摘要
真空过滤系统是酮苯脱蜡工艺的核心单元,过滤机效率、温洗操作效果对平稳运行和产品收率具有很大影响.文章对酮苯过滤系统自控方面存在的问题进行了分析,提出了对过滤机温洗程序优化改造的措施,实现了过滤机全自动一键温洗,可显著改善过滤机温洗效果和质量,避免了人为操作失误,大幅度降低了人工劳动强度,提高了装置平稳率、产品质量合格率,油蜡综合收率增加0.7％;同时实现了安全气密闭压力的平稳控制,避免安全气携带溶剂排空,减少了溶剂损失和环境污染,取得良好的经济和环保效益.
Abstract
The vacuum filtration system is the core unit of the ketone-benzene dewaxing process.The efficiency of the fil-ter and the effect of warm washing operation have a great impact on smooth operation and product yield.The paper analy-zes the problems existing in the automatic control of the ketone-benzene filtration system,and proposes measures to opti-mize the warm washing program of the filter,realizing fully automatic one-key warm washing of the filtration machine.This significantly improves the washing effect and quality,reduces human errors,and reduces manual labor intensity.The stability rate of the unit,product qualification rate are significantly improved,and the comprehensive yield of oil wax in-creased by 0.7％,realizing the stable control of the sealing pressure of the safety gas at the same time,avoiding safe gas carrying solvent empty.It also reduces solvent discharge losses,achieving good economic and environmental benefits.
