Abstract
Ammonia is a highly liquid product that is used for the production of mineral fertilizers, explosives and polymers, nitric acid and other chemical products. The discovery of the reaction of its synthesis and commercial production using Haber-Bosch process became an outstanding achievement of the chemical science and industry at the beginning of the 20th century. At present, ammonia production technologies, while continuing to develop, have practically reached their perfection. Various technologies of ammonia production are considered in the paper; their characteristics are given. Megammonia technology, developed by the company «Casale» in conjunction with the company «Lurgi» is the most promising one. It allows building large-capacity ammonia aggregates in one technological line with a capacity of 5000 tons/day and above. Advantages of Megammonia technology make it possible to create units with low energy consumption, reaching 6,4 Gcal / ton of ammonia. As a result, the cost of production of ammonia can be reduced by 40 % compared to traditional technologies.
