Request: anthracite as raw material for ammonia synthesis production flow chart

Ammonia is the main raw material of ammonia, our company can contract the ammonia generation of complete sets of projects, the scale of 4 × 104 tons / year, 6 × 104 tons / year, 10 × 104 tons / year, 30 × 104 tons / year, the quality of its products in line with the national standards of China.

1. Process route:

The common process of generating synthetic ammonia from anthracite as raw material is:

Gas making -> Semi-aquatic coal gas desulfurization -> Compressor 1,2 section -> Reform -> Reform gas desulfurization -> Compressor 3 section -> Desulfurization -> Compressor 4,5 section -> Copper washing -> Compressor 6 section -> Copper washing -> Compressor 6 -> ammonia synthesis -> product NH3

The ammonia synthesis process flow diagram when using methanation to desulphurize the CO2 in the raw gas is as follows:

Gas production -> half-water gas desulphurization -> Compressor 1,2 -> conversion -> converting gas desulphurization -> Compressor 3 -> decarburization -> fine desulphurization -> conversion gas desulphurization -> compressor 3 -> decarbonization -> fine desulphurization -> compressor 3 -> decarbonation -> > Fine desulphurization -> Methanation -> Compressor 4,5,6 -> Ammonia synthesis -> Product NH3
