USE OF RENEWABLE ENERGY IN AMMONIA SYNTHESIS Russian patent published in 2024 - IPC C01C1/04 C01C1/12 C01B3/12 C01B3/34 C01B3/48 C01B3/56 

FIELD: chemistry.

SUBSTANCE: invention can be used in chemical industry. Disclosed is an ammonia synthesis plant, comprising a feedstock pretreatment section configured to remove undesirable components from a feedstock stream containing natural gas, methane, propane, butane, LPG, naphtha, coal, petroleum coke or a combination thereof, by adjusting the temperature and/or pressure of pretreatment; syngas production section configured to reform the feed stream to produce a stream of reforming reactor products. Apparatus also includes a shift reaction section configured to perform a water gas shift reaction in the reforming reactor product stream to produce a shear gas stream containing more hydrogen than the reforming reactor gas stream; a purification section configured to remove at least one component from the sheared gas stream and obtain an ammonia synthesis feed stream containing hydrogen and nitrogen; ammonia synthesis section comprising one or more ammonia synthesis reactors. Ammonia synthesis plant is configured to consume 25 MW or more of electrical energy, wherein the amount of CO₂ formed per ton of ammonia is 1.6 tons of CO₂ or less per ton of ammonia obtained, and specific power consumption is 12 GJ or less per ton of produced ammonia. Ammonia synthesis plant is configured in such a way that more than 50% of the useful energy consumed by the raw material pretreatment section, the synthesis gas generation section, section of conversion by shear reaction, section of purification and section of ammonia synthesis, is provided by electric power. Also disclosed is a method of producing ammonia.

EFFECT: group of inventions increases energy efficiency of the ammonia synthesis process while simultaneously reducing emissions of carbon dioxide into the environment.
