在TeapotDome油田 ,ETVenture公司的 1号ET和粒状活性炭充分混合 ,对Tensleep油层的产出水进行 2 4小时脱烃实验 ,得出如下检测结果 :①产物中全部石油烃 (用工程实践修正的 41 8 1法检测 )的含量可降至非可检测标准 ;②油、脂 (用EPA的 41 3 2 2法检测 )的含量可降至非可检测标准 ;③苯、乙基苯、甲苯和二甲苯 (四类苯化合物用EPA的80 2 0法检测 )可溶性烃类化合物的含量可降至仅为可检测标准。 1号ET和粒状活性炭混合后 ,四类苯含量在可检测限度以下。
At TeapotDome Field, ETVenture’s ET No. 1 and granular activated carbon were thoroughly mixed to conduct a 24-hour dewaxing experiment on the produced water from the Tensleep reservoir. The following test results were obtained: (1) All petroleum hydrocarbons in the product (corrected by engineering practice) 8 1 test) can be reduced to a non-detectable standard; ② the content of oil and fat (detected by the EPA’s method of 41 3 2 2) can be reduced to a non-detectable standard; ③ benzene, ethylbenzene, toluene and bis Toluene (four benzene compounds tested by the 8020 method of EPA) Soluble hydrocarbon content can be reduced to only detectable standards. After the combination of ET No. 1 and granular activated carbon, the content of four kinds of benzene is below the detectable limit.
