Abstract
A process for producing a gas stream for ammonia synthesis in which a gas stream containing hydrogen and nitrogen in excess of ammonia synthesis requirements, e.g. obtained by partial oxidation of natural gas, coal or oil, is treated to remove other component gases and thereafter subjected to a separation stage, e.g. in a cryogenic separator, to separate a hydrogen-nitrogen stream having the desired hydrogen:nitrogen ratio which is injected into the reactor for ammonia synthesis, and a waste nitrogen stream which may be utilized in power generation or washing stages.
