Increasing capacity of a co2 removal system

Increasing capacity of a co2 removal system

Increasing capacity of a co2 removal system

(OP)
I support a syngas plant that uses the sulfinol process to remove CO2 (and very small amounts of H2S) from the syngas stream.  I am in the process of designing an improvemnt to the plant that will allow us to increase syngas production by about 10% but the sulfinol unit is already at full capacity. Any suggestions on the best ways to increase the units capacity by 10-15%?

RE: Increasing capacity of a co2 removal system

umm, this is a loaded question.  You could:

a) jack up the operating pressure to push up the CO2 partial pressure.
b) consider higher concentrations of sulfinol
c) consider a different solvent
d) use the sulfinol as a bulk removal train and do the polishing downstream.
e) look at a bulk offload upstream with membranes or solvent

There's so many options to consider and with no process info - we're just guessing.  This one is going to take a serious process study.

RE: Increasing capacity of a co2 removal system

membranes or propylene carbonate.
