Capital Cost

← Previous | Next →

This is a standard capital cost result screen. The following process areas are shown:

•Sulfur Removal System - Hydrolyzer: This is the capital cost for the hydrolyzer system, which converts carbonyl sulfide to hydrogen sulfide.

•Sulfur Removal System - Sulfinol: H2S in the syngas is removed through counter-current contact with the solvent. The cost of the Sulfinol section includes the acid gas absorber, syngas knock-out drum, syngas heat exchanger, flash drum, lean solvent cooler, mechanical refrigeration unit, lean/rich solvent heat exchanger, solvent regenerator, regenerator air-cooled overhead condenser, acid gas knock-out drum, regenerator reboiler, and pumps and expanders associated with the Sulfinol process.

•Sulfur Recovery System - Claus: The Claus plant contains a two-stage sulfur furnace, sulfur condensers, and catalysts.

•Tail Gas Clean Up - Beavon-Stretford: The capital cost of a Beavon-Stretford unit varies with the volume flow rate of the input gas streams and with the mass flow rate of the sulfur produced. The regression model is based only on the sulfur produced by the Beavon-Stretford process.
