TWO:"Glory, we're goin' home!" shouted the Deacon, waving his paper exultingly to the railroad men who had been so helpful. But he exulted prematurely. The engine rattled ahead sharply for a few hundred yards, and then began backing to opposite the spot where it had started from.

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:REMOVED FROM THE BATTLEFIELD TO THE HOSPITAL AT CHATTANOOGA.
  • 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:"Hello, awful glad to see you backand you, too, Shorty," said the busy Orderly-Sergeant, speaking in his usual short, snappy sentences, without using any more words than absolutely necessary. "We need you. Short of non-commish. Two Sergeants off on detached duty and two Corporals in hospital. Being worked for all we're worth. Both of you look fine. Had a nice, long rest. In great shape for work. Pitch in, now, and help me. First, let's get the names of these kids on the roll. Humphreyswe've got two other Humphreys, so you'll answer to Humphreys, 3d.

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

THREE:Air conditioning had done something to minimize the reek inside, but not much. Albin devoted most of his attention to keeping his face a complete mask. The last thing he wanted was to retchnot in front of the Alberts, who didn't really exist for him, but in front of Derban. And the party (which he wasn't going to think about) hadn't left his stomach in perfect shape.
  • 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:"If they do," chimed in Si, "they kin pick up plenty more just as good around somewhere, when daylight comes. That's what pioneers is for.""Klegg, Josiah Klegg," answered the Deacon promptly.

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