Abstract:
The pipeline has historically been the preferred means to transport CO2 due to its low cost for short distances and opportunities for economies of scale. However, interest in vessel-based transport of CO2 is growing. While most of the literature has assumed that CO2 shipping would take place at low pressure (at 7 barg and −46 °C), the issue of identifying best transport conditions, in terms of pressure, temperature, and gas composition, is becoming more relevant as ship-based carbon capture and storage chains move towards implementation. This study focuses on an in-depth comparison of the two

Abstract:
Abstract Generally, it is well know that the bank tubes are one of the components of package boilers that fail frequently. In the investigated case the bank tube experienced a leak due to a circumferential through wall crack developed on the top half. This portion of the tube is swaged and connected to the steam drum. The failures occurred in tubes positioned in the first and second rows as a rule. The boiler has a design capacity of 140 tons per hour (140 Megagrams per hour) and is operated at a pressure of 42 barg (43 kg/cm2) and temperature of 340°C (644°F). It was commissioned in 1993. Ban

Abstract This paper presents in situ pH and corrosion rate results obtained from the tests carried out at 20bar CO2, for flexible wire material, in 3.5% NaCl, at 30°C, 40°C and 60°C with a CO2 gas flow rate of 0.001ml/min/cm2, a V/S ratio of 1ml/cm2 and a duration of 2 months. These are compared with tests at 40 barg CO2, presented in previously published work, and tests at 1barg CO2, 5barg CO2 and 10barg CO2 for similar annular test conditions. In general, the pH and corrosion behaviour were related to dissolved iron concentration, precipitation kinetics and scale formation on the surface of

Abstract:
Abstract In order to calculate the fatigue life of unbonded flexible pipes S-N curves for the armouring wires in corrosive environments are needed. No established standard method for corrosion fatigue testing exists. A test setup as well as test protocol has been developed based on deflection controlled four point bending for corrosion fatigue testing in both sour- and sweet environments. The test setup consist of an eccentric providing an alternating sinus shape loading at loading frequencies between 0.1 to 2.0 Hz. The loading is transferred to an environmental chamber containing up to 7 spec

Abstract:
Abstract Duplex stainless steels are used in concrete structures installed under highly aggressive conditions, such as marine atmosphere or areas with intense use of deicing salt. This type of bar is used when a long service life is required (over 100 years) or when there are maintenance restrictions such as inaccessibility or very high maintenance costs and disturbances to the population. Due to the high initial cost, the use of duplex stainless steel bars are restricted to the outside layer of a concrete structure which is directly subjected to a chloride contamination, whereas at the inside

Full text
Abstract:
A thermowell design standard published by ASME was recently updated to incorporate new knowledge about dynamic loads on thermowells and other factors affecting thermowell integrity and measurement accuracy. There are concerns that assumptions in the ASME standard may cause significant measurement inaccuracies or conservative designs that require significant changes to natural gas installations. To avoid thermowell damage and measure natural gas temperatures accurately, pipeline operators have requested additional guidance on thermowell design and installation.

Abstract:
This report presents the expansion of a previously introduced life-cycle cost calculation framework for concrete bridge decks in Illinois. In addition to the alternative reinforcement options examined in the Illinois Center for Transportation and Illinois Department of Transportation project R27-SP49, two additional reinforcing bar types—stainless steel–clad carbon core and textured epoxy-coated bars—are the main subjects of this study. The results of a comprehensive literature review of these two additional bar options will highlight their cost-benefit characteristics toward optimizing the li

Abstract:
The height of the jump-outs should be low enough for the target species to readily jump down to the safe side, or the habitat side, of the fence. At the same time, the jump-outs should be high enough to discourage animals that are on the habitat side of the fence from jumping up into the fenced road corridor. Previous research along US Hwy 93 North in Montana showed that only about 32% of the mule deer and about 7% of the white-tailed deer that appeared on top of the jump-outs, jumped down to safety. For this project, 10 of the jump-outs along US Hwy 93 North were lowered in height and provide

Background. In this proposal we suggest developing a common solution for three seemingly unrelated acute problems: (1) improving sustainability of fast-growing mushroom industry producing worldwide millions of tons of underutilized leftovers; (2) alleviating the epidemic of vitamin D deficiency adversely affecting the public health in both countries and in other regions; (3) reducing spoilage of perishable fruit and vegetable products leading to food wastage. Based on our previous experience we propose utilizing appropriately processed mushroom byproducts as a source of two valuable bioactive
