Abstract:A survey was developed to collect information on full-scale industrial gaseous VOCs treatment facilities. Based on 771 VOCs treatment cases, the application status of different VOCs treatment techniques was analyzed. By investigating the marketing occupation ratio, gas flow rate, VOCs concentration, VOCs type and the industry type. Catalytic oxidation, adsorption and biological removal was found to be the most popular types of technique, but other techniques and combination of different techniques were still important. Generally speaking, condensation, membrane separation and adsorption were found to be fit to treat and recover VOCs gases with concentrations higher than 10000 mg/m3. Thermal oxidation and catalytic oxidation were much fitter to treat VOCs gases with concentrations from 2000mg/m3 to 10000mg/m3. Biotechnique and plasma oxidation were fit to treat VOCs gases with concentration lower than 2000 mg/m3. Besides the VOCs concentrations, some other characteristics of the VOCs gas, performance and economics of the techniques as well as the emission standard should also be considered before a proper technique is selected.
