Membrane separation type solvent dehydration system

Great attention is recently being paid to global environmental issues, and it is now conceivable that companies will need to treat used solvents themselves. In consideration of this kind of social issue, we have developed a “membrane separation type solvent dehydration system,” which uses a polyimide membrane with superior dehydration properties developed by Ube Industries, Ltd. in combination with our own distillation and concentration technology that has resulted in solvents being more easily recovered.

THREE:Facing him with a grin was Jeff!"Of course," he laughed tolerantly, "I dare say any wilderness were paradise with him."
  • 1Under the distillation system, even in case of azeotropic solvent compositions, this system which remove water vapor by the polyimide membrane will easily dehydrate.
  • 2In comparison with the distillation system, it significantly saves on use of steam.
  • 3Dehydration can be performed through merely supplying evaporated vapor to the membrane module and maintaining the differential pressure between the permeable side and the impermeable side.
  • 4Solvent purity of 99.9% or more can be achieved by carrying out dehydration with a polyimide membrane only.
  • 5The polyimide membrane has superior heat and solvent resistance. Therefore, the vapor permeation system reduces contamination of the membrane and thus extends its life.
THREE:The second place of the airplane had been fitted with a set of dual controls, rudder bar, throttle and joystick so that Jeff, for two successive hops, let Larry put feet on his rudder bar and lightly hold the stick as Jeff manipulated the controls and explained, by use of the Gossport helmet, why he did this or that.

The aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.

THREE:Jeffs a war ace and knows his stuff, Larry mused, and the engine couldnt have died in a better spot. We are high enough and within gliding distance of that old, abandoned private field.
  • 1 Recovery of the detergent solvent Recovery of the cleaning solvent such as electronic parts industry, precision instrument industry.
  • 2Solvent recovery and the refinement Solvent recovery and the refinement such as chemical industry, an industry of medical supplies, food industry, the fermentation industry.
THREE:211She set about cleaning the little revolver, self-cocking, with the thumb-piece of the hammer filed away, that her husband had given her before they were married. To-night she wanted no dinner. She was given to eating irregularly; a good deal at a time, and again nothing for a long stretch. That, too, was in the blood. So she sent the soldier cook away, and he went over to the deserted barracks.
