ABSTRACT:
An improved synthesis loop for the production of ammonia has a low pressure, i.e. less than 100 atmospheres, a water absorption recovery system which utilizes low level heat recovered from the process for producing the synthesis gas to distill the ammonia-water mixture and an ammonia absorption refrigeration system which utilizes the same distillation column for both the water absorption system and the refrigeration system.
