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:He naturally did not foresee anything serious, and he only said, "Well?" and began to fill his pipe from a[Pg 83] buckskin pouch, cleverly sketched in inks with Indian scenes. "By the way," he interrupted as she started to speak, "what do you think of this?" He held it out to her. "That fellow Cairness, who wouldn't stay to luncheon that day, did it for me. We camped near his place a couple of days. And he sent you a needle-case, or some such concern. It's in my kit." She looked at the pouch carefully before she gave it back; then she clasped her hands under her head again and gazed up at the manta of the ceiling, which sagged and was stained where the last cloud-burst had leaked through the roof.It is evident that what Plotinus says about beauty and love was suggested by the well-known passages on the same subject in the Phaedrus and the Symposium. His analysis of aesthetic emotion has, however, a much more abstract and metaphysical character than that of his great model. The whole fiction of an antenatal existence is quietly let drop. What the sight of sensible beauty awakens in a philosophic soul is not the memory of an ideal beauty beheld in some other world, but the consciousness of its own idealising activity, the dominion which it exercises over unformed and fluctuating matter. And, in all probability, Plato meant no more than thisin fact he hints as much elsewhere,433but he was not able or did not choose to express himself with such unmistakable clearness.
  • 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:He changed it to a laugh. "A scout married is a scout marred. I am a rancher now. It behooves me to accept myself as such. I have outlived my usefulness in the other field."

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

THREE:Which happened upon the following day. And he was there to see it all, so that the question he had not cared to ask was answered forever beyond the possibility[Pg 198] of a misunderstanding. It was stable time, and she walked down to the corrals with him. He left her for a moment by the gate of the quartermaster's corral while he went over to the picket line. The bright clear air of a mountain afternoon hummed with the swish click-clock, swish click-clock of the curry-combs and brushes, and the busy scraping of the stable brooms in the stalls.
  • 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:The major told him a little reluctantly. "Well, it's this, then: Brewster will not, or cannot, defend your conduct in the matter of the San Tomaso volunteers."Not alone is Sandy on watch, but I arranged to have Tommy Larsen bring his airplane to the golf green Jeff used this afternoon, Mr. Whiteside told them, as he walked, recovering breath, toward the hangar door.

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