Abstract (en)
[origin: GB2487790A] A gas compressor comprises an expandable liquid-filled bag 10 inside a pressure vessel 4. Filling and expanding the bag compresses a gas inside the pressure vessel, but outside the bag. The liquid is supplied from a tank 16 via a high pressure pump 21. Monitoring and control devices are provided for pressure, temperature, flow rate and fluid level. A nitrogen gas purging valve 8 may be provided. The liquid may be water or a hydraulic fluid. The gas may be hydrogen. The bag may be made of any flexible or composite material such as reinforced rubber or fibre reinforced plastic. As an alternative, the bag may be replaced with a mechanical piston inside the vessel, the piston being driven by liquid. As a further alternative, the liquid may be in direct contact with the gas, the rising column of liquid acting as a piston.
