【摘要】：本文主要通过对国内外码头油气回收治理技术进行搜集资料,了解并分析了目前国内外挥发性有机物回收方法主要有冷凝法、吸收法、吸附法、膜分离法以及其组合工艺方法。近年来我国的原油码头油气回收设备设施已经在逐步增加,设备类型也在不断创新,大多数码头油库储运公司也都以国内自主研发为主。国内码头油气回收处理设备以活性炭吸附法为主,对船舱油气进行油气回收处理,但是已然投入正常生产工作的却是没有先例。通过以兴中公司原油码头油气回收项目为案例进行了较为具体地分析,进一步了解了原油码头油气回收系统。除了四种经典的油气回收方法以外,针对码头油气的治理,原油码头大部分油气中均含有硫成分,故本课题还研究了码头含硫油气的脱硫方法。其中本课题重点主要研究了一种原油码头油气催化燃烧处理的方法。介绍了催化燃烧法国内外的发展现状。到目前为止,国内催化燃烧技术主要集中在两个方面:一是催化剂及制备工艺;二是催化燃烧器及催化燃烧控制技术。对催化剂特性进行了详细的研究,催化剂的载体以及催化剂的使用寿命直接与催化燃烧法整个成本相关。本课题主要自主研究设计了一种催化燃烧法处理油气的系统设备,并设计实验对该设备可行性进行测试,最终得出结论,该设备处理油气效果达到国家标准要求。同时,结果表明码头催化燃烧法适用于石油化工、制药、印刷等行业排放的挥发性有机物VOCs的处理,催化燃烧净化率极高,燃烧温度低,无NO的生成,不会造成二次污染。因此,催化燃烧法也是实用于码头的油气处理,催化剂能够降低燃烧反应活化能,使VOCs在较低温度条件下发生完全氧化反应,并放出大量的热量就能维持催化反应,节省能源。
[Abstract]:In this paper, through collecting data on oil and gas recovery and treatment technology of wharf at home and abroad, we understand and analyze the main recovery methods of volatile organic compounds at home and abroad are condensation, absorption and adsorption. Membrane separation method and its combination process. In recent years, the facilities of oil and gas recovery equipment of crude oil terminal in China have been gradually increased, and the types of equipment have been innovating. Most of the wharf oil storage and transportation companies also rely on domestic independent research and development. Domestic wharf oil and gas recovery and treatment equipment mainly uses activated carbon adsorption method to recover oil and gas from the cabin of the ship. But what has already been put into normal production has no precedent. By taking the oil and gas recovery project of Xingzhong Company's crude oil terminal as a case study, The oil and gas recovery system of the crude oil terminal is further understood. In addition to the four classical methods of oil and gas recovery, most of the oil and gas of the crude terminal contain sulfur in the management of the oil and gas of the terminal. Therefore, the desulfurization method of sulfur containing oil and gas in wharf is also studied in this paper, among which a method of catalytic combustion of oil and gas in crude oil terminal is mainly studied, and the development status of catalytic combustion method at home and abroad is introduced. Domestic catalytic combustion technology mainly focuses on two aspects: first, catalyst and preparation technology; second, catalytic burner and catalytic combustion control technology. The carrier of catalyst and the service life of catalyst are directly related to the whole cost of catalytic combustion method. Finally, it is concluded that the oil and gas treatment efficiency of the equipment meets the requirements of the national standard. At the same time, the results show that the terminal catalytic combustion method is suitable for the treatment of volatile organic compounds (VOCs) emitted from petrochemical, pharmaceutical and printing industries. The catalytic combustion method is also suitable for oil and gas treatment of wharf because of its high purification rate, low combustion temperature and no formation, so the catalytic combustion method can reduce the activation energy of combustion reaction. When VOCs is completely oxidized at low temperature and a large amount of heat is released, the catalytic reaction can be maintained and energy can be saved.
