Abstract:
AbstractIn many industries and processes, heat exchangers are of vital importance as they are used to transfer heat from one fluid to another. These fluids can be corrosive to heat exchangers, which are usually made of metallic materials. This paper illustrates that corrosion is an important problem in the operation of heat exchangers in many environments, for which no straightforward answer exists. Corrosion failures of heat exchangers are common, and corrosion often involves high maintenance or repair costs. In this review, an overview is given of what is known on corrosion in heat exchangers. The different types of corrosion encountered in heat exchangers and the susceptible places in the devices are discussed first. This is combined with an overview of failure analyses for each type of corrosion. Next, the effect of heat transfer on corrosion and the influence of corrosion on the thermohydraulic performances are discussed. Finally, the prevention and control of corrosion is tackled. Prevention goes from general design considerations and operation guidelines to the use of cathodic and anodic protection.

Abstract:
The heat exchanger in a gas instantaneous water heater is a thermal device used for heat transfer from the high-temperature flue gas to the low-temperature water. The fireside corrosion, due to the reaction of acidic condensate formed on the heat exchanger surfaces and its metallic material, is one of the major hazards for gas instantaneous water heaters. This paper focuses on identifying and quantifying the fireside corrosion on the surface of heat exchangers in gas-fired instantaneous water heaters. Durability tests lasting for 2000 cycles were undertaken for five gas-fired instantaneous water heaters, which were different in terms of the heat input and coating of heat exchangers. The corrosion deposits on the surface of the heat exchangers were surveyed by several methods. The results show that the corrosion deposit grew as the test duration increased. The fins of the heat exchanger with a lead coating had been corroded and copper was exposed. Cu4(OH)6SO4 was the main corrosion product of heat exchangers without a lead coating, whereas PbSO4 was the main corrosion product of heat exchangers with a lead coating. The experiments demonstrate that the corrosion rate decreased with the increase of the heat input. The experiments also show that the thermal efficiency of gas instantaneous water heaters decreased by 2.4% to 6% at the end of the test duration.

Abstract:
The manufacturing of plate heat exchangers is much more difficult than that of making traditional heat exchangers. The demand of increased corrosion resistance, avoiding Cu ion contamination, resisting to high-temperature resulting from various applied environments makes the traditional Cu brazed 316 stainless steel (316SS) plate heat exchanger fail to satisfy certain applications. Corrosion-resistant brazed 316SS plate heat exchangers are successfully developed using two commercially available Ni-based brazing foils, and they are valuable for industrial applications.

Abstract:
Each machine and energetic equipment needs maintenance or cleaning time. Energetic equipment needs more regular cleaning so it works well and reliably, and the heat transfer is permanent and there is no energy loss. The inner surface of heating systems are successively covering during their operation, due to the chemical and physico-chemical reactions, solid, some dirt, minerals and corrosion products. It is therefore advisable to regularly clean and service these devices. The article deals with the distribution of exchangers, formation of sediments and corrosion products associated with their operation. In addition, the article describes the types of internal surface cleaning methods. The whole article ends with a chemical cleaning experiment, where the heat exchanger clogged with mineral deposits was cleaned. The defectoscopic images show how the chemical can remove all deposits and restore the exchanger flow to its original state.

Abstract:
Polymeric hollow fibre heat exchangers are the new alternative to common metal heat exchangers. These heat exchangers provide advantages, such as low weight, corrosion resistance, easy shaping and machining. Moreover, they consume less energy during their production. Therefore, they are environmentally friendly. The paper deals with shell & tube heat exchangers, which consist of hundreds of polymeric hollow fibres. The structure of the heat transfer surfaces has a significant influence on the effectivity of the use of the heat transfer area that is formed by the polymeric hollow fibres. The study gives a comparison of heat exchangers with an identical outer volume. The difference between them is in the structure of the heat transfer insert. One of the presented heat exchangers has fibres that are in-line and the second heat exchanger has staggered fibres. The study also pays attention to the difference in differential pressures caused by the difference in the structure of the heat transfer surfaces.

