AbstractThe present invention is solvent oil recovering process in butadiene rubber production. The gaseous water-oil mixture from the top of butadiene rubber coacervating reactor, after its butadiene is recovered, is recovered to obtain solvent oil through oil and water demixing and purification of the oil layer in dewatering tower system. The present invention features that the mixture is first mixed with water, then demixed to separate oil and water layer, and the oil layer is finally purified in a dewatering tower. The said process can eliminate impurities, reduce the corrosion and chocking in the recovering apparatus and prolong operation period between overhauls, so that the present invention has relatively high industrial application value.
