石油化工廢氣處理處理工藝簡(jiǎn)述:
洗滌法
◆石油化工廢氣處理的原理:
將氣體通入含噴淋系統(tǒng)的洗滌塔中,氣體經(jīng)過填料床的均勻分布,與洗滌液充分接觸,利用氣體中污染物的溶解性或化學(xué)性質(zhì),將氣體中的污染物吸收或通過化學(xué)反應(yīng)去除,從而達(dá)到氣體凈化的目的。除此之外,洗滌塔還有降溫、除塵、除油的作用。通常采用的方式為逆流式洗滌。常用的洗滌劑包括清水、植物液、硫酸溶液、氫氧化鈉溶液、次氯酸鈉溶液等。其中清水洗滌和植物液洗滌是利用污染物的溶解性,植物液的一些基團(tuán)也參與化學(xué)反應(yīng);硫酸溶液洗滌、氫氧化鈉溶液洗滌和次氯酸鈉洗滌則是利用了污染物的化學(xué)性質(zhì)。
◆石油化工廢氣處理的特點(diǎn):
(1)反應(yīng)快速,洗滌劑與氣體接觸的時(shí)間一般不超過12秒;
(2)適用性強(qiáng),常和其它處理工藝結(jié)合,是有效的預(yù)處理設(shè)施;
(3)常用立式結(jié)構(gòu),節(jié)約占地;
(4)操作簡(jiǎn)單,除了定期更換洗滌劑外基本為無(wú)人操作(洗滌劑更換也可通過增加配套PLC自動(dòng)控制系統(tǒng)實(shí)現(xiàn)無(wú)人操作);
(5)工藝靈活,若氣體性質(zhì)發(fā)生變化,則通過更換洗滌劑即可繼續(xù)使用;
(6)建設(shè)成本低。
◆石油化工廢氣處理的適用條件:
適用性較強(qiáng),可起到除塵、除油、降溫、除臭的作用,常作為其它工藝的預(yù)處理設(shè)施。
◆石油化工廢氣處理應(yīng)用于石化行業(yè):
洗滌法應(yīng)用于石化行業(yè)的具體表現(xiàn)形式為油洗塔。油洗塔是乙烯裝置熱回收區(qū)的關(guān)鍵核心設(shè)備,其作用是將來(lái)自裂解爐的裂解氣中的重油和輕油組分冷凝,并zui大的實(shí)現(xiàn)熱量回收。原理為將來(lái)自裂解爐的裂解氣和急冷油/水逆流接觸冷卻,裂解氣中的重油和輕油組分因此得以冷凝。冷凝的熱媒和冷媒可采用直接或間接接觸形式進(jìn)行熱交換。
石油化工廢氣處理蓄熱焚燒技術(shù)原理: 安居樂VOC沸石轉(zhuǎn)輪濃縮GRTO裝置簡(jiǎn)介: Zeolite Rotary Concentrator Wheel+ GRTO:
How to treat low concentration with large air flow waste stream? Shanghai Anjule has patent designed solutions with the zeolite concentrators to reduce the air flow of the pollutant and concentrate the VOCs before the RTO treatment. Improve the removal efficiency, reduce the operating cost while meeting the regulations. This is a leading technologies in treating VOCs and HAP.
The process flow for zeolite rotary concentrator wheel+ RTO (RCO)
; Anjule technology can be applied to work with the process specifications. For example, emission from coating industrial has the characteristic of high air volume: the waste gas was sent to the G-vortex column to remove particulate. After the dehumidifier process, the waste gas was sent to a specially designed filter before entering the rotary concentrator for VOCs adsorption. The removal efficiency can achieve VOC removal efficiency above 90%. A system fan was installed to release the cleaned air, which is in compliance with the regulations. The air stream then transfer to the RTO for further treatment.
1. Rotary entrance with G-vortex column Anjule G-vortex column has a unique vortex structure, purify and remove the paint organic substance from gas. The advantage: 1. Avoid the blockage of the packing media; reduce the operating cost; and achieve high removal efficiency of VOC substance. Minimize the accumulation of the paint substance0n the rotary and at a result prevent fire hazard.
2. Advance rotary device
Aujule has set up a laboratory and an engineering center for the design of the exhaust gas VOC treatment. The rotary wheels are imported from Japan; the VOC compounds removal rate are measured in a laboratory to ensure the successful treatment for the environmental projects. The advantage of our rotary concentrator: small size, convenience, low pressure lost and work continuously to concentrate low VOC concentration waste gas. The rotary processed gas has a high concentration of VOC with less volume and therefore reduce the amount of the waste gas for the RTO treatment.
3. Safety guarantee Patent designed of Anjule GRTO has put the fire, explosions and other safety factors into fully consideration. The operation of the GRTO is steady, safe and reliable.
4. Advance Technology GRTO control system equipped with software and hardware interlocks, through temperature, pressure responses, the system reacts immediately to the safety control of the system. Effectively,protect the safety of the system . RTO control system uses PLC, installed inside of the control panels; equipped with flame intensity detector, temperature controllers, alarm, reset,0n and off switch, emergency stop, and a recorder; RTO system works seamlessly with the production line without interfering to the existing production.
5. The low operating cost advantage Lower operating cost can be achieved with high VOC concentration in the waste stream. Using a rotary concentrator to reduce the volume of the waste gas is a feasible way in decreasing the cost.
