When selecting produced water treatment technologies, one should focus on reducing the major contributors to the total environmental impact. These are dispersed oil and semi-soluble hydrocarbons, alkylated phenols, and added chemicals. Experiments with produced water have been performed offshore on the Statoil operated platforms Gullfaks C and Statfjord B. These experiments were designed to find how much of the environmentally relevant compounds were dissolved in the water phase and not associated to the dispersed oil in the produced water. Results show that the distribution between the dispersed oil and the water phase varies highly for the different components groups. For example the concentration of PAHs and the C6-C9 alkylated phenols is strongly correlated to the content of dispersed oil. Therefore, the technologies enhancing the removal of dispersed oil have a higher potential for reducing the environmental impact of the produced water than previously considered.
在选择采出水处理技术时,应着重减少对总体环境影响的主要贡献因素。这些因素包括分散油和半溶性碳氢化合物、烷基化酚类以及添加的化学物质。在挪威国家石油公司运营的古尔法克斯C平台和 Statfjord B平台海上进行了采出水实验。这些实验旨在确定有多少与环境相关的化合物溶解于水相,而非与采出水中的分散油相关联。结果表明,不同组分在分散油和水相之间的分布差异很大。例如,多环芳烃和C6 - C9烷基化酚的浓度与分散油含量密切相关。因此,与之前的认识相比,增强分散油去除效果的技术在降低采出水环境影响方面具有更大潜力。
