Abstract: A set of techniques integrated sampling and analysis was developed to monitor and identify offensive odour emissions from refinery, such as emissions from various storage tanks, wastewater treatment facilities and oxidative sweetening units. The monitoring items nearly covered all the typical refining odorous pollutants and hydrocarbons. Waste gases from odour emission sources were sampled and collected by aspirator bulbs and PTFE bags. Odorous compounds and hydrocarbons in waste gases were identified and semi-quantitatively analyzed by gas chromatography-mass spectrometry. Volatile sulfur compounds in waste gases were analyzed using a wide-bore capillary gas chromatography with sulfur chemiluminescence detection. The contents of total hydrocarbons and C1~C3 hydrocarbons in waste gases were determined by total hydrocarbon analyzer and flame ionization detection-packed column gas chromatography, respectively. The contents of benzene homologues and ammonia were determined according to the relative national standard methods. Some typical odour emission sources were sampled and analyzed from refineries of SINOPEC and the characteristics of odour emissions derived from petroleum refining were investigated systematically and comprehensively.
