| titleOfInvention | A kind of method of acetonitrile absorption and separation refinery coking dry gas |
| abstract | The invention discloses a kind of method of acetonitrile absorption and separation refinery coking dry gas.Including：Coking dry gas from refinery's delayed coking unit are compressed and cooling after, using acetonitrile as absorbent, by absorption and desorption twice, then through washing, rich ethane gas product is obtained in second absorption tower tower top, washing column overhead obtains ethylene-rich gas product.The method of the present invention can reduce the olefin(e) centent in rich ethane gas, reach ethane cracking furnace feed needs, and reclaim the ethene component in coking dry gas.Because absorption temperature is more than 5 degree, it is not necessary to ethylene refrigerant and expanding machine, investment is reduced. |
