Abstract: The tail gas of yellow phosphorus，which contains high concentrated carbon monoxide，is an important resource.After purification，it can be used as the raw material in chemical production to produce high value-added products，such as oxalic acid，formic acid and methanol etc.This article summarized the yellow phosphorus tail gas purification treatment technology and comprehensive utilization experiences，and put forward the technical measures for reduction of impurities，such as phosphorus and sulfur etc.in yellow phosphorus tail gas.In view of the existing problems，and according to the scientific development concept，this article proposed several recommendations for green production based on the concept of recycle economy.
