Method for supplying regeneration gas to a regeneration zone

Claim 1

A METHOD FOR PROVIDING RELATIVELY LARGE AMOUNTS OF AN OXYGEN-CONTAINING REGENERATION GAS TO A REGENERATION ZONE CONTAINING FLUIDIZED FINELY DIVIDED PARTICLE MATERIAL WHICH COMPRISES RECOVERING OXYGEN-CONTAINING REGENERATION GAS FROM A PLURALITY OF COMPRESSOR ZONES AT A SUITABLY ELEVATED PRESSURE FOR PASSAGE TO A REGENERATION ZONE MAINTAINED AT A PRESSURE ABOVE ABOT 10 P.S.I.G., PASSING SAID OXYGEN-CONTAINING REGENERATION GAS RECIVERED FROM SAID PLURALITY OF COMPRESSION ZONES TO SAID REGENERATION ZONE, RECOVERING A FLUE GAS FROM SAID REGENERATION ZONE AT AN ELEVATED PRESSURE AND A TEMPERATURE ABOVE ABOUT 1000*F., SAID FLUE GAS CONTAINING ENTRAINED FINELY DIVIDED PARTICLE MATERIAL AND CARBON MONOXIDE, RECOVERING SAID FLUE GAS FROM SAID REGENERATION ZONE FOR PASSAGE WITHOUT SUBSTANTIAL COOLING THEREOF TO A PLURALITY OF PARALLEL ARRANGED FINES REMOVAL ZONES, REMOVING FINES FROM SAID FLUE GAS IN SAID FINES REMOVAL ZONES, SEPARATELY RECOVERING FLUE GAS FROM EACH OF SAID FINES REMOVAL ZONES, EACH OF SAID OLURALITY OF COMPRESSION ZONES BEING SEPARATELY CONNECTED TO A FLUE GAS TURBINE ZONE, PASSING A PORTION OF THE FLUES GASES RECOVERED FROM EACH OF SAID FINES REMOVAL ZONES TO EACH OF SAID FLUE GAS TURBINE ZONES UNDER CONDITIONS TO DEVELOP BY EXPANSION OF FLUE GAS THEREIN A MAJOR PORTION OF THE POWER REQUIRED TO DRIVE THE COMPRESSOR ZONE ATTACHED THERETO, REMOVING EXPANDED FLUE GAS FROM EACH OF SAID TURBINE ZONES, COMBINING THE EXPANDED FLUE GASES FROM EACH OF SAID TURBINE ZONES WITH THE REMAINING PORTION OF THE FLUE GASES REMOVED FROM EACH OF THE FINES REMOVAL ZONES, BURNING CARBON MONOXIDE CONTAINED IN THE COMBINED FLUE GASES IN A STEAM GENERATING ZONE, RECOVERING STEAM AT AN ELEVATED TEMPERATURE AND PRESSURE FROM SAID STEAM GENERATING ZONE AND EMPLOYING THE RECOVERED STEAM TO DEVELOP THE REMAINING PORTION OF THE POWER IN THE FORM OF ELECTRICAL ENERGY REQUIRED TO DRIVE THE COMPRESSOR ZONES.
