苯乙烯储罐防聚合控制措施及效果

摘要

针对齐鲁储运厂苯乙烯储存过程中出现的聚合现象，以142＃储罐为例，采用联合研发的延缓苯乙烯聚合的新型储罐内防腐涂料及施工工艺，同时对原氮封系统进行了改造。4 a 多的实际运行结果表明，142＃储罐罐体及储罐的死角（透光孔）等部位均未发现聚合物，阻聚效果明显；142＃储罐内苯乙烯产品的质量达到指标要求，且延长了苯乙烯储罐清罐周期，具有良好的经济和环境效益。%Aimed at polymerization phenomenon existing storage course of styrene in Qilu Storage & Transportation Complex, taken No.142 storage tank as an example, the original nitro-gen sealing system was reformed by combined technologies of adopting new type anticorrosive coating in the storage tank and construction process.The practical running results in more than 4 yeas showed that no polymer was found in shell and dead space (light hole) of the No.142 stor-age tank, inhibition was obviously obtained.Product quality of styrene in the No.142 storage tank met index requirements, and tank clean period was prolonged.Good economic and envi-ronmental profits were obtained.
