    摘要: THE SPECIFIC EMBODIMENTS PROVIDE FOR CONTROLLING A CATALYST SECTION OF A FLUID CATALYST CRACKING SYSTEM BY ADJUSTING THE FLOW RATE OF AN OXYGEN-CONTAINING GAS TO A REGENERATOR IN RESPONSE TO DEVIATION OF THE REGENERATOR DENSE BED TEMPERATURE FROM A PREDETERMINED DENSE BED TEMPERATURE, AND BY ADJUSTING THE PREDETERMINED REGENERATOR DENSE BED TEMPERATURE IN RESPONSE TO A DEVIATION OF THE REACTOR TEMPERATURE FROM A PREDETERMINED REACTOR TEMPERATURE. FURTHER, THE REGENERATED CATALYST FLOW RATE IS ADJUSTED IN RESPONSE TO DEVIATION OF THE FLUE GAS TEMPERATURE FROM A PREDETERMINED FLUE GAS TEMPERATURE.

    摘要: AN IMPROVEMENT IN A PROCESS FOR UTILIZATION OF THE ENERGY CONTENT OF THE FLUE GAS ACCRUED N CATALYTIC CRACKING PLANTS AND FOR THE ECONOMIC CONTROL OF SUCH CRACKING PLANTS, TO THEREBY IMPROVE THE ENTIRE EFFECTIVENESS OF SUCH A PLANT AND ITS ADAPTABILITY TO VARIOUS OPERATING CONDITIONS. THE PROCESS COMPRISES THE STEPS OF SUPPLYING THE COMBUSTION AIR REQUIRED FOR THE REGENERATION OF THE CATALYST TO THE REGENERATOR BY A COMPRESSOR, SUPPLYING THE ACCRUED FLUE GAS TO AN EXHAUST GAS TURBINE BY A CYCLONE BEING INDEPENDENT OF SAID REGENERATOR, SAID EXHAUST GAS TURBINE IS ARRANGED PARTICULARLY TO DRIVE A GENERATOR, BURING THE COMBUSTIBLE PART OF CO CONTAINED IN THE FLUE GAS IN A CATALYTIC CO BOILER FOLLOWING THE TURBINE, SUPPLYING THE SURPLUS AIR RESULTING FROM A SLIGHTER REQUIREMENT OF COMBUSTION AIR FOR HEATING TO SAID CO BOILER BY MEANS OF A LINE (BYPASS LINE) LEADING PAST THE CRACKING PROCESS AND BRANCHING OFF BETWEEN SAID COMPRESSOR AND SAID REGENERATOR AND MIXING SAID SURPLUS AIR TO THE FLUE GAS COMING FROM THE REGENERATOR BEFORE SAID CYCLONE.
