Abstract

A SYSTEM FOR CARBONIZATION OF GLYCERIN PITCH RANGING FROM GLYCERIN THAT IS ORIGINALLY VISCOUS AND LOW IN LIQUID CONTENT TO GLYCERIN PITCH THAT IS HIGH IN LIQUID CONTENT. THE SYSTEM COMPRISING A CARBONIZATION DRUM (13) WITH AN ATTACHED CARBONIZATION OVEN (21) RECEIVING HEATED GASES FROM A MAIN COMBUSTION CHAMBER (21) FOR THE CARBONIZATION OF GLYCERIN PITCH THAT IS ORIGINALLY VISCOUS AND LOW IN LIQUID CONTENT. THE SYSTEM FURTHER COMPRISES A DRYING DRUM (12) WITH AN ATTACHED DRYING OVEN (23) RECEIVING HEAT FROM A DEODORIZER (15) TO DRY GLYCERIN PITCH THAT IS ORIGINALLY HIGH IN WATER CONTENT BEFORE IT BEING TRANSFERRED TO THE CARBONIZATION DRUM (13) FOR ITS FINAL TREATMENT. A HEAT EXCHANGER (17) IS PROVIDED TO ENABLE RECYCLING PART OF THE HEAT CONTENT FROM THE HOT GASES ORIGINATED FROM THE MAIN COMBUSTION CHAMBER (21) FOR DRYING THE GLYCERIN PITCH IN THE DRYING DRUM (12). GLYCERIN PITCH IS REDUCED, AFTER CARBONIZATION IN THE CARBONIZATION DRUM (13), TO DRY RESIDUES WHICH ARE SAFE TO BE DISPOSED IN THE NORMAL MANNER AND THE GASES FROM THE DRYING PROCESS AND THE CARBONIZATION PROCESS EFFECTIVELY CLEANSED BEFORE THEIR EMISSION TO THE ATMOSPHERE. A PROCESS IS PRESENTED FOR TREATING GLYCERIN PITCH WITH THE ABOVE MENTIONED SYSTEM WHEREIN SAID GLYCERIN PITCH IS REDUCED TO DRY RESIDUES THAT CAN BE DISPOSED SAFELY AND WITH THE GASES PRODUCED IN THE PROCESS ADEQUATELY CLEANSED TO BE DISCHARGED TO THE ATMOSPHERE. GLYCERIN PITCH CAN BE TREATED BY THE SYSTEM BASED ON CONTINUOUS OR BATCH FEEDING DEPENDING ON THE WASTE CONTENT AND TREATMENT CAPACITY.
