Natural Gas Sweetening - Pipeline and Offshore  [ Return towards  Natural Gas Sweetening  ]

• Multi-stage Membrane Systems for Pipeline and Offshore

Membrane technology presents a significant advantage for the offshore industry. Multi-stage membrane systems are much more compact and lighter than conventional process equipment. Removal of CO2 improves offshore production economics and reduces carbon steel pipeline corrosion.

Applications requiring a high recovery (low loss) of natural gas can be treated using a multi-stage system to ensure greater than a 95% of the natural gas is maintained in the process. 




membrane in a 3-stage system for treatment of 43,000 Nm3/h of natural gas with 19% CO2 - (Argentina).

• Reduced system size (footprint and weight for offshore operation)
• Simplicity of operation
• Environmentally friendly alternative to traditional amine process
• Low capital investment
