Abstract: Systems and processes for purifying and concentrating a liquid feed stream are disclosed. In the systems, the concentrated liquid output from the high pressure side of a reverse osmosis stage is used as the draw solution in the low pressure side of the reverse osmosis stage in a configuration called osmotically assisted reverse osmosis. This reduces the osmotic pressure differential across the membrane, permitting high solute concentrations to be obtained, hastening the purification of the liquid. Reduced system pressures are also obtained by arranging multiple osmotically assisted reverse osmosis stages in a cross-current arrangement. Overall system energy consumption is reduced compared to conventional thermal processes for high concentration streams.

Abstract: Systems and methods for separating components from a fluid stream are described. The systems and methods described herein may be specifically well suited for separating solids, hydrocarbons, chemicals, non-evaporable components, etc., from wastewater produced by oil and gas recovery. The systems and methods may generally include the use of a heat exchanger through which a fluid stream is passed to thereby evaporate some or all of the fluid stream. The heated stream exiting the heat exchanger may include vapor, liquids and/or solids. This heated stream is then subjected to phase separation to separate a vapor stream from a liquid/solids stream. The vapor stream is then transported back to the heat exchanger where it is used to transfer heat from the vapor stream to the fluid stream. During the operation of the heat exchanger, a scraping system may be used to scrape the one or more surfaces of the passage through which the fluid stream flows in order to prevent buildup of solids and liquids thereon.

Abstract: The present application pertains to systems and methods for desalination. In one embodiment the system employs a first storage reservoir configured to be near the surface of a body of water and configured to store a low density fluid. A second storage reservoir is configured to be located below the surface of the body of water. A desalination system is operably connected to the second reservoir. Desalinated water is produced by allowing desalination permeate to displace low density fluid in the second reservoir and transfer the low density fluid from the second reservoir to the first reservoir. Desalinated water is exported by transferring low density fluid from the first reservoir into the second reservoir to displace desalinated water from the second reservoir into a water export pipeline.

Abstract: A water treatment system of coupling a heat pump with multi-effect evaporation that comprises a lithium bromide absorption-type heat pump circulation system, a multi-effect evaporation circulation system and a compression-type heat pump circulation system is provided. The vapor in a tail-end evaporator of the multi-effect evaporation circulation system is introduced into a generator in the absorption-type heat pump to release heat and condense. A dilute solution in an absorber of the absorption-type heat pump is introduced into a first-effect evaporator to be evaporated by a treated water, and a condensation heat of the vapor generated by the generator of the absorption-type heat pump is recovered by an evaporator of a compressor heat pump, and another air source evaporator absorbs heat from ambient air to supply heat for the generator by a heat pump condenser.
