膜蒸馏处理页岩气田采出水的研究进展

A review of membrane distillation in shale gas produced water treatment

综述了膜蒸馏技术在页岩气采出水领域的研究现状,重点介绍了不同的膜蒸馏形式(直接接触式膜蒸馏、真空膜蒸馏、气隙式膜蒸馏、集成膜蒸馏工艺)处理页岩气采出水的研究进展,以及可适用于页岩气采出水处理的新型超疏/双疏膜的制备方法(静电纺丝法、表面涂覆法、化学改性法)的研究现状。

This paper provides an overview on membrane distillation applied in shale gas produced water treatment.The research progress of different membrane distillation forms(direct contact membrane distillation,vacuum membrane distillation,air-gap membrane distillation,integrated membrane distillation process)for treating shale gas produced water are introduced,also the preparation methods of a novel omniphobic membrane(electrospinning,dip-coating,chemical modification)are discussed since this kind of membrane shows good adaptability to shale gas produced water treatment.
