Abstract: Process for gasification of an alkali containing energy rich aqueous solution (120) from a pulp mill in an entrained flow gasification reactor (2), the process comprising the steps of d) Supplying said alkali containing energy rich aqueous solution (120) to said gasification reactor (2), e) Gasifying said alkali containing energy rich aqueous solution (120) in the reactor (2) by using an oxidizing medium at sub-stoichiometric conditions and at a temperature below 1400 C in an outlet of said reactor (2); and, f) Producing a phase of a liquid material and a phase of a gaseous material in said reactor (2). wherein in step (a) supplying a bio-oil (110) to said gasification reactor (2), in step (b) simultaneously gasifying said alkali containing energy rich aqueous solution (120) and said bio-oil (110) in the reactor (2).

Abstract: Method for recovering chemicals and energy from sulphite thick liquor containing organic and inorganic compounds obtained when producing pulp by chemical delignification of fibrous raw material using a sulphite pulping process, the method including processing of the organic and inorganic compounds at a global temperature above 800° C. whereby producing partly at least one phase of a liquid material and partly at least one phase of a gaseous material. The processing is carried out by gasification of the sulphite thick liquor in a gasification reactor at sub-stoichiometric conditions and in the presence of an oxidizing medium. The reactor has an opening in its bottom in the form of a chute which opens directly into a quench compartment.
