摘　　要：通过流程模拟计算石蜡除嗅装置中的石蜡嗅味物质含量,并结合文献报道数据及工业装置运行结果,确定石蜡嗅味物质含量≤1μg/g可满足《全精炼石蜡》标准对石蜡嗅味≯1.0号的要求。以限制脱嗅塔底嗅味物质含量为控制点,对除嗅装置塔顶压力、塔进料温度、塔底汽提蒸汽量及塔顶回流量进行优化,可以降低除嗅装置蒸汽消耗,降低整个酮苯联合装置能耗,具有较好的节能效果,可为现有工业装置的操作优化和新建装置的设计提供借鉴。Through simulating the process and calculating the content of odor substances in paraffin of paraffin deodorization unit,combining with literature reports and industrial unit operation results,the content of odor substances that affect the odor of paraffin is determined,which can adapt to the impact of unit operation fluctuation and meet the requirements of the“Fully Refined Paraffin”standard for paraffin odor not exceeding 1μg/g.With limiting the content of odor substances at the bottom of deodorization tower as a control point,the optimization is conducted on top pressure,feed temperature,bottom stripping steam volume,and top reflux flow rate of paraffin deodorization unit,which can reduce steam consumption of paraffin deodorization unit,decline the energy consumption of the entire ketone benzene combination plant,and receive a good energy⁃saving effect.This study can provide references for the operation optimization of existing industrial units and the design of new units.
