Life Cycle Assessment of Oilfield Produced Water Treatment Technology

The pollution caused by the construction, operation and scrap of the oilfield produced water treatment technology has gained growing attention. This article focuses on the quantitative study of the oilfield produced water treatment, and takes a sewage treatment plant as the example to study the environmental impact load of the whole life cycle with the life cycle assessment method and Gabi software. The result of the research shows that the most significant impact is marine aquatic ecotixicity potential, followed by human toxic potential, global warming potential, acidification potential, and photochemical ozone creation potential. Lastly, this article proposes improvement measures according to results of evaluation to reduce resource consumption and pollutant emissions.
