Abstract
A method of compressing carbon dioxide, CO2, including a) generating a stream of high-pressure oxygen gas and a stream of high-pressure hydrogen gas using a high-pressure electrolyser, b) feeding a reciprocating positive displacement pump comprising a reciprocating member, with a stream of CO2, and with the stream of high-pressure oxygen gas as drive gas to actuate the reciprocating member and compress the CO2 to obtain a stream of high-pressure CO2.
Claims15
A method of compressing carbon dioxide, CO2, comprising:
- a) generating a stream of high-pressure oxygen gas and a stream of high-pressure hydrogen gas using a high-pressure electrolyser,
- b) feeding a reciprocating positive displacement pump including a reciprocating member, with a stream of CO2, and with the stream of high-pressure oxygen gas as drive gas to actuate the reciprocating member and compress the CO2 to obtain a stream of high-pressure CO2.
A synthetic hydrocarbon gas production system comprising:
- a high-pressure electrolyser having an oxygen gas outlet and a hydrogen gas outlet, wherein the high-pressure electrolyser is configured to generate a stream of high-pressure oxygen gas discharged through the oxygen gas outlet and a stream of high-pressure hydrogen gas discharged through the hydrogen gas outlet,
- a reciprocating positive displacement pump comprising:
- a CO2 inlet configured to receive a stream of CO2,
- a CO2 outlet,
- a high-pressure gas inlet connected to the oxygen gas outlet, and
- a reciprocating member configured to be actuated by the high-pressure oxygen gas as drive gas and compress the CO2 to obtain a stream of high-pressure CO2 discharged through the CO2 outlet.
