Air Emission Management
VOCs – Volatile Organic Compounds 揮發(fā)性有機化合物
It is a class of prevalent and complex organic pollutants, including paraffin, olefins and aromatics and other substances.
VOCs是空氣中普遍存在且組成復雜的一類有機污染物的統(tǒng)稱，主要包括烷烴、烯烴和芳香烴等物質(zhì)
VOCs will turn into secondary organic aerosol particle by going through complicated photochemical reaction, and become an significant source of PM2.5.
通常情況下這些揮發(fā)性氣體直接排放到大氣中后會直接形成大氣污染源。此外，VOCs還可以經(jīng)過復雜的光化學反應(yīng)，生成顆粒物二次有機氣溶膠，成為PM2.5的重要來源之一。
Emissions to air are commonly generated from:
Core facility operations 生產(chǎn)過程
Non - Core facility operations 非生產(chǎn)過程
