摘要：
3S separator which has been widely employed in separation of gas mixtures can greatly reduce the temperature of natural gas when it expands in a Laval nozzle. The gas through the separator can not be totally liquefied due to the special working mechanism of the separator. A novel liquefaction process with a supersonic swirling separator is presented and simulated. The process can liquefy all the crude gas by re-cycling the gas which is not liquefied at the outlet of the separator. The simulations show it can get relatively high energy efficiency and could be competitive in many cases.
