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systems, whereby ammonia is produced from a portion of the synthesis gas in each system with a part-stream being withdrawn and the respective downstream synthesis system being operated at a higher pressure than the respective upstream synthesis system.
Claims10
A process for the production of ammonia from fresh synthesis gas, which contains inert components apart from the reactants hydrogen and nitrogen, takes place in at least two reaction systems which comprise lined-up synthesis systems including a first system and a last system, wherein ammonia is produced from a portion of the synthesis gas in each of the at least two systems with a part stream being withdrawn, and the respective downstream synthesis system operates at a higher pressure than the respective upstream system.
