OVERVIEW OF INNOVATIVE WAYS TO SOLVE THE ENVIRONMENTAL PROBLEM OF ACID SLUDGE
The article discusses innovative methods for the disposal of waste from the petrochemical industry of the second class of environmental hazard - acid sludge: electrochemical method, thermal thin-layer cracking and a group of modern methods of neutralization (using neutralizing agents - inorganic and organic substances). The advantages and disadvantages of each of the considered methods are revealed. The control waste analysis method showed a decrease in the acid number for each method presented in the review. An increase in the efficiency of dehydration and the receipt of utilization products with improved operational characteristics are noted. Schematic images of modern technologies for acid sludge processing are given.
