Abstract
Abstract
Based on the demand for volatile organic compounds (VOCs) emissions controlled in Tianjin, VOC emissions compositions from four typical solvent use industries (automobile painting, furniture painting, wood-based panel manufacturing, Packaging & Printing) were measured by field sampling and analysis, the influence of different treatment facilities on VOCs composition and the ozone formation potentials (OFP) of species were analysed. The results showed that the major VOCs emissions species were aromatics and oxygenated VOCs. Among all waste gas treatment facilities, the catalytic combustion system could reshape the VOCs profile from different industries, and which made the proportion of ethylene increased from 5.81% to 28.30%. Aromatics had a great influence on OFP. The VOCs species with the largest OFP contribution was m/p-xylene, which contributed 16.36% of the total OFP.
