A liquid solid separation apparatus having a porous metal pipe sealed inside a non-porous metal pipe which allows a portion of the liquids, e.g., hydrocarbons and water to pass through the first pipe into the non porous pipe from which they are removed while solids are retained within the porous pipe. In the process there is a system pressure which aids in the filtration and a circulating velocity which removes the detained solids. Preferably a portion of these solids with reduced liquid content are recycled back to the system, mixed with fresh feed. By recycling a porion of the recovered solid concentrate the velocity of the flow in the system kept constant and the system itself is stabilized.

[ What is claimed is:] [1.] 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.
