METHOD OF PRODUCING AMMONIA AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2012 - IPC C01C1/04 

FIELD: chemistry.

SUBSTANCE: coal undergoes gasification via partial oxidation in a gasification furnace 2 consisting of a hearth 2a and a gasification chamber 2b. In a desulphurisation apparatus 3, having a wet cleaning 3a and a dry cleaning section 3b, hydrogen sulphide is removed from gas generated in the gasification furnace 2. In a shift reaction reactor 4, carbon oxide contained in the gas coming out of the desulphurisation apparatus 3 is converted to carbon dioxide. A carbon dioxide scrubber 5 serves to remove carbon dioxide contained in the gas coming out of the shift reaction reactor 4. In a denitration apparatus 6, molar ratio of nitrogen to hydrogen in the gas coming out of the carbon dioxide scrubber 5 is brought to about 1:3 by removing nitrogen. Ammonia is obtained as a result of a reaction in generator 7 between nitrogen and hydrogen contained in the gas coming out of the denitration apparatus 6.

EFFECT: invention enables continuous operation of a gasification furnace for a long period of time.
