PROCESS FOR DEHYDRATION OF A GAS CONTAINING HYDROCARBONS |
摘要 |
In a process for the dehydration of gases by permeation through a membrane of selective permeability, the membrane comprises a bundle of hollow fibres based on polymers and open at both ends, the methane permeability of which is at least 10-5 cm3/cm2.s.cm Hg and the water/methane selectivity factor of which is greater than about 100. The gas to be dehydrated is supplied under pressure to a chamber through which the fibres extend and water-enriched gas is withdrawn from the interiors of the fibres. The fibres have internal diameters of between 0.1 mm and 0.5 mm, lengths of between 0.5 m and 3 m and thicknesses of between 0.05 mm and 0.3 mm, the thickness of the active layer of the membrane being less than 1 mu m. |
