Abstract:
Industries must develop methods for raw material processing with greater vigilance than before due to
stricter environmental laws. Sulfur emissions are the most pressing environmental risk associated with
the processing of fossil fuels. The raw natural gas extracted from wells is a blend of several types of
hydrocarbons in different proportions, along with notable levels of impurities such as carbon dioxide,
hydrogen sulfide, mercaptans, and organic compounds that include nitrogen. As a result, downstream
applications are not appropriate for natural gas in its basic form. A method known as "sweetening of Acid
gas" is used to remove sulfur pollutants from natural gas, which is referred to as "Acid gas.". Two streams
are produced because of the amine absorption process utilized in the sweetening process: sweetened
natural gas that is ready for use as fuel or as a feedstock for the chemical industry, and a mixture of
gaseous pollutants known as acid gas when it contains a high concentration of sulfur and carbon dioxide.
The goal of this project is to recover sulfur from acid gases that are released from a natural gas processing
plant's absorption unit. Modified Claus Process along with Super Claus Reactor, a refined and enhanced
version of Claus Process, is the method used for sulfur recovery. The last catalytic packed bed reactor of
the three is equipped with a specialized selective oxidation catalyst thanks to this technique. The goal is
to recover as much elemental sulfur as possible from the acid gas stream to almost eliminate sulfur
emissions. The recovered sulfur will then serve as a feedstock for Sulfuric Acid Production for that we use
the Double Contact Double Absorption Process to get economic benefits and meet the demand of the
market.
