초록 ▼

A process for separating the components of a feed gas containing methane and heavier hydrocarbons is shown in which a recycle stream is used to satisfy the heat requirements of the process while at the same time providing a reflux to a demethanizer column to improve product recovery. The inlet gas stream is fed to a separator without first splitting the stream. A first vapor portion and a first liquid portion are produced by the separator with the first vapor portion being supplied, after expansion, to the demethanizer column at an intermediate feed position. The first liquid portion from the separator is expanded and supplied to the demethanizer column at a relatively lower feed position. Overhead vapor is removed from the column and compressed to a higher pressure. The resulting compressed recycle stream is cooled sufficiently to substantially condense it and is supplied as reflux to the demethanizer column at a top feed position.

대표청구항 ▼

[ What is claimed is:] [1.] A process for separating components of a feed gas containing methane and heavier hydrocarbons, the process comprising the steps of:feeding an inlet gas stream to a demethanizer column to produce therefrom an overhead vapor stream and a liquid bottom fraction;compressing the overhead vapor stream from the column to form a compressed recycle stream;utilizing the compressed recycle stream to satisfy heat requirements of the demethanizer column sufficient to satisfy a desired heat balance for the demethanizer column while extracting refrigeration from the process;condensing the compressed recycle stream to form a reflux and supplying the reflux to the demethanizer to control product recovery from the process.
