Abstract:
A process for the separation of solids from hydrocarbons and water mixtures comprising:feeding a stream containing liquid hydrocarbons, water and particulate solids in a first ratio of solids to liquids to a porous tubular metal zone, under pressure conditions and at a velocity to prevent solids from adhering to the porous metal structure,separating a first liquid portion comprising said hydrocarbons and water from the solid particles by passing said first liquid portion through said porous metal zone into a nonporous tubular zone surrounding said porous tubular structure,separating said water and hydrocarbons into two phases in said nonporous tubular zone,recovering said water and hydrocarbons of said first liquid portion from said nonporous tubular zone as separate streams andpassing a second liquid portion containing said particulate solids in a second ratio of solids to liquids from said porous tubular zone.
