| titleOfInvention | Purge gas and carbon four-residue comprehensive recovery system in butadiene production |
| abstract | The utility model discloses a recovery system is synthesized to purge gas and four residual of carbon in butadiene production, including four raw materials buffer tanks of carbon, first rectifying column backward flow jar, second rectifying column backward flow jar, butene raw materials buffer tank, air compressor machine, steam source, dehydrogenation reactor, water-cooling acid washing tower, compressor, oil absorption tower, absorption oil desorption tower, first extraction rectifying column, second extraction rectifying column, crude butadiene water washing tower, butadiene dehydration tower, butadiene rectifying column and recovery rectifying column. According to the scheme, the recovery rectifying tank is arranged, heavy component butene-1, cis-butene and isobutane in the carbon four raffinate and purge gas are returned to the butylene raw material buffer tank of the oxidative dehydrogenation unit to be used as oxidative dehydrogenation raw materials, the light component is discharged to a torch to be combusted, the utilization rate of the carbon four raw material is improved, the energy-saving and emission-reduction effect of the device is obvious, and the economic benefit is obvious. |
