TWO:"Come, don't waste any time asking questions," answered the nervous little Surgeon. "There's more troops coming right along, and we mustn't take any chances of their catching it."

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:
  • 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:And if you were going to use Alberts at all, Albin thought, you sure as hell had to train them. God alone knew what harm they could do, left alone in a wilderness of delicate machinery without any instructions."And I promise you," said Shorty solemnly, "that you shall have all the chance you want sooner'n you think for. I know a great deal more'n I dare tell you now, but things is workin' to a head mighty fast, and you'll hear something drop before the next change o' the moon. You kin jest bet your shirt on that."

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

THREE:"I'm glad." He was no more than polite. There was no more in him, no emotion at all. He had reached a blank wall: there was no escape for him or for the Alberts. He could see nothing but pain ahead."Well, I'll bet a hatful o' red apples," said Si, "that them was guerrillas that we saw, and they're makin' for this train. The rebels in Nashville somehow got information to 'em about it."
  • 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:"By rights, I ought to be a Jigadier-Brindle," retorted Shorty, "but I never could git Abe Lincoln to take that view of it. Here, fill up your cartridgebox. You'll need lots of 'em, if you're only goin' to shoot to crease your rebels, as that feller did you."

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