TWO:He tried hard to warm her to something more personal. "I might never come back, you know, dear." He realized that he was absolutely begging for affection, most futile and unavailing of all wastes of energy.

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:Six years of fighting, of bloodshed, of heavy loss in blood and treasure to the government, the careers of the incarnate devils Juh, Victorio, and Geronimo—all the evils let loose on the southwest from '78 to '85 were traceable primarily to the selling of bad whiskey to a hunting party of Chiricahuas by two storekeepers, greedy of gain.
  • 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:

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:He walked away, and Geronimo went back to his rancheria on the hilltop, crestfallen. He had failed of his effect, and had not by any means made his own terms.She could not help looking at him now, and his eyes held hers through a silence that seemed to them so enduring, so unreasonable, that Landor must wonder at it. But he had seen men put at a disadvantage by her beauty before, and he had grown too used to her lack of conventionality to think much about it, one way or the other.
