Abstract:
A high pressure gas compression system comprising:a gas source with a gas supply;a high pressure piston compressor having a cylinder with a reciprocating piston in part forming a compression chamber, the reciprocating piston having cycle phases including a compression phase and an expansion phase;a first compressed gas storage tank having pressure control means for controlling the pressure in the first tank at a first pressure;a second compressed gas storage tank having pressure control means for controlling the pressure in the second tank at a second pressure lower than the first pressure;a central electronic control module electronically connected to the pressure control means of the first storage tank and to the pressure control means of the second storage tank;an electro-hydraulic valve system with a first electro-hydraulic valve electronically connected to the control module with valve means for admitting gas to the compression chamber on actuation by the control module;a second electro-hydraulic valve, electronically connected to the control module with valve means for passing compressed gas from the compression chamber to the second tank on actuation by the control module;a third electro-hydraulic valve, electronically connected to the control module with valve means for passing compressed gas from the compression chamber to the first tank on actuation by the control module, and a valving device with valve means for passing compressed gas at the first pressure through the compression chamber to the second storage tank to scavenge the compression chamber.
