新型高效立体传质塔板在污水汽提装置上的应用

APPLICATION OF NEW MASS TRANSFER TRAY WITH HIGH EFFICIENCY IN WASTEWATER STRIPPER

独山子炼油化工总厂含硫污水单塔汽提装置原处理量为 35m3/h左右 ,为提高到 68m3/h ,采用了河北工业大学开发的一种新型高效立体传质塔板代替原来使用的浮阀塔板。改造后装置处理量达到改造前的 1.5～ 2倍 ,各项排放指标都能满足工艺要求。但改造后汽提塔的分离精度无明显提高 ,装置在操作、工艺流程上还需改进。介绍了这种新型高效立体传质塔板的结构及操作特点。

The processing capacity of the former single sour wastewater stripping tower in Dushanzi General Works of Petroleum Refining and Petrochemicals is about 35m 3/h.To increase the processing capacity to 68 m 3/h,the new mass transfer tray with high efficiency developed by Hebei Industrial University was adopted to replace the formerly used floating valve tray.The processing capacity is 1.5～2 times that before revamping and various effluent indexes meet requirements of the process.The separation accuracy of the stripper has no evident increase and improvements in operation and process are still needed.Configurations and operating features of the new tray were also introduced.
