[54] METHOD OF PROCESSING A FEED NATURAL GAS TO OBTAIN A PROCESSED NATURAL GAS AND A CUT OF C5+ HYDROCARBONS, AND ASSOCIATED INSTALLATION
[57] Abstract: The method comprises the introduction of a feed flow (54) into a first flask (22), the dynamic expansion of the gaseous flow (56) issuing from the flask (22) in a turbine (24), then its introduction into a first purification column (26). It comprises the production at the head of the first column (26) of a purified gas (70) and the recovery at the bottom of the first column (26) of a liquefied bottom gas (74), which is introduced, after expansion, into a second column (30) for elimination of the C5+ hydrocarbons. The purified head natural gas (70) issuing from the first column (26) is heated in a first heat exchanger (20) by thermal exchange with a feed gas (12). The method comprises the compression of the gaseous head flow (86) of the second column (30) in a compressor (38) before its introduction into a second separator flask (40). Figure 1
