Application of ammonia in synthetic ammonia industry

N2(g) + 3H2(g) → 2NH3(g)

50-60% of industrial hydrogen production in China is used in ammonia synthesis industry. In theory, 1976 Nm3 hydrogen is needed to produce 1 t ammonia synthesis. The hydrogen source is mainly the hydrogen produced by the reaction of anthracite or coke with steam at high temperature. Or prepare hydrogen from natural gas, by-product gas from oil refinery and oil field gas.
