Abstract
A gas compression system and method according to which product gas is introduced into and compressed in, a compressor. A portion of the compressed gas is discharged to external equipment, and a portion of the gas is trapped in response to deactivation of the compressor. The trapped gas is passed back to the deactivated compressor.
Claims29
A gas compression system comprising a compressor for receiving product gas and compressing the gas, a first conduit for receiving compressed gas from the compressor, a second conduit for receiving some of the compressed gas and trapping the latter gas when the compressor shuts down, a third conduit connecting the second conduit to the compressor for passing the trapped gas back to the compressor, and a cleaning device disposed in the third conduit for cleaning the trapped gas before it is passed to the compressor.
A gas compression system comprising a compressor having an inlet for receiving product gas and an outlet for discharging the compressed gas;
- a first conduit connected to the outlet for receiving compressed gas;
- a second conduit connected to the first conduit for discharging at least a portion of the gas from the system;
- a third conduit connected to the first conduit for receiving some of the compressed gas and trapping the latter gas when the compressor shuts down;
- a fourth conduit connecting the third conduit to the compressor for passing the trapped gas back to the compressor when the compressor shuts down, and a cleaning device disposed in the fourth conduit for cleaning the trapped gas before it is passed to the compressor.

A gas compression method comprising the steps of introducing product gas into a compressor, activating the compressor for compressing the gas in the compressor, receiving the compressed gas and discharging a portion of the compressed gas to external equipment, recycling a portion of the compressed gas to the inlet of the compressor, trapping a portion of the compressed gas in response to deactivation of the compressor, cleaning the trapped gas, and passing the trapped gas back to the deactivated compressor.
