Abstract
1,003,517. Steam and gas turbine plant; generating combustion products under pressure. PULLMAN Inc. Nov. 27, 1961, No. 42286/61. Headings F1G and F1L. [Also in Division B1] In the supply of regeneration gases to a regeneration zone, a method of utilizing flue gases recovered from the regeneration zone comprises recovering the flue gases at an elevated temperature, removing finely divided particle material from the gases, expanding the gases in a turbine to provide power to drive a compressor which compresses regeneration gas to a suitable elevated pressure for passage to the regeneration zone, and recovering the expanded flue gases from the turbine at an elevated temperature for the generation of steam employed in a steam turbine to provide a portion of the power required to drive the compressor. Coke is burnt in a regenerator 22 to burn off carbonaceous deposits on a fluidized catalyst material 20. The resulting flue gases are passed through cyclone separators 28, 30 wherein some of the entrained catalyst particles are removed, and then divided into two substantially equal streams leading to further separators 56, 58 which reduce the catalytic content to about 30 p.p.m., preferably 15-30 p.p.m. The gases are then supplied, at a temperature of about 1,050 F. and a pressure of about 29 p.s.i.a., to turbines T2, T3 which develop a major portion of the power required to drive compressors C1, C2. Cooling steam or water may be introduced into the flue gases through conduits 64, 66. A portion of the flue gases may by-pass the turbines through conduits 76, 78 fitted with valves. The gases exhausted from the turbines, at a temperature of about 885‹F. and a pressure of about 16À2 p.s.i.a., are supplied to a boiler 74 in which CO in the flue gases is burned to produce steam which is supplied through conduits 82, 92, 94 to drive turbines T1, T4 providing the remainder of the power required to drive the compressors C1, C2. Alternatively, the steam turbines may be used to develop electrical power and an electric motor used to provide the make-up power.
