PROCESS FOR REDUCING THE POLLUTION OF OPERATING FLUIDS OF VACUUM PUMPS WHEN PURIFYING EXHAUST GASES FROM VACUUM PYROLYSIS INSTALLATIONS AND/OR EXTRUSION PROCESSES

摘要

process for the purification of exhaust gas generated by the pyrolysis plants under vacuum by suction and exhaust combustion gas, air supply. the exhaust gases are subjected, immediately after training, full combustion, while the gaseous reaction products.the process is controlled by air supply and the presence of depression from 0.5 to 0.95 bar (500 to 50 mbar (absolute) generated by a vacuum pump. the gaseous reaction products are then cooled to a temperature of between 10 and 25 degrees, so that the vacuum pump (6) is damaged.the reaction products were then cooled gas sucked by the vacuum pump.
