关于EDC裂解装置TLE结焦及换热控制问题的探讨

Discussion on coking and heat exchange control of TLE in EDC cracking unit

针对采用美国西方化学技术的EDC裂解装置,分析了在高负荷(设计负荷的105%~110%)运行条件下,影响TLE管侧内壁结焦及换热的主要因素,并总结了对应的控制措施,实施后达到了延长EDC裂解装置良性运行周期的目的。

The main factors affecting the coking and heat transfer efficiency of the inner wall of TLE tubes under high load(105%-110%of design load)were analyzed for the EDC cracking unit using Oxychem technology.Corresponding control measures were summarized to extend the benign operating cycle of the EDC cracking unit.
