摘要： Disclosed is a third stage separator which includes two main clean gas outlets. One main clean gas outlet communicates with a power recovery unit such as an expander turbine while the second main clean gas outlet communicates with a conduit that bypasses the expander turbine. The present invention avoids use of the extra equipment, engineering and installation labor required to prevent the bypass conduit from placing a force load on the line to the power recovery unit.

摘要： A system and method are provided for recovering power from hot flue gas of a catalyst regenerator in an FCC unit and an integrated fluid catalytic cracking steam pressure letdown. The system includes a flue gas power recovery system including an expander and a turbine for generating power by letting down steam from a higher pressure to a lower pressure for use in a refinery process such as an FCC unit.
