Abstract
Den foreliggende oppfinnelse vedrører blandinger og fremgangsmåter for behandling av harpiksavsetningsproblemer i kjemisk papirmasse ved å behandle prosessvann for kjemisk papirmasse med en kombinasjon av en lipase og en peroksidkilde. Den foreliggende oppfinnelse vedrører også blandinger og fremgangsmåter for behandling av harpiksavsetningsproblemer i kjemisk papirmasse ved å behandle prosessvann for kjemisk papirmasse med en lipase, en peroksidkilde og en eller flere organiske syrer.The present invention relates to compositions and methods for treating resin deposition problems in chemical pulp by treating chemical pulp process water with a combination of a lipase and a peroxide source. The present invention also relates to compositions and methods for treating resin deposition problems in chemical pulp by treating process water for chemical pulp with a lipase, a peroxide source and one or more organic acids.
