| Abstract: | "A database of refined raw materials and end treatment-based VOCs emission factors for typical solvent use sources was developed for the Pearl River Delta. For this, the impact of composition and the content of raw materials, production process, and comprehensive end treatment on the emission of VOCs was analyzed. The solvent use sources included printing, furniture manufacturing, and electronic component and equipment manufacturing. The results showed that the main VOCs in the raw materials used in printing were ethyl acetate, propyl acetate, isopropanol, propanol, and ethanol, which contributed 60%-80% to the total amount of VOCs. Ethyl acetate and butyl acetate were the main oxygenated VOCs (OVOCs) from the raw materials used in furniture manufacturing, contributing 45%-65% of the total. The main VOCs from the raw materials used in electronic component and equipment manufacturing were OVOCs such as alcohols, ethers and phenols, BTEX, and halohydrocarbons. The uncontrolled and controlled emission factors for VOCs from printing were 415.2 kg.t(-1) and 184.3 kg.t(-1), respectively. Of these, solvent-based raw materials accounted for 704.9 kg.t(-1) and 200.1 kg.t(-1), water-based raw materials accounted for 325.6 kg.t(-1) and 230.3 kg.t(-1), UV raw materials accounted for 197.0 kg.t(-1) and 129.0 kg.t(-1), and plant-based raw materials accounted for 89.0 kg.t(-1) and 89.0 kg.t(-1), respectively. The uncontrolled and controlled emission factors for VOCs from furniture manufacturing were 379.0 kg.t(-1) and 290.2 kg.t(-1), respectively. Of these, solvent-based raw materials accounted for 603.0 kg.t(-1) and 448.5 kg.t(-1), water-based raw materials accounted for 80.0 kg.t(-1) and 80.0 kg.t(-1), and powder raw materials accounted for 230.0 kg.t(-1) and 184.0 kg.t(-1), respectively. In electronic component and equipment manufacturing, the uncontrolled and controlled emission factors (unit:kg.million(-1)) for VOCs from AC ceramic capacitors, CC ceramic capacitors, varistors, and aluminum electrolytic capacitors were 59.7 and 40.8, 394.1 and 269.6, 282.4 and 193.2, and 1.2 and 1.0, respectively. The uncontrolled and controlled emission factors for VOCs from the manufacturing of continuous terminals, enameled wire, and printed circuit boards were 56.3 kg.t(-1) and 42.8 kg.t(-1), 87.2 kg.t(-1) and 28.3 kg.t(-1), and 26.4 kg.(100 m(2))(-1) and 11.6 kg.(100 m(2))(-1), respectively" |
