Interest has been piqued in the use of membranes for the removal of bulk carbon dioxide from natural gas in an offshore environment because of the advantages that membranes present in weight, space efficiency and tolerance of motion. A number of practical considerations have to be considered when using membranes for CO2 removal offshore and these will be discussed in the context of recent KBR work.

Membranes have strengths and weaknesses compared to other carbon dioxide removal technologies in an offshore environment. These strengths and weakness lead to specific concerns and opportunities that should be addressed in the design stage and can have impacts on the full life cycle of the offshore facility if not fully addressed. We will discuss how to approach these issues to lead to successful construction, operation and maintenance of the carbon dioxide removal membrane system in an offshore environment.


Gas is becoming an increasingly important part of the global energy equation constituting 18.5% of the energy mix in 1977 which further increased to 23.5% of the mix in 2005 per Wood (2007) [Fig. 1].
