| titleOfInvention | A kind of refinery's mixing dry gas recovery system and recovery method |
| abstract | The invention discloses a kind of refinery mixing dry gas recovery system and recovery method. Described system comprises: unsaturated dry-gas recovery device, saturated dry-gas recovery device and gasoline absorption plant; Saturated dry-gas recovery device is connected gasoline absorption plant with after the parallel connection of saturated dry-gas recovery device; Unsaturated dry-gas recovery device and saturated dry-gas recovery device comprise separately: compressor, absorption tower, desorber; Gasoline absorption plant comprises: naphtha scrubber, gasoline desorber and flash tank. Oil refinery dry gas divides saturated dry gas and unsaturated dry gas respectively with the recycling of absorption-desorption method, obtains saturated carbon two concentrate gas products and unsaturated carbon two concentrate gas products from desorber tower top, is sent to respectively Furnace of Ethylene Cracking Plant and caustic wash tower. Each absorption tower top gaseous phase is concentrated and is delivered to the unified processing of naphtha scrubber. The inventive method rate of recovery is high, and energy consumption is low, and ethylene unit is moved substantially without impact. |
