and high pressure. This also positively influenced the adsorption trend for the commercial activated carbons, but at ambient conditions only. The surface area and the micropore volume have no effect on the adsorption trends for the templated carbons and the commercial activated carbons at high pressure conditions. However, these played a positive role in the adsorption capacities of the phenolic resin activated carbons at the same experimental conditions. Micropore volume and surface area of adsorbents play a major role on the adsorption trends recorded for the modified adsorbents at ambient conditions only. No trend was recorded for adsorption capacities at high pressure conditions. Only the oxidized phenolic resin activated carbon showed a positive adsorption trend with respect to total pore volume at high pressure condition. The amine modified commercial activated carbon showed no positive adsorption trend with respect to the total pore volume at both ambient and high pressure conditions, while the amine modified templated carbon showed no adsorption trend with respect to the textural properties at ambient and high pressure conditions. CO2 uptake measurements for the modified and unmodified templated carbon and phenolic resin carbon, were observed to be higher than those of the commercial activated carbon at ambient and high pressure conditions. Maximum CO2 uptake was recorded at 25 oC. At ambient pressure, the phenolic resin carbon (MC11) showed the highest CO2 uptake of approximately 3.3 mmol g-1, followed by the commercial activated carbon (2.4 mmol g-1), then, the templated carbon (2.4 mmol g-1). At high pressure, the templated carbons (β-AC7-2%) showed the highest CO2 uptake (21.3 mmol g-1), followed by phenolic resin carbon (MC4 - 12.2 mmol g-1), and the commercial activated carbon (6.6 mmol g-1). When samples were modified, the amine modified templated carbon and oxidized phenolic resin carbon showed the highest CO2 uptake of 2.9 mmol g-1 each at ambient pressure, followed by the commercial activated carbon (2.7 mmol g-1). At high pressure conditions, the oxidized phenolic resin carbon showed the highest (10.6 mmol g-1) uptake level, followed by the templated carbon (8.7 mmol g-1), and commercial activated carbon (6.5 mmol g-1).

Abstract:
Amine functionalized silicas are promising chemisorbent materials for post-combustion CO₂ capture due to the high density of active sites per unit mass of adsorbent that can be obtained by tuning the synthesis protocol, thus resulting in high equilibrium CO₂ adsorption capacities. However, when compared to physisorbents, they have a few disadvantages. Firstly, oxidative degradation of the amine groups reduces the lifetime of these adsorbent materials. Furthermore, rapid heat release following the reaction between amines and CO₂ results in large local temperature spikes which may adversely affect adsorption equilibria and kinetics. Thirdly, there is a lack of fundamental understanding of CO₂-amine adsorption thermodynamics, which is key to scaling up these materials to an industrial-scale adsorption process. In this dissertation the qualitative and quantitative understanding of these three critical aspects of aminosilica adsorbents have been furthered so these materials can be better evaluated and further tuned as adsorbents for post-combustion CO₂ capture applications.

Abstract:
Increased levels of carbon dioxide in the atmosphere are now widely attributed as a leading cause for global climate change. As such, research efforts into the capture and sequestration of CO2 from large point sources (flue gas capture) as well as the ambient atmosphere (air capture) are gaining increased popularity and importance. Supported amine materials have emerged as a promising class of materials for these applications. However, more fundamental research is needed before these materials can be used in a practically relevant process. The following areas are considered critical research needs for these materials: (i) process design, (ii) material stability, (iii) kinetics of adsorption and desorption, (iv) improved sorbent adsorption efficiency and (v) understanding the effects of water on sorbent adsorption behavior. The aim of the studies presented in this thesis is to further the scientific community’s understanding of supported amine adsorbents with respect to stability, adsorption efficiency and adsorption behavior with water.

China has been building at least 50GW of new coal‐fired power plants every year since 2004. Previous carbon capture and storage (CCS) research has mainly focussed on technology improvements or stakeholder opinion surveys, without picturing the overall concerns and barriers for deploying such technology in China. This thesis therefore explores the engineering and policy requirements to implement CCS and CO2 Capture Ready (CCR) in Chinese coal‐fired power plants, key enablers for future deployment. A preliminary study of the Chinese gasification industry shows there are early opportunities to capture carbon dioxide from gasification plants. However, as power from conventional pulverised coal (PC) accounts for the majority of electricity generated in China, the most promising emission reduction method for China could be through implementation of CCS technology in large PC plants. An investigation of the current PC plant layouts and operating parameters has been carried out during the course of the study. The results show that, in the absence of CCR designs, a large fraction of such new coal power plants built within the next decade could face ‘carbon lock-in’. A site specific system model using ASPEN Plus to demonstrate the possible changes that could be applied to an existing power plant and a retrofit plant is included in the study. A capture ready power plant site selection method has also been developed, to identify possible sites and to aid understanding of the criteria that should be considered when planning a capture ready plant. A case study of a capture ready power plant in Guangdong province, China shows the benefit of regional planning. Finally, the result of the first stakeholder perception survey on making new coal‐fired plants CCR, conducted in early 2010, are presented and analysed. Evidence for a supportive attitude towards CCR could indicate that this may be a route to early commercial demonstration of CCS in China.

Abstract:
Abstract Carbon capture and sequestration (CCS) is gaining greater importance in the industry transition to meet climate goals reducing carbon intensity. As the source of CO2 captured for sequestration widens to many more applications from oil and gas productions, power plants, refineries, chemical plants, steel manufacturing and other industries, the composition of the captured gas stream for sequestration sees various components. Some of the common impurities particularly from combustion processes are carbon monoxide, oxygen, SOx, NOx and others. Understanding the effect of presence of the various chemical species on material limits and maximum tolerance limits are crucial for safe operations of the assets. In one of the recent projects, there was a presence of CO in the CO2 stream, and it was imperative to identify the effect of this on the existing carbon steel pipeline. The pipeline was of X65 steel and fabricated for natural gas transmission. Wet CO-CO2 cracking is a reported degradation mode particularly as the CO concentration increases beyond 200 ppm in the gas phase or at partial pressures above 0.3 bar. This study is a combination of literature review of current state of art with respect to CO-CO2 cracking in carbon steel in presence of impurities and laboratory testing of welded X65 specimens exposed to CO concentration in dense (liquid) phase up to 1000 ppm and also in the presence of small concentrations of oxygen that also replicates some of the expected conditions in the project. The tests clearly indicate that the risk of CO-CO2 cracking is not significant up to the concentrations tested.

Abstract:
Abstract Carbon capture and storage (CCS) is recognized as a proven technology to potentially mitigate emissions and meet net-zero objectives. Utilization of pipeline infrastructure for transporting CO2 from capture and treatment sites to geological storage locations is a common method. It is necessary to understand the material integrity under CO2 transportation pipeline operating condition and in the presence of impurities in the CO2 stream, which can potentially cause corrosion, cracking, fracture and fatigue issues. In the previous publication (AMPP paper no. C2024-20647), it was reported that carbon steel X65 line pipe grade, both base and weld materials, exhibited pseudo-passivity with the additions of CO thus susceptible to stress corrosion cracking (SCC) under supercritical CO2 conditions with water. The presence of oxygen weakened the pseudo-passivity of carbon steel with CO impurity, resulting in higher corrosion rate and enhanced SCC susceptibility. In this follow-up study (part 2), it further explored the safe limits of CO and O2 partial pressures on SCC and acquired the key results. Additionally, this study investigated the impact of CO and O2 on fatigue behavior of carbon steels in dense phase CO2 saturated with water.
