Because elemental phosphorus is prone to spontaneous combustion and severely corrodes steel after combustion, the tail gas of yellow phosphorus cannot be recovered at all. The traditional process uses high-altitude combustion and is directly emptied, resulting in a lot of waste of resources and serious environmental pollution.

 

The company uses special processes and the company’s proprietary special adsorbents to purify yellow phosphorus tail gas to produce high value-added products such as sodium formate, formic acid, oxalic acid and methanol. After purification, the hydrogen sulfide content in the yellow phosphorus tail gas is <10mg/m3, and the total phosphorus content <10 mg/m3, arsenic content <0.5 mg/m3, hydrogen fluoride content <5 mg/m3, meeting the requirements for raw gas for the production of one-carbon chemical products.
