Liquor removal from particulate solids such as wet wood pulp is achieved by applying a pneumatic or vapour pressure for- ce through a pad of the wood pulp to compress the solids and to expel liquor from the solids. If air is used as a displacing medi- um, no wash liquor is added and the solids are simply compressed and some of the liquor is replaced by the gas passing through the suspension. If steam is used, not as a heating medium but as a pressure medium, an increase in liquor removal occurs over and above that removed by gas only due to the condensation of the steam to form a liquid front travelling before the steam through the solid suspension. Hence, in principle, a combination of pressure washing and diplacement occurs resulting in a high efficiency in washing. Gas or steam could therefore simply be applied to any conventional operation to increase the washing effi- ciency both by compression and by displacement
