- 摘要:
- 为解决某成品油库汽车装车系统高浓度油气排放污染、能源浪费及安全隐患问题,结合油库汽车装车挥发性有机物排放规模大、浓度高、场地有限等特点,对吸附法、吸收法、冷凝法、膜分离法及直接燃烧法等主流油气回收技术进行适用性分析,筛选出低温吸收+吸附法的组合工艺路线。通过系统研究吸收油流量、吸收温度等关键参数对处理效果的影响,优化工艺操作条件,并对比常温吸收+吸附与低温吸收+吸附两种方案的技术经济性。结果表明,该油库应采用先吸收后吸附的工艺顺序,优选92#汽油作为吸收剂;低温法和常温法固定资产投资差别不大,虽然低温吸收+吸附法运行费用较高,但由于油库所在地夏季温度偏高,若采用常温吸收法,影响吸附效果,因此推荐采用低温吸收+吸附法的组合工艺路线。研究结果可为同类型高浓度油气回收项目的工艺选型与参数优化提供参考。
To address pollution caused by high-concentration oil vapor emissions during vehicle loading at a refined oil depot, along with energy waste and safety hazards, this paper analyzed the applicability of mainstream oil vapor recovery technologies—including adsorption, absorption, condensation, membrane separation, and direct combustion—considering the depot's characteristics: large-scale volatile organic compound emissions, high concentration levels, and limited site space. A combined process of low-temperature absorption and adsorption was selected. Through systematic investigation of key parameters such as oil flow rate and absorption temperature, operational conditions were optimized, and the techno-economic performance of ambient-temperature versus low-temperature absorption combined with adsorption was compared. The results indicate that the depot should adopt an “absorption followed by adsorption” process sequence, with 92-octane gasoline as the preferred absorbent. Although fixed capital investment is similar for both low-temperature and ambient-temperature methods, the low-temperature absorption+adsorption process, despite higher operating costs, is recommended due to the depot's high summer temperatures that would otherwise impair adsorption efficiency in ambient-temperature absorption processes. The study provides useful references for process selection and parameter optimization in similar high-concentration oil vapor recovery projects.
