Several operational issues in sulfuric acid production
Thread Content
In two-stage roasting for arsenic removal, what level of residual sulfur in the slag from the first-stage furnace is optimal for arsenic removal? At what temperature is the outlet of the quench tower most favorable for the operation of the bag filters? Please provide an answer. Thank you
If arsenic removal is carried out using a quench tower, the temperature of the material entering the tower is 350°C–370°C, and the temperature after quenching is generally around 150°C.
