FIELD: technique for regeneration of energy and chemical products in the process of formation of sulfates and devices for its embodiment. SUBSTANCE: method for regeneration of energy and chemical products is based on the use of gas turbine and compressor, supply of black liquor to gasified reactor in which black liquor is gasified up to pressure above atmospheric one in the presence of some amount of oxygen that results in regeneration of inorganic compounds as liquid phase compounds used for formation of pulp, and energy of organic compounds of black liquor combines mainly with that of chemical compounds of gas phase. Gases formed in gasification and containing sodium compounds are fed to particle cooler in which compounds change into solid state, and gases cooled in particle cooler are cleaned by filter and directed to gas turbine. The device for embodiment of the method is distinguished by the fact that filter is made in form of fibrous filter, and particle cooler is made with fluidized bed and contains mixture of sintered particles of chemical compounds Na2S and Na2CO3 or sand and provided with boiler and evaporator, generator and melt cyclone. EFFECT: considerable increase of level of generation of electricity and steam. 14 cl, 2 dwg
