DEVICE FOR MAKE-UP OF SPECIAL PURE AND DRY TEST GAS MIXTURES OF METHANE, PROPANE, CARBON MONOXIDE IN HIGH-PRESSURE VESSELS WITH VOLUME FROM TWO UP TO FORTY LITRES Russian patent published in 2016 - IPC B01F3/20 

FIELD: oil and gas industry.

SUBSTANCE: device for make-up of special pure and dry test gas mixtures of methane, propane, carbon monoxide in high-pressure vessels with volume from 1 up to 40 litres comprised of compressor, a vessel with 100% tested gas, operating and reference cylinders for test gas mixture (TGM), instruments to measure concentration and moisture of the mixed up component in the test mixture in high-pressure working vessel for preparation, set of stop valves and main block valves. Between high-pressure vessel with 100% tested gas and operating cylinder as well as at input of incoming gas in-flow air driers and fine particle filters are coupled constructively to the compressor.

EFFECT: make-up of test gas mixtures with minimum permitted concentration of moisture less than 5% and fine particles less than 0,01 mcm.
