Title: Method and apparatus for manufacturing ammonia
Inventor: GAM ERIK ANDREAS
IPC: B01J8/04
Filed: 2001-02-07
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing ammonia by a stepwise reaction through at least three catalyst beds in an ammonia reaction apparatus under high pressure and high temperature, wherein a partially reacted reaction desorbed from the catalyst beds is heat-exchanged by using heat exchangers arranged between the catalyst beds to intermediately cool the desorbed reaction gas and to take out an effluent of ammonia-rich product. SOLUTION: A process stream for ammonia synthesis is passed on at least three catalyst beds containing iron in order, then reacted. A partially converted synthetic gas desorbed from the beds is cooled intermediately through heat exchangers arranged in every bed, then an ammonia-rich gas mixture is taken out from the apparatus. The process stream is obtained by mixing a first supply stream of the synthetic gas which preliminarily is heated by indirect heat exchange, with a second supply stream of the synthetic gas for temperature control of the process stream before introduced to the first catalyst bed, while the partially converted gas is cooled intermediately. The first supply stream is passed in order through the interbed heat exchanger for cooling the partially converted synthetic gas.  Space velocity of the process gas stream in the second bed is 0.65-2.00 times as large as in the first bed.
