摘要： We provide an evaporation based zero-liquid discharge method for generation of steam for enhanced oil recovery (EOR) processes utilizing once-through steam generators (OTSGs). The method includes feeding the OTSG(s) with produced water, vaporizing a fraction of this water for steam injection and blowing down the balance of the water. This water, referred to as OTSG blowdown, can be flashed to produce a vapor stream and a liquid that is fed to a mechanical vapor compression (MVC) evaporative process. The latent energy contained in the vapor stream generated by the upstream flash is beneficially recycled to substantially reduce or eliminate the energy consumption of the MVC process. The evaporative process can be used to reduce the liquid waste for disposal or eliminate the need for liquid disposal by achieving zero liquid discharge.
摘要翻译： 我们提供一种蒸发式零液体排放方法，用于产生用于使用直通蒸汽发生器（OTSG）的增强采油（EOR）方法的蒸汽。 该方法包括将OTSG与生成的水一起进料，汽提一部分该水以进行蒸汽喷射并吹除水的平衡。 称为OTSG排污的这种水可以被闪蒸以产生蒸气流和被供给到机械蒸气压缩（MVC）蒸发过程的液体。 由上游闪蒸产生的蒸汽流中包含的潜能被有利地循环，以显着降低或消除MVC过程的能量消耗。 蒸发过程可用于减少废液排放或通过实现零液体排放来消除液体处理的需要。

摘要： We provide a system and method for reverse osmosis treatment of water, including seawater and brackish water. Methods and systems of embodiments of the invention may include, for example, ultrafiltration followed by biofoulant removal, both of which precede reverse osmosis. In preferred embodiments the system is run at a low flux. For example, a flux of 6-8 GFD may be used with seawater.Additional embodiments may provide the above process in conjunction with a reverse-osmosis membrane cleaning system. The membrane cleaning system is a “clean in place” system that includes use of the natural pressure differential in the reverse osmosis system to remove biofoulants and their precursors.

摘要： A process for the recovery of purified water from a reverse osmosis reject stream includes preconditioning a reject stream to remove scaling ions and provide preconditioned water; separating any precipitate that forms in the preconditioned water to form a feed stream; subjecting the feed stream to high pressure membrane filtration system including a recirculating, high pressure pump generating a permeate stream and a second reject stream; adding a make-up water stream to the feed stream; and separating the permeate stream as purified water. Additional features and embodiments are also provided.
