The Effect of Chromic Mud Graining on the Technological Parameters of the Sodium Chromate Production Process
ثبت نشده
چکیده
The most important solution in the new sodium chromate production process implemented in Alwernia Chemical Works is in-process recycling of chromic mud. This allows lessening the hazard to the natural environment resulting from released chromic waste. It also involves economical advantages. This paper presents studies on the optimisation of this process using of a fuzzy logic method. The influence of the grain size of chromic mud on the sodium chromate production process with chromic mud in process recycling has been estimated. The optimal values of the process parameters can be achieved applying preliminary ground chromic mud and fine-ground fractions of chromic ore. “Deep” milling of chromic mud is not necessary.
