Introduction to Ammonia Production - AIChE

cant quantities are produced by coal gasification; most of the gasification plants are located in China. Modern production processes The tremendous increase in ammonia demand from 1950 to 1980 necessitated larger, more-energy-efficient plants. Those decades also saw a change in design philosophy. Until that time, an ammonia plant was regarded as an assembly of unrelated units, such .

Ammonia is the main product of the fertilizer industry. Developing countries account for the majority of worldwide production. About 77% of ammonia production is based on steam reforming of natural gas, with most of the remaining production based on heavy-oil or coal-based processes. A further shift from heavy-oil or coal-based to gas-based processes can strongly reduce energy use and emissions.
