FIELD: chemistry.
SUBSTANCE: invention relates to production of ammonia based on reforming hydrocarbons, in particular, to a method of increasing capacity of an ammonia plant. Method comprises increasing amount of hydrogen produced by a reforming section, by replacement of pipes of primary reformer with new pipes having smaller thickness, to increase inner diameter of pipes, and installing an oxygen source for enrichment with oxygen, provided said source, of air fed into secondary reformer, upgrading air compressor by installing new stator and rotor parts, to increase flow rate of air supplied into secondary reformer, while maintaining previous output pressure, as well as upgrading section for removal of CO2, of synthesis gas compressor, drying unit of synthesis gas and ammonia synthesis loop.
EFFECT: higher efficiency of apparatus for producing ammonia.
