摘要
以红山嘴油田红浅1井区火驱先导试验烟道气处理为例,火驱烟道气中非甲烷总烃(NMHC)含量及H_2S浓度无法满足GB 16297—1996《大气污染物综合排放标准》、GB 14554—1993《恶臭污染物排放标准》,必须对此进行处理。文章对比分析了常用处理工艺技术特点,提出蓄热式氧化工艺处理烟道气具有对NMHC、H_2S、CO等摧毁效率高;对火驱低热值含硫采出气处理负荷调节范围大,处理后烟气满足环保排放标准等技术优势;经过矿场试验,验证了热氧化工艺处理含H2S低浓度烷烃气体的可行性,处理后的气体满足上述标准排放要求,为后续火驱开发提供了技术支持,具有一定的应用价值。
For the non-methane hydrocarbon content and H2 S concentration of the fireflood flue gas in Hongqian 1 well operation area of Hongshanzui Oilfield cannot meet the requirements in the standard of 'Integrated Emission Standard of Air Pollutants '(GB16297—1996)and 'Emission Standards for Odor Pollutants'(GB14554—1993),treatment measurement should be taken.In this paper,the technical characteristics of common treatment technologies are compared and the technical advantages of regenerative thermal oxidation(RTO)to flue gas treatment are put forward.Through field test,the feasibility of RTO to treat hydrogen sulfide and low concentration alkane gas is verified.The treat flus gas can meet the requirements of former standards and this technology provides technical support for followed development.
