Abstract:

With the increasingly stringent requirements of environmental protection, the emission of tail gas from wet-process phosphoric acid production unit has been unable to meet the target requirements. In view of the problems existing in the tail gas washing system of wet-process phosphoric acid unit, the corresponding equipment modification measures are adopted and the process control indexes are optimized. After the modification, not only has the exhaust gas meet the requirments of the national standard, but also the annual economic benefit increases by 1.8 million yuan.
