QYD传质内件在变脱塔中的应用

Use of Type QYD Mass-Transfer Internals in Desulfurizing Column for Shifted Gas

由于变脱塔(填料塔)配置偏大,不仅脱硫后H2S含量长期超标、电耗偏高,而且堵塔现象严重。变脱塔改用QYD传质内件后,脱硫后H2S含量完全达标,年节电50万元、减少辅材消耗15万元,并从根本上解决了脱硫塔堵塔问题,取得了满意的效果。

As the size chosen of the desulfurizing column （packed column） for shifted gas is too large, the H2S content after desulfurization exceeds the standard over a long period of time, the power consumption remains high, serious plugging of the column Occurs. With replacement by the QYD mass-transfer internals in the column, the H2S content after desulfurization reaches the standard fuIIy, a saving of 500 000 yuan in power is achieved annually, with a decrease of 150 000 yuan in accessory materials, the plugging of the desulfurizing column is fundamentalIy eliminated, and satisfactory results are obtained.
