The working principle of extraction column in hydrogen peroxide production was introduced. Factors affecting the operation of extraction column were analyzed, including extraction ratio, composition of working solution,acidity of oxidant solution,extraction tower temperature, acidity of extraction water, column top interface, extraction concentration,extraction raffinate, etc. The control range of various process parameters of the extraction tower was determined. As a result, flooding in extraction column was reduced, and the hydrogen peroxide unit can operate safely and stably.