Abstract:
The HVAC&R industry is looking to transition from copper-aluminum heat exchangers to all-aluminum microchannel technology. The want for the transition stemmed from seeing the performance improvement of all-aluminum microchannel radiators in the automotive industry. Applications differ between the two industries; therefore, applying this technology for HVAC&R use must be validated. Research towards operating modes of an all-aluminum heat exchanger in a defined corrosive environment will provide the industry with a better understanding of heat exchanger design and heat exchanger material selection. The worth in this is preventing overdesign and producing more efficient heat exchangers. Furthermore, ASHRAE members and the corrosion community will find value in a defined corrosion system and corrosion test procedure. The information gained through past research has progressed assessment of material performance; however, the methods improperly simulate and expedite natural weathering. The most common method being used is the ASTM (American Society of Testing Materials) Sea Water Acetic Acid Test. The research discussed in this paper was focused on improving a standard corrosion system by implementing system modifications to simulate heat exchanger operation while performing a modified wet-dry cyclic test (e.g. ASTM G85 Annex 5). The goal is to produce results that are more representative of natural corrosion behavior and its forms. Current results were gathered from five of ten samples that underwent initial testing. Finally, possible improvements towards the chamber system and the test method, including the salt solution, are discussed.

Full text
Abstract:
All-aluminum microchannel heat exchangers are designed to significantly reduce refrigerant charge requirements, weight, reduced brazed joints, and decreased potential for leakage by increasing reliability. Al 3003 alloy is corrosion resistant and can be formed, welded, and brazed but the issue with all-aluminum heat exchangers is localized corrosion (pitting) in corrosive environments. Currently, there is no universally accepted corrosion test that all coil manufacturers use to characterize their products. Electrochemical testing method of cyclic polarization was employed in this investigation and relevant parameters including electrolyte corrosive agent and its concentration, electrolyte pH, and applied potential scan rate was varied to find an optimal set of parameters. Results of cyclic polarization of Al 3003 in electrolytes containing various concentrations of NaCl were compared with those of the tests in Sea Water Acidified Accelerated Test (SWAAT) electrolyte and it is shown the SWAAT electrolyte (4.2% sea salt acidified to pH of 2.9) is by far stronger (in terms of corrosivity) than typical 3.5% NaCl solution used in most corrosion testing. Corrosion rates (g/m2yr) of Al 3003 measured in this investigation were comparable to those provided by ISO 9223 standard corresponding to C1 through CX categories. Duration of cyclic polarization test is much shorter than that of SWAAT and results obtained in this test is more reproducible compared to those of SWAAT. Scanning electron microscopy micrographs show typical pit depths of about 50 μm.

Abstract:
Silicon nitride (Si3N4) is a potentially good ceramic material for industrial heat exchangers. However, at elevated temperatures and in coal combustion atmospheres its lifetime is severely reduced by oxidation. To increase its corrosion resistance, the formation of a protective oxidation barrier layer was promoted by the deposition of oxide thin films. Homogeneous and crack-free oxide coatings of calcium magnesium zirconium phosphate (CMZP) and magnesium doped aluminum titanate (Mg-doped Al2TiO5) were successfully deposited on Si3N4 using the sol-gel and dip-coating technique. Coated and uncoated samples were then exposed to a sodium containing atmosphere at 1000*C for 360 hours to simulate typical industrial environment conditions. Structural post-exposure analyses based on weight loss measurements and mechanical tests indicated better corrosion resistance and strength retention for CMZP coated Si3N4 compared to as received and Mg-doped Al2TiO5 coated Si3N4. This difference was attributed to the protective nature of the corrosion layer, which in the case of CMZP, significantly impeded the inward diffusion of oxygen to the Si3N4 surface.

Corrosion responses of some carbon steels, stainless steel and copper alloys in the presence of a culture of bacteria (referred to as SRB-Sulphate-reducing bacteria) found in industrial heat exchangers, was studied to recommend best alloys under this service condition, with techno-economic consideration. Water from cooling towers in three plants in a petrochemical processing complex were analysed for SRB presence. Two of the water samples showed positive indication of SRB presence. The mixed cultures obtained from plant one were grown in prepared media and incubated at 35 °C for 18 days. Potentiodynamic polarisation studies in anaerobic conditions were done on the selected alloys in aqueous media with and without the grown SRB. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) were then used to study the corrosion morphology and corrosion products formation. The voltamograms show higher icorr for alloys under the SRB compared to the control media, indicating the SRB indeed increased the corrosion rates. The surface analysis showed pitting on steel alloy ASTM A106-B. Localised attack to the grain boundaries on a selective area, was seen on ASTM A516-70 dislodging the grains, and intergranular corrosion was seen throughout the exposed area of ASTM A179. Copper alloys showed pitting on ASTM B111 grade C71500 (70-30), and denickelification on ASTM B111 grade C70600 (90-10), and is a good alternative material for use apart from carbon steel alloys, recording a low corrosion rate of 0.05 mm/year. The EDS analysis supported the findings showing higher weight percent of iron and sulphur on surface of the alloys after exposure to the SRB media. This implies that the presence of the sulphur ion indeed increased the corrosion rate. ASTM A516-70 carbon steel was chosen as a suitable alternative material to the stainless steel in this environment. The Tafel plot recorded a corrosion rate of 1.08 mm/year for ASTM A516-70 when exposed to SRB media.

