Embodiment Construction

[0011] In the butadiene rubber production process, the water-oil-gas phase mixture of the top component of the butadiene rubber coagulation kettle passes through the heat exchanger, and the oil after the water (called steam condensate) is separated by the stratified tank enters the storage tank, and then pumped The gas-phase absorption system of the glue tank absorbs butadiene, and the remaining component is recovered solvent oil. These process steps, or the obtaining of reclaiming mineral spirits in other words, are prior art process steps. The treatment and purification of recovered solvent oil are the technical characteristics of the present invention.

[0012] 2~5m 3 / h of steam condensate and 40 ~ 50m 3 The recovered solvent oil per hour enters the static mixer for mixing together, and then enters the airtight container A after mixing, and the oil-water layer is carried out in the container A, and the settled free water carries impurities from the bottom into the sewer,...

Abstract

The 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.

Description

technical field [0001] The invention relates to a process for recovering solvent oil in butadiene rubber production. Background technique [0002] In the production of butadiene rubber, the top fraction of the butadiene rubber coagulation tank is a mixture of water, oil and gas, and the bottom component is butadiene rubber. The water-oil mixture contains utilizable butadiene and solvent oil, which need to be recovered. The recovery process is: 1. The water-oil mixture passes through the heat exchanger to exchange heat; 2. The layered tank separates the water in it, and this part of the water is called steam condensate; 3. The oil layer enters the storage tank and is pumped into the glue The gas phase absorption system of the tank absorbs butadiene, and the oil after recovering butadiene is recovered solvent oil; 4. The recovered solvent oil enters a closed container for oil-water layering, and the settled free water is discharged into the trench, and the upper layer of oil ...
