TWO:Then stand to your glasses steady,It was plain, even to Felipa, how thoroughly he enjoyed being with one who could talk of the past and of the present, from his own point of view. His Coventry had been almost complete since the day that the entire army, impersonated in Crook, had turned disapproving eyes upon him once, and had then looked away from him for good and all. It had been too bitter[Pg 310] a humiliation for him ever to subject himself to the chance of it again.

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 told her, and she held it out to him. He started to take it, then pushed it away.
  • 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:It was not a nice outlook. But he found it did not grow any better for the thought that Felipa might have forgotten all about him, though that would unquestionably have been the best thing that could have happened for all concerned, from the standpoint of common sense. But there were two chances, of a sort, that made it worth while worrying along. One was that Felipa might some day, in the working out of things, come into his life. The other was that he could ferret out the truth of the Kirby massacre. Love and revenge are mighty stimulants.

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

THREE:And now it was a struggle of sheer force and agility. She managed to whip out the knife from her belt and to strike time and time again through sinewy flesh, to the bone. The only noise was the dragging of their feet on the sand, the cracking of the willows and the swishing of the blade. It was savage against savage, two vicious, fearless beasts.
  • 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.

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