Abstract
A process for the co-production of methanol and ammonia is described comprising the steps of: (a) forming a first synthesis gas stream by reacting a first portion of a hydrocarbon feedstock and steam in a steam reformer, (b) forming a second synthesis gas stream in parallel to the first synthesis gas stream by reacting a second portion of the hydrocarbon feedstock with an oxygen-containing gas and steam in an autothermal reformer, (c) synthesising methanol from a first process gas comprising the first synthesis gas stream, and (d) synthesising ammonia from a second process gas prepared from the second synthesis gas stream, wherein a purge stream containing hydrogen is recovered from the methanol synthesis step (c) and a portion of the purge gas stream is fed to the autothermal reformer and/or the second synthesis gas in step (b).
