TWO:"Why are you so all-fired anxious to vindicate the law?" He dropped easily into phrases.

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:"I do," she answered, blinking lazily.

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

THREE:The fight began with a shot fired prematurely by one of the scouts, and lasted until nightfall—after the desultory manner of Indian mountain fights, where you fire at a tree-trunk or lichened rock, or at some black, red-bound head that shoots up quick as a prairie dog's and is gone again, and where you follow the tactics of the wary Apache in so far as you may. The curious part of it is that you beat him at his own game every time. It is always the troops that lose the least heavily!
  • 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 looked at her uncomfortably. "I am going to get you out of this, up into the mountains somewhere," he said abruptly; "you look peaked."
