Paper Number: OTC-31220-MS
... Abstract Reducing CO 2 emissions is becoming one of the core targets for countries after the Paris agreement, which sets out a global framework to avoid dangerous climate change by limiting global warming to below 2°C and pursuing efforts to limit it to 1.5°C. To meet this objective also oil...

... separation is a cost effective way to remove CO 2 from natural gas. The typical offshore membrane treatment package usually consists of a relatively complex pre-treatment step followed by a simple membrane system to remove CO 2 . The solution using only membranes for gas treatment consists of: a first...
