Abstract

A method and arrangement for recovering black liquor chemicals and heat in a sulphate pulp process. The black liquor is concentrated in an evaporation plant, which comprises a pressure heating reactor (12), after which the black liquor is gasified or combusted in a reactor (10) for producing hot gases. The hot gases formed in the reactor (10) are introduced into a gas turbine power plant (16). The exhaust gases from the gas turbine (40) are introduced into a waste heat boiler (52), where steam is generated for a steam turbine power plant (18). Secondary steam is led from the pressure heating reactor as injection steam into the gas turbine.
