CO₂ is commonly found in natural gas. In order to meet pipeline specifications or other application specific requirements, the CO₂ has to be removed. In addition, there may also be H₂S and H₂O present that needs to be removed. Membranes have been widely used for CO₂ removal applications and come with the added benefit of removing H₂S and H₂O as well.

SMC-IGS supplies customized CO₂ removal systems. IGS fabricates its own membrane modules and works directly with the client to provide the most cost effective solution.

Bulk removal upstream of an amine plant

SMC CO₂ removal membrane system the feed gas is first filtered to remove any particles and liquid condensate. The gas then enters the membrane modules. The CO₂ as well as any H₂S and H₂O permeate preferably through the membrane. The non-permeated gas, mainly CH₄, remains at pressure and is the product gas.

Performance

• Feed gas pressures up to 2,000psi (138bar)

• > 60 vol% CO₂ in feed

• < 2% CO₂ content in product

• > 98% recovery of hydrocarbon gas

• > 90% removal of CO₂

• Flow rates: 20~500,000Nm³/h
