Ammonia Production Processes

The present chapter describes process technology for the production of ammonia. The first part gives a short review of early developments in ammonia technology. The second part contains a brief description of processes used in the production of ammonia synthesis gas, i.e. a mixture of hydrogen and nitrogen with or without minor amounts of impurities such as methane, argon, etc. A third part describes the conversion of synthesis gas to ammonia. This part includes discussion of the design of ammonia synthesis converters. A fourth part describes integrated processes for production of ammonia from primary raw materials such as hydrocarbons and coal. A final part deals with storage of ammonia.
