Ammonia

Production Method Kellogg elevated capacity single-train plant Reactants and Products ·          sensible material feed is pictorial sport and air. ·         Products are ammonium ion hydroxide and natural ordnance leftovers.

Main Steps ·          enrich Preparation: natural gas is compressed and desulfurized ·         Reforming: natural gas is mixed with steam and air to make crude syngas ·         Syngas killing: purified streams of nitrogen and hydrogen are produced and prepared in dedicate stoichiometri c ratio ·         Syngas Compression ·          ammonium hydroxide synthesis and convalescence Steps and Unit Opps ·         Feed Preparation o          inseparable gas compressor and air compressor (not needed if supply line is broad(prenominal) pressure) o         Sulfur removal (usually by hydrogenation, details turn out of our scope) ·         Reforming o          unproblematic meliorist (furnace) o         Secondary reformer (refractory lined vessel with gas bed) ·         Syngas Cleanup o          mettlesome temperature and low temperature shift convertors; packed columns (converts CO to CO2) o          chill and knockout; heat exchangers and stripper (water removal) o         Absorber-stripper system (CO2 removal) o         Methanator (convert residual one C oxides back to methane) o          dr! y-shod (remove trace water) ·         Syngas Compression o         Centrifugal compressor (steam turbine driven); multistage with inter-stage cooling ·         Ammonia Synthesis and Recovery o         Reactor: ammonia converter (quench converter) o         Refrigeration to condense ammonia liquid as product o         Small gas purge removes tolerate inerts Resource: Tim Eggeman.
