Poe, Saeid Mokhatab, in Modeling, Control, and Optimization of Natural Gas Processing Plants, 2017 1.3.1.3.1 Chemical Solvent Processes Chemical absorption processes, in which the H 2 S, CO 2 , and to some extent COS are chemically absorbed, will not remove mercaptans down to low levels due to the low solubility of these components. Animals or plants of microscopic size. disease, any harmful deviation from the normal structural or functional state of an organism, generally associated with certain signs and symptoms and differing in nature from physical injury.A diseased organism commonly exhibits signs or symptoms indicative of its abnormal state. Like most pests, the best control for aphids is defensive. From energy-harvesting textiles to better batteries and solar cells to new materials for hydrogen storage and for electrocatalysis, the Chemical Engineering Department is doing the research that will enable increased use of renewable energy sources.
