摘要
本论文的主要任务是以催化氧化技术(CO)为核心对某苯酚丙酮装置氧化工序的氧化尾气进行处理,采用国产催化剂(钯催化剂)替代进口催化剂,将尾气中的有机物转化为二氧化碳和水,并放出能量,改造后排气筒中的挥发性有机物排放浓度(以非甲烷总烃为指标考核)为6mg/m3,有机气态污染物苯的排放浓度为2mg/m3,满足北京地标(DB11/447-2015)的排放要求,改善大气环境质量。同时通过优化工艺方案,达到节能降耗的目的。
The main task of this paper is to take catalytic oxidation technology (CO) as the core of the oxidation process of a phenol acetone plant oxidation tail gas treatment,use domestic catalyst (palladium catalyst) to replace the imported catalyst,the organic matter in the tail gas into carbon dioxide and water,and release energy.The emission concentration of volatile organic compounds (assessed by non-methane total hydrocarbon) in the rear cylinder of the reconstruction is 6 mg/m3,and the emission concentration of organic gaseous pollutant benzene is 2 mg/m3,which meets the emission requirements of Beijing Landmark (DB11/447-2015) and improves the quality of atmospheric environment.At the same time,by optimizing the process scheme,to achieve the purpose of energy saving and consumption reduction.
