Abstract:		"Volatile organic compound (VOCs) emissions and control technologies of about 609 industrial enterprises in Qinhuangdao City were investigated in this study. The results showed that the exhausted emission flow rates from the industries of oil processing, coking, and nuclear fuel processing were found to be the largest sources of VOCs in Qinhuangdao City (normally above 10(5) m.h(-1)), whereas the other industrial emission flow rates were mainly within the range of 10(3)-10(5) m(3).h(-1). The detected VOC concentrations for all the industries were less than 1000 mg.m(-3). The VOCs emission rates were between 50-10000 g.h(-1), but demonstrated different characteristics among the various industries. It was found that the industries of transportation equipment manufacturing, petroleum processing, coking, nuclear fuel processing, machinery and equipment manufacturing, printing and reproduction of recorded media, and chemical raw material and chemical product manufacturing had much higher concentrations and emission rates than other industries did. However, the overall VOCs emission level from this city was still lower when compared to previous reports for other regions of China. The investigation of the VOCs control technology application showed that there were 109 constructed or operated VOCs treatment facilities among the 609 industrial enterprises. Activated carbon adsorption technology accounted for the largest proportion among the various techniques, with 69%, followed by absorption technology (19%)"
