Brief introduction 

The process gas for industrial production of synthetic ammonia is hydrogen and nitrogen. Solid raw materials commonly used include coal and coke; Liquid raw materials: liquid hydrocarbons, naphtha, heavy oil, etc; Gas raw materials include natural gas, oilfield gas, refinery gas, coke oven gas, etc. At present, the production process of synthetic ammonia using oil, coal, or natural gas as raw materials is relatively mature, and there are corresponding industrial devices in operation worldwide.

Before the 1950s, the synthetic ammonia industry in the world mostly relied on coal, coke, or coke oven gas as raw materials. In the 1970s, the world entered a period of rapid development in the petrochemical industry, and developed countries almost abandoned the research and development of coal chemical industry. Subsequently, due to the development of oil and natural gas ammonia production processes, coal and coke were gradually replaced. From a technical perspective, natural gas is the most ideal raw material among the above. The main reason is that the process of producing synthetic ammonia using natural gas and naphtha as raw materials is simple in technology, low in cost, and easy to build large-scale units. Internationally, natural gas and crude oil are mainly used as raw materials to produce synthetic ammonia, with natural gas accounting for about 90%.

Ammonia Synthesis Project

Technological process

The project can use coke oven gas as raw material, and the H2 and N2 mixed gas after pre-treatment, desulfurization, transformation, PSA hydrogen extraction, fine desulfurization, methane purification, and methanation purification is then pressurized to 15Mpa by a combined compressor and sent to the ammonia synthesis (3H2+N2=2NH3) process to produce liquid ammonia.
