Abstract

See full text

The method includes the introduction of a feed flow into a first flask, the dynamic; expansion of the gaseous flow issuing from the flask in a turbine, then its introduction into a first purification column. It comprises the production at the head of the first column of a purified gas and the recovery at the bottom of the first column of a liquefied bottom gas, which is introduced, after expansion, into a second column for elimination of the C5+ hydrocarbons. The purified head natural gas issuing from the first column is heated in a first heat exchanger by thermal exchange with a feed gas. The method includes the compression of the gaseous head flow of the second column in a compressor before its introduction into a second separator flask.
