Elimination of oil plume within regeneration system

Claim 1

IN A PROCESS IN WHICH A GRANULAR CONTACT MATERIAL IS PASSED CYCLICALLY AS A GRAVITATING COMPACT MASS THROUGH A REACTION ZONE WHERE IT IS CONTACTED WITH HYDROCARBONS AT CONVERSION CONDITIONS AND IN WHICH THE SPENT CONTACT MATERIAL IS PASSED THROUGH A REGENERATION ZONE WHERE THE CONTAMINANTS ARE CONTACTED WITH AIR AT SUBSTANTIALLY ATMOSPHERIC PRESSURE TO EFFECT REMOVAL BY BURNING OF CONTAMINANTS AND FURTHER WHERE A SUBSTANTIAL AMOUNT OF PLUME IS FORMED DURING THE REGENERATION CAUSING ATMOSPHERIC POLLUTION, THE IMPROVED METHOD OF PREVENTING CONTAMINATION OF THE AIR COMPRISING: PASSING THE CONTACT MATERIAL THROUGH A LATERALLY CONFINED INLET ZONE IN THE TOP OF THE REGENERATION ZONE, PASSING A STRIPPING GAS THROUGH THE INLET ZONE TO EFFECT REMOVAL FROM THE CONTACT MATERIAL OF PLUME-FORMING VAPORS, PASSING THE VAPORS AND GAS FROM SAID INLET ZONE AS AT LEAST ONE LATERALLY CONFINED STEAM TO A REGION IN THE LOWER PORTION OF THE REGENERATION ZONE WHERE THE TEMPERATURE AND OXYGEN CONCENTRATION ARE ADEQUATE FOR RAPID COMBUSTION OF PLUMEFORMING VAPORS, GRAVITATING THE CONTACT MATERIAL FROM THE INLET ZONE DOWNWARDLY IN THE REGENERATION ZONE THROUGH A BURNING ZONE, INTRODUCING AIR INTO THE BURNING ZONE TO BURN THE CONTAMINANTS FROM THE CONTACT MATERIAL AND ALSO THE PLUME-FORMING MATERIALS TRANSFERRED FROM THE INLET ZONE, WITHDRAWING THE REGENERATED CONTACT MATRIAL FROM THE BOTTOM OF THE REGENERATION ZONE AND RETURNING THE REGENERATED CONTACT MATERIAL TO THE REACTION ZONE FOR RE-USE IN THE PROCESS, AND DISCHARGING THE COMBUSTION GAS FROM THE REGENERATION ZONE TO THE ATMOSPHERE FREE OF PLUME.
