Abstract
The present invention provides a membrane/amine column system and process for removing acid gases from natural gas on a floating liquefied natural gas vessel. Several process configurations are provided to deal with a reduction in the effectiveness of the amine column by increasing the amount of acid gases being removed by the membrane system prior to the natural gas being sent to the amine column.
