Název v původním jazyce

Use of the MSO technology for the tetrachlorethylene disposal

Popis výsledku v původním jazyce

Currently the use of organic chlorinated substances is constantly increasing and their disposal by conventional methods requires a demanding flue gas cleaning system. Molten Salt Oxidation (MSO) technology is a technology that uses flameless oxidation below the surface of the molten salt. The acidic off-gases are trapped in the molten alkali carbonates with which they react to form respective compounds and thus this system does not require a complex flue gas cleaning. Five experiments were performed on two reactor MSO laboratory apparatus. Pure Na2CO3 was used as the alkaline salt in both reactors. The set temperature on both furnaces was 1050 °C. The experiments differed in the amount of C2Cl4 dosed and the organic waste dosing rate. The oxidizing air flow was 4.5 l·min-1 and was fed to the first reactor. During the experiments, the temperature profile in each reactor was measured, flue gas analysis was performed and at the end of the experiment, samples of the molten salt were taken to determine the content of chlorides. Chlorides were determined by argentometric titration. The efficiency of C2Cl4 oxidation was monitored by determining the CO content in the off gases. The whole process was optimized during the experiments and thus the efficiency improved. The formed Cl2 was captured primarily in the first reactor, where the capture efficiency was around 70%.
