SULFUR RECOVERY FROM ACID GAS BY THE CLAUS PROCCES USING ASPEN HYSYS

Abstract

Due to the many environmental impacts caused by oil refineries worldwide, and the severity of it mainly due to gas flaring of harmful gases such as acid gas, A Sulphur recovery unit consisting of a burner and then a number of reactors to increase the efficiency was used. The study is carried out following standard scientific approach of theoretical study; a simulation was done using Aspen HYSYS which yielded material and energy balance for the process, and optimum oxygen needed as well as overall efficiency which was 97.5%
