    摘要： A gas-liquid contact tray with fixed valves for mass transfer, in which the fixed valve comprising an upstream portion, a midportion and a downstream portion is made by punch from the tray deck so as to form as a deflector, and the upstream portion and the downstream portion are integrated with the tray deck, characterized in that said midportion has a central plane portion and downward inclined margins, and the tray deck is further provided with perforations which are arranged between the fixed valves adjacent in the liquid flow direction. The gas-liquid contact tray with fixed valves for mass transfer according to the present invention has a low liquid entrainment, low liquid weeping, a high mass transfer capacity and good turn-down characteristics.

    摘要： A treatment system includes a feed source, a first treatment unit for separating a feed into a first product and a concentrated feed containing less than about 7% total dissolved solids, and a membrane distillation unit for separating the concentrated feed into a second product and a superconcentrated feed containing at least about 14% total dissolved solids. The membrane distillation unit includes hollow fiber membranes having inner bores for receiving the concentrated feed and membrane walls for allowing vapor transmission of distillate. A method includes delivering feed to a first treatment unit where it is separated into first product and concentrated feed streams; delivering the concentrated feed to internal bores of hollow fiber membranes where it is separated into second product and superconcentrated feed streams as vapor passes across the hollow fiber membranes; delivering the superconcentrated feed to a liquid removal unit; and collecting the first and second product streams.
