Retrofit Mass Integration of Acid Gas Removal Systems in Petrochemical Plants
Duncan Mckenzie Fraser, University of Cape Town, South Africa
Acid gas removal systems are common in refineries as well as in gas treatment facilities. They are generally designed to be optimum as individual units by suppliers, but not optimised as a whole system. This chapter examines the retrofit of two industrial Mass Exchange Networks for the removal of hydrogen sulphide from process streams, in order to reduce the sulphur emissions from the plants. By optimising each of these networks as a system, it was possible to improve on the individual unit designs. The approach to retrofitting of each of these two very different systems is presented ...
