TWO:Usually impulsive, generally quick to adopt any new suspicion, he surprised his chums by catching Larry by the coat and dragging him back to the ground as his foot rested on the wing-step bracing.He took up his cap from the table, and went.

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:What happened? Who done this? repeated Jeff.No need to tell her that her courage must not falter at that last moment, which would soon come. He knew it, as he looked straight into those steadfast, loving[Pg 131] eyes. She clung to his hand and stooped and kissed it, too; then she went to the children and took them, quivering and crying, into the other room, and closed the dividing door.
  • 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:Positive-ully, Larry! The finest that ever came out of a ten-cent store!

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

THREE:Coming closer as it dropped lower, the amphibian circled in a tight swing over the fairway several times and finally straightened out, flying toward the wind that came from almost due North on this first cool day after a humid July week, and began to grow smaller to the watchers.PRINCE CHARLES EDWARD STUART (THE "YOUNG PRETENDER"). (After the Portrait by Tocque, 1748.)
  • 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:

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
