【摘要】：中國石油吉林石化公司有機合成廠是專業(yè)生產(chǎn)丁苯橡膠的企業(yè),后處理單元的廢氣中主要含有苯乙烯與丁二烯等揮發(fā)性有機物,因裝置建設(shè)年代較早,后處理單元的有機廢氣一直沒有處理設(shè)施,而是通過排氣管線直接排往大氣。石化裝置在生產(chǎn)運行過程中會產(chǎn)生大量的揮發(fā)性有機廢氣(VOCs),如果不經(jīng)處理而直接排放,將會對周圍環(huán)境造成嚴重污染并危害人體健康,因此必須對有機廢氣進行有效的處理和凈化后才能排入大氣。有機廢氣的治理技術(shù)有冷凝法、吸收法、吸附法以及燃燒法等。蓄熱催化燃燒法工藝簡單,操作方便,是石油化工、食品、材料等生產(chǎn)中含有機廢氣的主要處理方法。本文基于以上背景,針對丁苯橡膠裝置廢氣排放特點,選擇蓄熱式催化燃燒法作為處理丁苯橡膠尾氣的工藝路線,通過具體工藝設(shè)計,旋轉(zhuǎn)翼型反應(yīng)器等設(shè)備的設(shè)計與選擇,建成了蓄熱催化氧化燃燒系統(tǒng)。利用系統(tǒng)實際運行情況,研究了催化反應(yīng)溫度,操作氣速,廢氣進氣量,反應(yīng)器進出口溫度對催化反應(yīng)的影響,得出了最優(yōu)的工藝運行參數(shù)。經(jīng)過蓄熱催化氧化燃燒系統(tǒng)處理后,最終達到有機廢氣去除效率95%,非甲烷烴4.0mg/m3,苯乙烯排放量26kg/h,處理后的氣體符合《大氣污染物綜合排放標準》(GB16297-1996),《惡臭污染物排放標準》(GB14554-93)的標準。
[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).
