    摘要: A process for recovering liquefied C3 compounds from a natural gas stream containing C3 compounds which comprises (a) chilling the natural gas stream under conditions sufficient to liquefy the natural gas, whereby a mixture comprising liquid natural gas (LNG) and liquid C3 compounds is formed; (b) fractionating the mixture comprising liquid natural gas (LNG) and liquid C3 compounds in a separation zone under sub-atmospheric pressure and under conditions predetermined to vaporize a significant portion of the natural gas present while retaining the C3 compounds as a liquid fraction; and (c) recovering separately from the separation zone natural gas and liquid C3 compounds.
