摘要
建立了炼油厂各类贮罐呼吸气、污水处理场逸散气及氧化脱硫醇尾气等恶臭无组织排放源的采样与分析成套技术,监测项目基本涵盖石油炼制特征恶臭污染物和油气组分。废气样品用双连球和聚四氟乙烯采样袋采集。废气中特征恶臭污染物的组成及烃类碳数分布用气相色谱/质潜法定性和半定量分析,挥发性硫化物含量用新型的硫化学发光检测/宽口径毛细管气相色谱法分析,总烃含量用总烃分析仪法分析,C_1～C_3烃类含量用火焰离子化检测/气相色谱法分析,苯系物和氨气含量参照国家标准方法分析。监测了多家烁油厂的典型恶臭污染源,较为全面和系统地获取了炼油厂恶臭污染源排放特征。
A set of techniques integrated sampling and analysis was developed to monitor and identi- fy 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 typicalrefining 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 sul- fur chemiluminescence detection. The contents of total hydrocarbons and C1--Ca 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 ac- cording to the Chinese national standard methods. Some typical odour emission sources were sampled and analyzed from refineries of SINOPEC and the characteristics of odour emissions derived from petro- leum refining were investigated systematically and comprehensively.
