丁苯橡胶装置单体回收系统堵挂问题探讨

王钧周

  摘要:介绍了齐鲁引进乳聚丁苯橡胶装置回收单 元存在的设备堵挂问题,经分析认为歧化松 香酸钾中带有含共轭双键的松香酸钾,脂肪酸中C16-18组分含量高,DEMOL缩合度 高于5的组分高,反应转化率高于72%是造成堵挂的4条主要原因,提出了对策。

ABSTRACT

  The fouling of monomer recovery system of Qilu ESBR plant was studied.It was con sidered that the fouling was principally caused b y the following four reasons;There existed the colopholic potassium containing c onjugated doublebonds in the disproportionated colopholic potassium;excessive co ntent of C16-18 compositions existed in the fatty acid;excessive content of com positions for which the DEMOL condensation degree was above 5;the reaction conve rsion was higher than 72 percent.Effective countermeasures were proposed.
  Key words:SBR;monomer recovery;fouling;study;reaction;lat ex stability
