The measures and effect of index optimization of tail gas emissions in 60 kt/a WPA plant by dihydrate-hemihydrate process are summarized and analyzed. With the reformation measures including by ensuring at least three grades washing for tail gas, low temperature and fluoride content of washing liquid, enough aeration area in gas channel, timely removal of silica gel in vapor liquid separation components etc., the index of tail gas emissions is optimized.
