Abstract
A booster-ejector system captures and recycles leakage fluids from a process. When a pressure differential (head) of the process is above a threshold value, an ejector system uses motive fluid from a process high-pressure (HP) region to entrain and compress the leakage fluid, and direct it to a low pressure (LP) region. When the head is below the threshold value, a controller reconfigures a plumbing system and activates a leakage pump to pump the leakage fluid to the LP region. The system can include only one ejector, or a plurality thereof, which can be coupled such that the diffuser output of each ejector is directed to the suction input of the next ejector. At least one of the ejectors can include an exchangeable throat, which can impart a rotational component to the fluid. The HP and LP regions can be the output and input, respectively, of a compressor.
