Abstract

H2S is removed from sour syngas upstream of CO2 capture, thus producing sweeter syngas. Simulation results of H2S absorption in a physical or chemical solvent may be unreliable due to assumptions like the equilibrium based modelling, theoretical number of stages, tray efficiency, height equivalent of theoretical plate, as also due to the lack of prior experience and the lack of pilot plant data at appropriate scale of operation. Rate based process simulations carried out using ProTreat software are described in this publication using process flow diagram (PFD) and simulation flow sheet – to describe the packed tower design and process design for H2S Absorption from syngas in physical solvent DMEPEG. Consideration of physical model of packed tower (packing type, size and material) imparts credibility to the simulation results. Sensitivity analysis is conducted for process parameters. Performance of packer tower is analysed and compared with process requirement and recommended practice. Similar performing tower internals are suggested.
