Abstract: The current situation of formaldehyde dealcoholization tower is summarized.Problem of frequent plugging in the dealcoholization system is solved through optimizing the production process,reducing the feed rate to the dealcoholization tower,re-designing the vacuum equalization line in the dealcoholization tower and assembling dual filters for the reflux pump of the dealcoholization tower.And the system clean-up time is also reduced,the efficiency of the dealcoholization column is improved,the methanol content in refined formaldehyde drops from 1.8% to 1% and stable production is achieved.
