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。 Study of fouling of monomer recovery system of ESBR plant WANG Jun-zhou 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. 作者简介:王钧周(1954-),男,山东省莱阳市人,高级工程师,现任齐鲁石化股份有限公司橡胶厂副厂长。 参考文献: 收稿日期:1999-12-28 |
