稀硫酸吸收法处理含三乙胺尾气工艺

The triethylamine tail gas treatment process using diluted sulphuric acid absorption method

介绍了利用稀硫酸吸收法处理含三乙胺尾气的工艺原理,并利用自主研发的技术建设了国内首套尾气处理装置。详细分析了该装置的工艺流程、设备选型、运行参数及存在的问题、优化措施等。装置投入运行后有效地解决了尾气中三乙胺超标排放问题,经环保部门多次检测,尾气均达标排放。

The triethylamine tail gas treatment process using diluted sulphuric acid absorption method was discussed. The first tail gas treatment unit using this technology was set up. The process steps, equipment selection, operation parameters and existing prob- lems, and optimization measures were analyzed in details. After the unit was put into operation, the problem of excessive triethyleamine emission in the tail gas was solved. The tail gas was monitored by the Environmental Protection Department many times and the results showed that the concentration of triethlyamine in tail gas met the emission standard.
