CO2 Removal
CO2, carbon dioxide, is found in natural gas from many sources. In order to meet pipeline or application specifications the CO2 and other contaminants, e.g.H2O and H2S, must be removed before the methane gas can be used. The GENERON® Membrane System is of simple process technology and utilizes patented GENERON Membrane Technology.
Generon IGS Membrane Technology is competing against Amine systems which are used frequently but are complex and have high capital, operating, and installation costs, a relatively high fuel cost and potential environmental issues. Advantages of the Membrane Systems are:
- No moving parts, and designed for remote unmanned operation
- efficient packaging minimizes space and weight (ideal for offshore applications)
- Optimized process design to maximize total hydrocarbon recovery
- CO2 content can be adjusted to desired specifications
- Easy installation: skidded system can be installed in hours.
In a typical GENERON® membrane system for CO2 or H2S removal the feed gas is filtered to remove particles and liquid condensate. The feed gas is then heated to an optimum operation temperature and ready to enter the GENERON® membrane modules. CO2 gas permeates preferred through the membrane walls. The non-permeated gas remains at pressure and is the high heating value product. The “faster” permeating gases, e.g. CO2 , H2O, H2S, are collected in the permeate.
