Abstract

See full text

In a process for the production of substitute natural gas, a feed gas is provided to a first and/or second and/or subsequent bulk methanator. The feed gas is subjected to methanation in the presence of a suitable catalyst. An at least partially reacted stream from the first bulk methanator is removed and supplied to the second and/or subsequent bulk methanator where it is subjected to further methanation. A product stream from the final bulk methanator is passed to a trim methanator train where it is subjected to further methanation. A recycle stream is removed downstream of the first, second or subsequent bulk methanator, and, in any order, passed through a compressor, subjected to cooling and then supplied to a trim and/or recycle methanator for further methanation before being recycled to the first and/or second and/or subsequent methanator.
