| 摘要 |
The invention relates to a method for the purification/separation/enrichment of a gas or biogas that contains methane and carbon dioxide. The gas (200) is processed by a spirally constructed coil pump (20) together with a liquid (65) by alternating dosing in such a manner that the coil pump is alternately supplied with liquid and gas that leave the coil pump (20) after a pressure build-up and are conducted to a gas separator (30) from which the gas is conducted as needed to a liquid scrubber (40) for continued purification before the gas is transported to a usage site. The liquid in the gas separator is conducted to a stripper tower (50) for the removal of carbon dioxide, after which the liquid is conducted to a liquid tank (60) for being reused in the method/process. |