Abstract:
O mexilhão-dourado é um organismo invasor que tem causado grandes prejuízos a sistemas de captação de água e usinas hidroelétricas (UHEs). Existem diversos métodos de controle da incrustação destes organismos em tubulações de usinas hidroelétricas, porém o impacto da aplicação desses métodos ainda não é amplamente conhecido. Este trabalho visa desenvolver uma metodologia para avaliar a degradação dos sistemas de resfriamento de UHEs submetidas a tratamentos químicos para o controle da incrustação por mexilhão-dourado. Neste trabalho é usado, como caso exemplo, o sistema de resfriamento do ar do núcleo do gerador e do óleo dos mancais de uma UHE com turbina Kaplan de potência aproximada de 150 MW. A análise proposta baseia-se na aplicação de ensaios acelerados de corrosão, a fim de determinar a taxa de corrosão nas condições normais de operação. Os ensaios executados neste estudo simulam condições operacionais mais severas do que as usualmente enfrentadas pelo sistema, visando reduzir o tempo de execução dos ensaios. Os ensaios acelerados de corrosão baseiam-se no aumento da solicitação térmica e da concentração das substâncias químicas injetadas no fluxo de água que são a adição de gás ozônio e de hipoclorito de sódio. Para realização dos ensaios foi construído um circuito experimental capaz de impor condições de temperatura e concentrações das substâncias químicas. Os resultados dos ensaios acelerados fornecem subsídios para aplicação dos conceitos de confiabilidade estrutural para determinação da probabilidade de falha dos equipamentos em estudo em função do tempo de aplicação do tratamento químico. Verificou-se entre os produtos químicos utilizados neste estudo, que o hipoclorito de sódio é 50% mais agressivo para a liga de cobre níquel e 700% mais agressivo para o aço inoxidável em relação a degradação observada pela ação do ozônio.
The golden mussel (Limnoperna fortunei) is an invader organism that has caused great damage to water catchment systems and hydroelectric power plants. There are various methods of fouling control of these organisms in hydroelectric power plants pipelines, but the impact of the application of these methods is not yet widely known. This work aims at developing a methodology to evaluate the degradation of hydroelectric power plants cooling systems pieces of equipment subjected to chemical treatments for control of golden mussel fouling. This work uses as a case example, the cooling system inside generator and oil bearing of Kaplan hydroelectric turbine with 150MW nominal power output. The analysis is based on the application of accelerated corrosion tests in order to determine the rate of corrosion under normal operation conditions given the rates of corrosion under various accelerated conditions. The tests run on this thesis simulate operating conditions more severe than those usually experienced by the system, to reduce the runtime of the tests. The proposed accelerated corrosion tests are based on increased thermal loading and concentration of chemical substances injected into water flow. The chemical treatments tested in this work are the addition of ozone and sodium hypochlorite. For carrying out the tests an experimental circuit capable of imposing different conditions of temperature and concentration levels was built. The results of accelerated tests provide subsidies for the implementation of structural reliability concepts for determining the failure probability of equipment under consideration. Among the chemical products used in the analysis, the sodium hypochlorite is 50% more aggressive for copper-nickel 90/10 alloy and 700% more aggressive for stainless steel in relation to degradation observed for ozone.

