Abstract
A methane-rich gas from synthesis gas is made in a methane reactor with a row of methanation stages and, at an upstream end of the row of methanation stages, a CO conversion stage. An incoming stream of synthesis gas containing CO and His split into a plurality of partial streams, one of which is fed to the reactor upstream of the CO conversion stage. Each of the other partial syngas streams is fed to the reactor upstream of a respective one of the methanation stages such that methanation takes place in each of the methanation stages and gas exits from the stages and mixes with the partial syngas stream being fed to the next downstream stage. A plurality of partial streams are diverted from a product-gas stream issuing from the furthest downstream stage and are each fed to the reactor upstream of a respective one of the methanation stages.
