Process for making ammonia from heterogeneous feedstock

Abstract From the Canadian patent

Ammonia is made from a carbon containing heterogeneous feedstock (A) by partially oxidizing the feedstock in gasifier/gas cleanup unit (1) to generate a synthesis gas containing Co; compressing the synthesis gas in compressor (2) to form a compressed synthesis gas (F) which is mixed with pressurized steam (G) to form a wet compressed synthesis gas (J); reacting the wet compressed synthesis gas (J) in shift reactor unit (3) to form H2; cryogenically removing CO2 from the shifted gas in cryogenic unit (8); feeding the gases (KK) rich in H2 leaving cryogenic unit (8) to pressure during adsorption unit (4) to obtain gas stream (L); mixing gas stream (L) with a high purity N2 stream (P) …
