| titleOfInvention | The recovery method of epoxides in a kind of tail gas |
| abstract | The invention discloses the recovery method of epoxides in a kind of tail gas, belong to the recovery technology field of epoxides, with the organic amine aqueous solution for absorbing liquid, absorbing liquid cycles through absorption tower, described removal process is: first the tail gas containing epoxides by the gas distributor of bottom, absorption tower, complete an absorption reaction; Tail gas containing epoxides after once absorbing is again by the filler part on top, absorption tower, and absorbed liquid continuous flow upstream washs, and completes double absorption reaction; Tail gas after above-mentioned twice absorption reaction discharges through exhaust apparatus; The present invention is based on the feature that oxirane and organic amine easily react, adopt the organic amine aqueous solution as absorption reaction medium, substitute traditional water, ethylene glycol etc., production technology is simple, reaction condition is gentle, easy to control, and purity is high, and yield is high, and product easily utilizes. |
