Claim 1

A METHOD OF RECOVERY OF HIGH YIELDS OF CLEAN GAS-OIL HEAVY RESIDUAL HYDROCARBON OIL WHICH COMPRISES GRAVITATING A BED OF PACKING DOWNWARDLY INTO AND THROUGH A STRIPPING AND RECTIFICATION ZONE; INTRODUCING SAID HEAVY RESIDUAL HYDROCARBON OIL INTO SAID GRAVITATING BED OF PACKING INTERMEDIATE ITS ENDS; DISTRIBUTING SAID HEAVY RESIDUAL HYDROCARBON OIL THROUGH SAID GRAVITATING BED OF PACKING; INTRODUCING STEAM INTO THE LOWER END OF SAID GRAVITATING BED OF PACKING AT A TEMPERATURE SUFFICIENTLY HIGH TO VAPORIZE AT LEAST A PORTION OF SAID HEAVY RESIDUAL HYDROCARBON OIL FROM THE SURFACE OF SAID PACKING; PASSING SAID STREAM AND VAPORIZED HYDROCARBON UPWARDLY THROUGH AND IN DIRECT HEAT EXCHANGE WITH SAID BED OF PACKING; REMOVING OVERHEAD A MIXTURE OF STEAM AND CLEAN GAS-OIL VAPORS; CONDENSING SAID STEAM AND SAID GAS-OIL VAPORS; SEPARATING SAID GAS-OIL AND WATER RESULTING FROM THE CONDENSATION; RECYCLING A PORTION OF THE RECOVERED GAS-OIL TO THE TOP OF SAID GRAVITATING BED OF PACKING AS REFLUX; CONTINUOUSLY GRAVITATING SAID PACKING FROM SAID STRIPPING AND RECTIFYING ZONE AT A RATE OF 0.1 TO 0.5 LINEAR FOOT PER MINUTE; BURNING CARBONACEOUS DEPOSITS FROM THE SURFACE OF SAID PACKING GRAVITATED FROM SAID STRIPPING AND RECTIFYING ZONE BY CONTACTING SAME WITH AIR IN A COMBUSTION ZONE; PASSING RESULTING COMBUSTION PRODUCTS AND SAID HEAVY RESIDUAL HYDROCARBON OIL FEED IN AN INDIRECT HEAT EXCHANGE PRIOR TO THE INTRODUCTION OF THE RESIDUAL OIL INTO THE STRIPPING AND RECTIFYING ZONE; GRAVITATING THE RESULTING HOT CLEAN PACKING FROM SAID COMBUSTION ZONE THROUGH A STREAM PRODUCING ZONE; CONTACTING WATER WITH SAID HOT CLEAN PACKINGS IN A DIRECT HEAT EXCHANGE SO AS TO CONVERT SAID WATER TO STEAM; REMOVING SAID STEAM FROM SAID STEAM PRODUCING ZONE AND INTRODUCING SAID STEAM INTO THE LOWER END PORTION OF SAID STRIPPING AND RECTIFYING ZONE AT A TEMPERATURE IN THE RANGE OF 700 TO 750* F., GRAVITATING RESULTING COOLED PACKING FROM THE LOWER END OF SAID STEAM PRODUCING ZONE; AND ELEVATING SAID COOLED PACKING TO TOP OF SAID STRIPPIN AND RECTIFYING ZONE.

Claim 2

A METHOD OF RECOVERY OF HIGH YIELDS OF CLEAN GAS-OIL HEAVY RESIDUAL HYDROCARBON OIL WHICH COMPRISES GRAVITATING A BED OF PACKING DOWNWARDLY INTO AND THROUGH A STRIPPING AND RECTIFICATION ZONE; INTRODUCING SAID HEAVY RESIDUAL HYDROCARBON OIL INTO SAID GRAVITATING BED OF PACKING INTERMEDIATE ITS ENDS; DISTRIBUTING SAID HEAVY RESIDUAL HYDROCARBON OIL THROUGH SAID GRAVITATING BED OF PACKING; INTRODUCING STEAM INTO THE LOWER END OF SAID GRAVITATING BED OF PACKING AT A TEMPERATURE SUFFICIENTLY HIGH TO VAPORIZE AT LEAST A PORTION OF SAID HEAVY RESIDUAL HYDROCARBON OIL FROM THE SURFACE OF SAID PACKING; PASSING SAID STREAM AND VAPORIZED HYDROCARBON UPWARDLY THROUGH AND IN DIRECT HEAT EXCHANGE WITH SAID BED OF PACKING; REMOVING OVERHEAD A MIXTURE OF STEAM AND CLEAN GAS-OIL VAPORS; CONDENSING SAID STEAM AND SAID GAS-OIL VAPORS; SEPARATING SAID GAS-OIL AND WATER RESULTING FROM THE CONDENSATION; RECYCLING A PORTION OF THE RECOVERED GAS-OIL TO THE TOP OF SAID GRAVITATING BED OF PACKING AS REFLUX; CONTINUOUSLY GRAVITATING SAID PACKING FROM SAID STRIPPING AND RECTIFYING ZONE AT A RATE OF 0.1 TO 0.5 LINEAR FOOT PER MINUTE; BURNING CARBONACEOUS DEPOSITS FROM THE SURFACE OF SAID PACKING GRAVITATED FROM SAID STRIPPING AND RECTIFYING ZONE BY CONTACTING SAME WITH AIR IN A COMBUSTION ZONE; PASSING RESULTING COMBUSTION PRODUCTS AND SAID HEAVY RESIDUAL HYDROCARBON OIL FEED IN AN INDIRECT HEAT EXCHANGE PRIOR TO THE INTRODUCTION OF THE RESIDUAL OIL INTO THE STRIPPING AND RECTIFYING ZONE; GRAVITATING THE RESULTING HOT CLEAN PACKING FROM SAID COMBUSTION ZONE THROUGH A STREAM PRODUCING ZONE; CONTACTING WATER WITH SAID HOT CLEAN PACKINGS IN A DIRECT HEAT EXCHANGE SO AS TO CONVERT SAID WATER TO STEAM; REMOVING SAID STEAM FROM SAID STEAM PRODUCING ZONE AND INTRODUCING SAID STEAM INTO THE LOWER END PORTION OF SAID STRIPPING AND RECTIFYING ZONE AT A TEMPERATURE IN THE RANGE OF 700 TO 750* F., GRAVITATING RESULTING COOLED PACKING FROM THE LOWER END OF SAID STEAM PRODUCING ZONE; AND ELEVATING SAID COOLED PACKING TO TOP OF SAID STRIPPIN AND RECTIFYING ZONE.
