Zusammenfassung:	In a method of processing cellulose pulp, which is produced by digesting from softwood or hardwood chips in a digester (1), the digested pulp is washed, the washed pulp is processed in an oxygen stage, and the pulp is further washed and bleached in a bleaching plant. Soap and gas and/or other light materials produced in the digesting process are separated from a filtrate and/or from black liquor by means of a pressurized separation apparatus (16, 22, 48, 49, 52) such as a hydrocyclone, a centrifuge or a pump.
