ABSTRACT:
It has been found that solvent residues can be removed from aqueous paper pulps by stripping with economic volumes of gases. This can be done in conventional contacting equipment without reducing pulp consistencies below the levels typical of commercial paper-making operations. The solvents stripped out are recoverable and do not constitute a source of pollution.
