  • Patent number: 9404685
    Abstract: A process for dehydrating and removing heavy hydrocarbons in the production of liquefied natural gas from a methane-rich gas mixture is disclosed, wherein the methane-rich gas mixture subjected to deacidification treatment is divided into two streams, i.e. the first stream and the second stream, wherein the first stream used as a system process gas is introduced into a drying procedure, and the second stream used as regenerating gas is introduced into a regenerating procedure; the first stream is subjected to a drying treatment, and the moisture and the heavy hydrocarbons are simultaneously removed from the first stream in a composite adsorbent bed(s) of a drying tower, wherein the moisture is removed such that the dew point at normal pressure is ??76° C.
