ABSTRACT:
The synthesis of ammonia from hydrogen and nitrogen is carried out in a process scheme in which a liquid material is provided to react with ammonia to form an ammine to either improve the method of recovery of ammonia from a product gas stream or to upset the thermodynamic equilibrium of the H.sub.2 --N.sub.2 --NH.sub.3 system so that higher first pass conversion of the reactant gas to ammonia can be accomplished. As a result of this invention the horsepower of the synthesis gas compressor, the catalyst inventory, the operating temperature, and the operating pressure, or combinations of these factors, are reduced, having the effect of decreasing equipment and operating costs. In addition, the liquid ammine product is decomposed under conditions that allow the recovery of the ammonia as a liquid product by heat exchange with cooling water. This markedly reduces refrigeration horsepower requirements.
