ABSTRACT:
The invention relates to a method and an equipment for the recovery of energy and chemicals in a sulphate process, wherein black liquor is passed into a gasification reactor (3) in which it is gasified at a pressure above the atmospheric pressure in the presence of an amount of oxygen smaller than the stoichiometric amount, whereby inorganic compounds are recovered as liquid-phase compounds useable in the present pulping process, and the energy of the organic compounds of black liquor is bound mainly to the chemical compounds of the gas phase. Gases formed in the gasification, containing sodium compounds, are passed into a particle cooler (4), in which the compounds are brought into solid state. Gases cooled in the particle cooler (4) are purified by a filter (5) and then passed into a gas turbine (7).
