Solids removal process
Abstract
Abstract A PROCESS FOR THE REMOVAL OF SOLIDS FROM A VISCOUS HEAVY HYDROCARBON STREAM SUCH AS PETROLEUM RESIDUUM. THE PROCESS INCLUDES THE STEP OF ADJUSTING THE TEMPERATURE OF A POROUS BED UNTIL THE STREAM CAN FLOW THERETHROUGH WITHOUT ANY SIGNIFICANT CONDENSATION OF DISSOLVED OR ENTRAINED WATER. THE SOLIDS CONTAINING STREAM IS PASSED THROUGH THE POROUS BED WHICH BED IS FORMED OF HARD GRANULAR SPHEROIDAL PARTICLES. THESE PARTICLES ARE SUBSTANTIALLY UNIFORM IN SIZE AND OF A RIGID AND SUBSTANTIALLY INCOMPRESSIBLE DIELECTRIC MATERIAL. AN ELECTRIC FILED IS ESTABLISHED WITHIN THE POROUS BED HAVING AN INTENSITY OF AT LEAST 5 KILOVOLTS PER INCH OF DC POTENTIAL. THE ELECTRIC FIELD CAUSES THE REMOVAL OF SOLIDS FROM THE STREAM AND THEIR TENACIOUS ADHESION TO THE PARTICLES. THE STREAM WITH REDUCED SOLIDS CONTENT IS ,: REMOVED FROM THE POROUS BED TO A SUBSEQUENT UTILIZATION. THE PARTICLES ARE PERIODICALLY CLEANED OF THE ACCUMULATED SOLIDS TO RESTORE THE SOLIDS-REMOVAL EFFICIENCY OF THE POROUS BED.
