Ammonia production

A typical modern ammonia-producing plant first converts natural gas, liquified petroleum gas, or petroleum naphtha into gaseous hydrogen. The method for producing hydrogen from hydrocarbons is known as steam reforming. The hydrogen is then combined with nitrogen to produce ammonia via the Haber-Bosch process. Starting with a natural gas (CH 4) feedstock, the different steps used in the process of producing hydrogen are the following:

Frontiers Sustainable Ammonia Production Processes

For a 50 tonne/day ammonia production plant, 20 MW power is needed and for a 300 tonne/day of ammonia plant, 120 MW is required. Based on Will and Lukas’s study, the water loss from the cooling towers is said to be in the range of approximately 1–1.5% of the total input water. This shows that for the production of approximately 1 tonne of ammonia, 2.45 tonnes of water is required when

Optimizing the Ammonia Production Process

10/08/2016 No production manager in an ammonia plant would be satisfied operating at nameplate capacity. If the nameplate says 2,200 tons per day, he will push the plant to produce more, of course. The limit is some constraint in the process—ambient conditions, capacity, temperatures, etc. To operate at the higher-than-nameplate rate often requires adjustment to the control package used on the steam

Ammonia an overview ScienceDirect Topics

Anhydrous ammonia is made at fertilizer-manufacturing plants by converting nitrogen gas in the atmosphere into ammonia gas. The process of conversion is the Haber process or Haber-Bosch process. The gas is compressed into a liquid, which is injected in bands into soil by special equipment. The ammonia dissolves quickly in soil water and is retained in the soil. Anhydrous ammonia is the
