Most large coal fired plants have a flue gas desulphurisation (FGD) plant to lower SO2 levels to below emission limit levels. The CODEL GCEM 40 series is used to monitor SO2 levels after the FGD to ensure they are below required levels and to ensure that the process is not too efficient and using too much sorbent. In addition, many plants monitor pre and post the FGD to ascertain the efficiency of the plant.
Understanding of heat flow and thermal losses is inevitable during building design and engineering of energy-efficient floor heating systems. Thermal conductivity can be improved when for multilayer constructions materials are optimized.
While ordinary commercial styrene-based sulfonic acid resins may often be used for chemical reactions catalyzed by the H+ or M+ ions, faster process times, better yields, and higher product purity may be obtained by using a properly designed and purified catalyst. Purolite catalyst resins are supplied either completely water-swollen, or dried to specification.
As the alternatives to fossil fuels for power generation and automotive power become more widespread and preferred, so has increased the research and testing of hydrogen gas in fuel cells. The hydrogen (H2) gas used in fuel cell has to be free of impurities in order to make the fuel cell as efficient as possible and so quality thresholds have been set in legislation. Such legislation as SAE J2719 provides hydrogen fuel quality standards for proton exchange membrane (PEM) fuel cell vehicles. If impurities above...
Composition of Natural Gas, Syngas via VOC SpeciationThe composition of fuel gas is important in order to determine calorific value and also to detect any unwanted contaminants in the gas. Online analysis is important in order to give real-time and direct action on issues.
