Crude oil and natural gas contain acid gases (H2S and CO2) and associated impurities, such as benzene, toluene and xylene (BTX) that are all harmful to human health, environment and industrial equipment. It is often required to process crude oil and gas using highly efficient desulfurization processes prior to use as a fuel. The separated acid gases (byproducts of desulfurization) are further processed in Claus process plants to recover chemical and thermal energy. Currently, BTX and other associated impurities present in acid gas cause several technical and operational problems that result...
