TWO:They spurred forward unwillingly, thus urged. At sundown they came to the old lake bed and camped there. According to the citizens it was a regular Indian camping-place for the hostiles, since the days of Cochise.

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:Then he went off to inspect the stock and the pickets, and to double the sentries. "You had better sleep on your arms," he told the soldiers, and returned to his cot to lie down upon it, dressed, but feigning sleep,[Pg 98] that Felipa might not be uneasy. He need not have resorted to deception. Felipa had not so much as pretended to close her eyes that night.
  • 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:"I say, old man, shut that door! Look at the flies. Now go on," he added, as the door banged; and he rose to draw a chair to the table.

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

THREE:The Everdail Emeralds! Larry repeated the phrase sharply. Why, Jeff! Ive read a newspaper story about them, in a Sunday supplement. Thats the matched set of thirty emeralds
  • 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:As a week went by Dick saw something to laugh about in their wild theories, their almost fantastic deductions. He found an old stenographers note book and jotted down, in ludicrous terms, the many clues and suspicious incidents they had encountered."Yes," he persisted, refusing to be thwarted, "once when you were crossing the parade at Grant, at retreat, and two days afterward when you shot a blue jay down by the creek."

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