METHOD FOR REFINING CARBONYL DIFLUORIDE |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To refine COF<SB>2</SB>from a gaseous mixture composed of COF<SB>2</SB>and CO<SB>2</SB>. <P>SOLUTION: The method for refining carbonyl difluoride has a process of supplying a gaseous mixture containing carbon dioxide (CO<SB>2</SB>) and carbonyl difluoride (COF<SB>2</SB>) to a membrane separator having a polyimide separation membrane and a process of separating the gaseous mixture to the permeation side gaseous CO<SB>2</SB>and the unpermeation side gaseous COF<SB>2</SB>of the membrane separator. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
