一种丁苯橡胶苯乙烯回收工艺,其特征在于:来自丁二烯闪蒸罐(1)、滗析器(10)的水相和苯乙烯汽提塔(3)侧线抽出的水进入缓冲罐(2),由废水汽提塔进料泵(5)部分送至废水精制装置(6),另一部分送至苯乙烯汽提塔的1号塔盘,然后从3号或4号塔盘侧线抽出;由胶乳进料泵(4)送来的胶乳进入苯乙烯汽提塔的5号或6号塔盘,蒸汽自塔体下部的蒸汽源(8)加入,脱气后的胶乳由塔体底部用泵送往胶乳储 A styrene-butadiene styrene styrene recovery process is characterized in that the water extracted from the butadiene flash tank (1), the water phase of the decanter (10) and the side strip of the styrene stripper (3) enters a buffer tank (2) is sent to the waste water refining unit (6) from the part of the waste water stripper feed pump (5) and the other part to the tray 1 of the styrene stripper, and then from the tray of line 3 or 4 (4) into the styrene stripping tower No. 5 or 6 trays, steam from the lower part of the tower body steam source (8) to join the degassed latex from the tower body Bottom pump to latex storage
