吸附法回收化工储运过程溢出气的实践与探索

Practice and Exploration of Recovering Overflow Gas during Chemical Storage and Transportation Process with Adsorption Method

分析了现有单级活性炭变温吸附回收技术使用现状,同时对目前创新发展的多级活性炭变温吸附回收技术进行了可行性分析,结果表明:在化工储运生产过程中,采用多级活性炭吸附、蒸汽脱附、常温冷却水冷凝技术回收化工储运过程溢出气比较彻底、安全。

The using status of single-stage activated carbon temperature swing adsorption recovery lechnnlogy was analyzed. A! the same time, the practicability of the developing multi-stage activated earhon temperature swing adsorption recovery technology, was also analyzed. Resulls showed that the overflow gas eouhl be reovered thoroughly and safely wi!h mulli-stage activated carbon adsarption, steam desorption, and room temperature cooling water condensation technology during chemical storage and transportation process.
