TWO:"You do me proud," said Shorty with a grin, but an inward feeling that trouble was impending.

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, you rascal, would you assault an officer?" said the newcomer, spurring his horse through the crowd to get at Shorty.The train had started in the meanwhile, but presently the conductor came back into the caboose. He had been a soldier, but so severely wounded as to necessitate his discharge as incapable of further field service.
  • 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:"Our batteries are improvin' wonderfully," commented the more practical Si, studying the field. "They seem to've socked every shell in just where it'd do the most good. No shootin' at the State o' Georgy generally and trustin' to luck to hit a rebel. Every shell seems to've landed just where it was needed, and then 'tended to its business and busted. You don't see no signs of any strikin' a quarter of a mile away, nor a whole one layin' around anywhere. That's good gunnin', and I'm glad our old six-hoss thrashin'-machine done the biggest share of it. Our brigade has the best battery in the whole army.""I think you'll pull through all right," continued the Surgeon, "if you don't have concussion of the brain. You'll have to be"

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

THREE:But the masters say what we have is freedom. I say it is not so. The masters tell us what to do: they tell us to do arithmetic, to do all other school things, and we do not do for ourselves what we want. We do not do anything for ourselves, but always the masters tell us.
  • 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.
