Abstract
<PICT:0986510/C4-C5/1> Energy is recovered from spent hot regenerator gases from a catalytic cracking unit from which gases catalyst has been removed by burning at their superatmospheric pressure in a high pressure steam boiler together with extra fuel and air after which the combustion gases from the boiler at a controlled temperature are expanded in at least one gas turbine/compressor unit, the compressor(s) of which supplies combustion air for the regenerator and the boiler. The temperature of gases entering the turbine is controlled to prevent damage to the blades which would occur if the temperature were too high and maintain the output of the turbines which would drop if the temperature were too low. Spent gases from regnerator 1 are passed through a cyclone 5 or other separator and then into a combustion section 8 of steam boiler 7 together with air from line 12 and a fuel/air mixture in burner 13. Steam is produced in section 9 at about 50 atmospheres and can be expanded to the normal 18 atmospheres in gas turbine/compressor units supplying gases to the cracking unit. The temperature of the gases is adjusted before leaving the boiler in section 10 by adding heat by burning fuel in burner 18 or cooling by adding water from spray 19 automatically controlled by controllers 23 responsive to the temperature in line 20. Turbine/compressor 31/32 provides air for the regenerator 1; the amount is automatically controlled by adjustment of excess flowing through valve 43 which is passed to line 46 together with the output of turbine/compressor 29/30 to supply air for the boiler. Heat is recovered in heat exchanger 37 which preheats the water feed to the boiler. Pressure in the regenerator is controlled by control of valve 50 or valve 48.
