ABSTRACT:
The invention relates to a process for the production of ammonia from synthesis gas, the synthesis of ammonia from synthesis gas taking place in several lined-up synthesis systems, whereby ammonia is produced from a portion of the synthesis gas in each system with a part-stream being withdrawn and the respective downstream synthesis system being operated at a higher pressure than the respective upstream synthesis system.
