METHOD OF ENRICHING CHLORINE GAS |
摘要 |
A method of enriching chlorine gas is described, which method comprises: (a) providing a supported ceramic membrane having a feed side and a permeate side; (b) bringing a feed gas comprising chlorine gas and contaminant gas into contact with the feed side of the ceramic membrane; (c) removing a gaseous permeate depleted in chlorine from the permeate side of the ceramic membrane; and (d) recovering a gas enriched in chlorine from the feed side of the ceramic membrane. The supported ceramic membrane has pore diameters in the range of from 3 angstroms to 12 angstroms. Preferably, the supported ceramic membrane is a substantially cylindrical supported ceramic membrane having a substantially cylindrical internal coaxial passage.
