发布时间：2018-07-23 11:24
【摘要】：中国石油吉林石化公司有机合成厂是专业生产丁苯橡胶的企业,后处理单元的废气中主要含有苯乙烯与丁二烯等挥发性有机物,因装置建设年代较早,后处理单元的有机废气一直没有处理设施,而是通过排气管线直接排往大气。石化装置在生产运行过程中会产生大量的挥发性有机废气(VOCs),如果不经处理而直接排放,将会对周围环境造成严重污染并危害人体健康,因此必须对有机废气进行有效的处理和净化后才能排入大气。有机废气的治理技术有冷凝法、吸收法、吸附法以及燃烧法等。蓄热催化燃烧法工艺简单,操作方便,是石油化工、食品、材料等生产中含有机废气的主要处理方法。本文基于以上背景,针对丁苯橡胶装置废气排放特点,选择蓄热式催化燃烧法作为处理丁苯橡胶尾气的工艺路线,通过具体工艺设计,旋转翼型反应器等设备的设计与选择,建成了蓄热催化氧化燃烧系统。利用系统实际运行情况,研究了催化反应温度,操作气速,废气进气量,反应器进出口温度对催化反应的影响,得出了最优的工艺运行参数。经过蓄热催化氧化燃烧系统处理后,最终达到有机废气去除效率95%,非甲烷烃4.0mg/m3,苯乙烯排放量26kg/h,处理后的气体符合《大气污染物综合排放标准》(GB16297-1996),《恶臭污染物排放标准》(GB14554-93)的标准。
[Abstract]:The organic synthesis plant of PetroChina Jilin Petrochemical Company is an enterprise specializing in the production of styrene-butadiene rubber. The exhaust gas of the reprocessing unit mainly contains volatile organic compounds, such as styrene and butadiene, because the plant was built earlier. The organic waste gas of the reprocessing unit has not been treated, but is discharged directly to the atmosphere through the exhaust pipe line. A large amount of volatile organic gas (VOCs) will be produced during the production and operation of petrochemical plant. If it is discharged directly without treatment, it will cause serious pollution to the surrounding environment and endanger human health. Therefore, organic waste gas must be effectively treated and purified before it can be discharged into the atmosphere. Organic waste gas treatment techniques include condensation, absorption, adsorption and combustion. The regenerative catalytic combustion process is simple and easy to operate. It is the main treatment method of organic waste gas in petrochemical, food and material production. Based on the above background, according to the exhaust gas emission characteristics of SBR plant, the regenerative catalytic combustion method is selected as the process route of treating SBR tail gas. Through the specific process design, the design and selection of the rotating airfoil reactor and other equipment, etc. A regenerative catalytic oxidation combustion system was built. The effects of reaction temperature, operating gas velocity, exhaust gas intake and reactor inlet temperature on catalytic reaction were studied, and the optimal operation parameters were obtained. After the treatment of regenerative catalytic oxidation combustion system, the removal efficiency of organic waste gas is 95%, non-methyl alkane 4.0 mg / m 3, styrene emission 26 kg / h, and the treated gas conforms to the standard of Integrated Air Pollutant discharge Standard (GB16297-1996) and odor pollutant discharge Standard (GB14554-93).