Abstract:
Supercritical Carbon Dioxide (S-CO2) is an efficient and flexible working fluid for power production. Research to interface S-CO2 systems with nuclear, thermal solar, and fossil energy sources are currently underway. To proceed, we must address concerns regarding high temperature compatibility of materials and compatibility between significantly different heat transfer fluids. Dry, pure S-CO2 is thought to be relatively inert [1], while ppm levels of water and oxygen result in formation of a protective chromia layer and iron oxide [2]. Thin oxides are favorable as diffusion barriers, and for their minimal impact on heat transfer. Chromia, however, is soluble in molten salt systems (nitrate, chloride, and fluoride based salts) [3–8]. Fluoride anion based systems required the development of the alloy INOR-8 (Hastelloy N, base nickel, 17%Mo) [9] to ensure that chromium diffusion is minimized, thereby maximizing the life of containment vessels. This paper reviews the thermodynamic and kinetic considerations for promising, industrially available materials for both salt and S-CO2 systems.

Abstract:
Tube side corrosion in heat exchangers is a major concern in the design and operation of these equipment. This paper describes a particularly serious occurrence of what was interpreted to be Microbiologically Increased Corrosion (MIC) in a carbon steel condenser that lead to premature failure of the tubes by perforated corrosion pits. The photographs in the text illustrate the problem and proposed cures are discussed in the conclusions.

Abstract:
Aluminum Plate Fin Heat Exchangers (Al-PFHE) are often used in low temperature applications of chemical plants when huge heat transfer capacities are required. Typically the equipment is insulated or installed in insulated containments — so called “Cold Boxes”. Al-PFHE may either fail by corrosion or by mechanical overload due to trip scenarios or blockage / fouling. No failures due to mechanical overload should occur under the conditions of the ALPEMA [9] guideline (ALPEMA = Aluminum Plate-fin Heat Exchanger Manufacturer’s Association). However, ALPEMA doesn’t describe all operational situations in the exchanger block itself and the ALPEMA load conditions are not followed in all cases. The specific design of Al-PFHE does not allow standard inspection and maintenance procedures, which makes it difficult to evaluate the equipment condition and the expected remaining service life. Corrosion, blockage, fouling, and mechanical/thermal overload are the key degradation mechanisms that operators need to control to avoid premature failure of their aluminum plate fin heat exchangers. This paper describes how to incorporate finite element analysis and dynamic process simulation in the design and operation to evaluate the lifetime of Al-PFHE.

Abstract:
In response to the technical challenges faced by aging plant systems and components at nuclear power plants (NPP), the Electric Power Research Institute (EPRI) has a product entitled Integrated Life Cycle Management (ILCM). The ILCM software is a quantitative tool that supports capital asset and component replacement decision-making at NPPs. ILCM is comprised of models that predict the probability of failure (PoF) over time for various high-value components such as steam generators, turbines, generators, etc. The PoF models allow the user to schedule replacements at the optimum time, thereby reducing unplanned equipment shutdowns and costs. This paper describes a mathematical model that was developed for critical heat exchangers in a power plant. The heat exchanger model calculates the probability of the tubes, shell, or internals failing individually, and then accumulates the failures across the heat exchanger sub-components. The dominant degradation mechanisms addressed by the model include stress corrosion cracking, wear, microbiologically influenced corrosion, flow accelerated corrosion, and particle-induced erosion. The heat exchanger model combines physics-based algorithms and operating experience distributions to predict the cumulative PoF over time. The model is applicable to shell and tube heat exchangers and air-to-water heat exchangers. Many different types of fluids including open cycle fresh water, closed cycle fresh water, sea water, brackish water, air, closed cooling water, steam, oil, primary water, and condensate are included. Examples of PoF over time plots are also provided for different fluid types and operating conditions.

Abstract:
The present study explores the thermofluid characteristics of a seawater-methane heat exchanger that could be used in the liquefaction of natural gas on offshore platforms. The compression process generates large amounts of heat, usually dissipated via plate heat exchangers using seawater as a convenient cooling fluid. Such an application mandates the use of a corrosion resistant material. Metals such as titanium, expensive in terms of both energy and currency, are a common choice. The “total coefficient of performance,” or COPT, which incorporates the energy required to manufacture a heat exchanger along with the pumping power expended over the lifetime of the heat exchanger, is used to compare conventional metallic materials to thermally conductive polymers. The results reveal that heat exchangers fabricated of low energy, low thermal conductivity polymers can perform as well as, or better than, those fabricated of conventional materials, over the full lifecycle of the heat exchanger. Analysis of a prototypical seawater-methane heat exchanger, built from a thermally conductive polymer, suggests that a COPT nearly double that of aluminum, and more than ten times that of titanium, could be achieved.
