Abstract

A process for improving the hydrogen content of a synthesis gas stream to a synthesis loop, comprising the steps of: (a) removing a purge stream comprising hydrogen and hydrocarbons from a synthesis loop; (b) separating hydrogen from the purge stream; (c) passing the purge stream to a reformer and reacting with steam and oxygen to produce a stream comprising hydrogen and carbon monoxide; (d) subjecting the reformed reaction product stream to a shift reaction to produce a stream comprising carbon dioxide and hydrogen; (e) subjecting the product stream from the shift reaction to separation to separate hydrogen from carbon dioxide; (f) supplying the separated hydrogen to the synthesis loop; and (g) removing the carbon dioxide.
