A method for removing hydrogen sulphide ions (HS) from a liquor () of a pulp mill process, the method comprising pumping the liquor () to an injector arrangement () using a pump arrangement () such that the pumping of the liquor () through a jet nozzle () generates suction at a gas inlet (), whereby reagent gas () is mixed with the liquor (), and letting out the treated liquor () from the injector arrangement () to a vessel (). In this way, the liquor () is treated to form at least partly treated liquor (). A corresponding use of an injector arrangement. A system for performing the method.

A method and an apparatus for processing wood chips, wherein the wood chips are treated with steam in a gas removal apparatus. The condensate formed in the gas removal apparatus is removed from the gas removal apparatus and the wood chips are treated with a processing solution in order to remove metal ions from the wood chips. Condensate formed in the gas removal apparatus is used as processing solution.

Method and apparatus for reducing the amount of sludges produced in a pulp and/or paper mill. The sludge produced in a pulp and/or paper mill as a result of waste water treatment is conveyed to solid fuel and the produced fuel-sludge mixture is burned in a power boiler. The solid fuel is heated before sludge is mixed therein.
