Abstract
Methods and compositions for flocculating solids are provided. The solids may be suspended in an organic liquid medium and a water in oil emulsion may be added to the liquid medium. The water in oil emulsion includes an emulsion polymer capable of flocculating the solids suspended in the organic liquid medium. The emulsion polymer may be added to the organic liquid medium in an inactive form and the polymer may subsequently become activated upon contacting the organic liquid medium. Once activated, the polymer may flocculate the suspended solids.
