Process and apparatus for pressure and temperature control system

Claim 2

IN A HYDROCARBON CONVERSION SYSTEM WHEREIN THE CATALYST WITHIN A CONVERSION ZONE IS ALTERNATELY ON PROCESS AND ON REGENERATION AND WHEREIN HOT COMBUSTION GASES FROM A COMBUSTION ZONE ARE PASSED TO SAID CONVERSION ZONE, CIRCULATED IN A CYCLE WITHIN SAID CONVERSION ZONE AROUND A FRIST END PORTION AND THEN AROUND THE OTHER AND PORTION OF A CATALYST BED THEREIN, AND WITHDRAW FROM SAID CONVERSION ZONE, AND WHEREIN IT IS DESIRED TO PROTECT THE WALLS OF SAID COMBUSTION ZONE FROM EXCESSIVE TEMPERATURES, THE IMPROVEMENT WHICH COMPRISES: CONTROLLING THE AMOUNT OF FUEL BURNED IN SIAD COMBUSTION ZONE RESPONSIVE TO THE TEMPERATURE WITHIN SAID CONVERSION ZONE, AND SEPARATELY CONTROLLING THE WITHDRAWAL OF SAID GASES FROM SAID CONVERSION ZONE RESPONSIVE TO THE TEMPERATURE OF A WALL OF SAID COMBUSTION ZONE BY WITHDRAWING MORE OF SAID GASES FROM SAID CONVERSION ZONE AND ADMITTING MORE EXCESS AIR INTO SAID COMBUSTION ZONE WHEN SAID WALL TEMPERATURE INCREASES AND WITHDRAWING LESS OF SAID GASES FROM SAID CONVERSION ZONE AND ADMITTING LESS EXCESS AIR INTO SAID COMBUSTION ZONE WHEN SAID WALL TEMPERATURE DECREASES.

Claim 3

APPRARTUS FOR CARRYING OUT CHEMICAL REACTIONS WHICH COMPRISES, IN COMBINATION: A HOUSING, A CATALYST TUBE POSITIONED WITHIN SAID HOUSING, A FURNACE COMMUNICATING WITH ONE END OF SAID HOUSING FOR SUPPLYING HOT COMBUSTION GASES TO SAID HOUSING, MEANS WITHIN SAID HOUSING FRO CIRCULATING SAID COMBUSTION GASES IN A CYCLE AROUND A FIRST END PORTION AND THEN AROUND A SECOND THE PORTION O SAID CATALYST TUBE, AN EXHAUST CONDUIT AT THE OPPOSITE END OF SAID HOUSING, FLOW CONTROL MEANS IN SAID EXHAUST CONDUIT, FUEL INLET MEANS FOR SUPPLYING FUEL TO SAID FURNACE, AIR INLET MEANS FOR SUPPLYING COMBUSTION AIR AND EXCESS AIR TO SAID FURNACE, A FIRST TEMPERATURE SENSING MEANS WITHIN SAID HOUSING, TEMPERATURE CONTROL MEANS CONNECTED TO SAID FIRST TEMPERATURE SENSING MEANS AND OPERATIVELY CONNECTED TO SAID FUEL INLET MEANS FOR CONTROLLING THE AMOUNT OF FUEL SUPPLIED TO SAID FURNACE RESPONSIVE TO THE TEMPERATURE WITHIN SAID HOUSING, A SECOND TEMPERATURES SENSING MEANS POSITIONED IN A WALL OF SAID FURNACE, PRESSURE CONTROLLING MEANS CONNECTED SAID SECOND TEMPERATURE SENSING MEANS AND OPERATIVELY CONNECTED TO SAID FLOW CONTROL MEANS IN SAID EXHAUST CONDUIT FOR CONTROLLING THE AMOUNT OF SAID COMBUSTION GASES WITHDRAWN FROM SAID HOUSING AND ADTHE TEMPERATURE OF SAID WALL OF SAID FURNACE BY WITHDRAWING MORE OF SAID GASES FROM SAID HOUSING AND ADMITTING MORE EXCESS AIR INTO SAID FURNACE WHEN SAID WALL TEMPERATURE INCREASES AND WITHDRAWING LESS OF SAID GASES FROM SAID HOUSING AND ADMITTING LESS EXCESS AIR INTO SAID FURNACE WHEN WALL TEMPERATURE DECEASES.

Claim 4

APPRARTUS FOR CARRYING OUT CHEMICAL REACTIONS WHICH COMPRISES, IN COMBINATION: A HOUSING, A CATALYST TUBE POSITIONED WITHIN SAID HOUSING, A FURNACE COMMUNICATING WITH ONE END OF SAID HOUSING FOR SUPPLYING HOT COMBUSTION GASES TO SAID HOUSING, MEANS WITHIN SAID HOUSING FRO CIRCULATING SAID COMBUSTION GASES IN A CYCLE AROUND A FIRST END PORTION AND THEN AROUND A SECOND THE PORTION O SAID CATALYST TUBE, AN EXHAUST CONDUIT AT THE OPPOSITE END OF SAID HOUSING, FLOW CONTROL MEANS IN SAID EXHAUST CONDUIT, FUEL INLET MEANS FOR SUPPLYING FUEL TO SAID FURNACE, AIR INLET MEANS FOR SUPPLYING COMBUSTION AIR AND EXCESS AIR TO SAID FURNACE, A FIRST TEMPERATURE SENSING MEANS WITHIN SAID HOUSING, TEMPERATURE CONTROL MEANS CONNECTED TO SAID FIRST TEMPERATURE SENSING MEANS AND OPERATIVELY CONNECTED TO SAID FUEL INLET MEANS FOR CONTROLLING THE AMOUNT OF FUEL SUPPLIED TO SAID FURNACE RESPONSIVE TO THE TEMPERATURE WITHIN SAID HOUSING, A SECOND TEMPERATURES SENSING MEANS POSITIONED IN A WALL OF SAID FURNACE, PRESSURE CONTROLLING MEANS CONNECTED SAID SECOND TEMPERATURE SENSING MEANS AND OPERATIVELY CONNECTED TO SAID FLOW CONTROL MEANS IN SAID EXHAUST CONDUIT FOR CONTROLLING THE AMOUNT OF SAID COMBUSTION GASES WITHDRAWN FROM SAID HOUSING AND ADTHE TEMPERATURE OF SAID WALL OF SAID FURNACE BY WITHDRAWING MORE OF SAID GASES FROM SAID HOUSING AND ADMITTING MORE EXCESS AIR INTO SAID FURNACE WHEN SAID WALL TEMPERATURE INCREASES AND WITHDRAWING LESS OF SAID GASES FROM SAID HOUSING AND ADMITTING LESS EXCESS AIR INTO SAID FURNACE WHEN WALL TEMPERATURE DECEASES.
