Development and demonstration of novel cryogenic distillation process for offshore gas platform

Natural gas consists of methane and other gases, which are mostly natural gas liquid (NGL), CO2, H2S and water. NGL generally refers the stream containing C2 or heavier hydrocarbons, mostly ethane and propane 5. The recovery of C2+ components from the sale gas can enhance cost-effectivness in natura...
