TWO:The round-up lasted several days longer, and then the men were paid off, and went their way. The way[Pg 167] of most was toward Tombstone, because the opportunities for a spree were particularly fine there. Not because of these, but because the little parson lived there now, Cairness went also. Moreover, it was as good a place as another to learn more about the massacre. Cow-boys coming from other round-ups and getting drunk might talk.

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:"It's not so much that," he evaded, getting up to put a lump of sugar he did not need into his tea, "it's not so much that as it is the everlasting strain of fighting the hands. It would be easier to meet an open rebellion than it is to battle against their sullen ugliness.""That man is going to stay to luncheon," he told her.
  • 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:She kept her sullen glance on the ground, but she was shaking violently.Official business called Brewster to the Agency next day. He stopped overnight, on the way, at a ranch whose owners depended more upon passing travellers than upon the bad soil and the thin cattle. And here fate threw in his way one whom he would have gone well out of that way to find.

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

THREE:
  • 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:

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