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 indeed seemed evident that some bold measure was contemplated, and Richard's suggestion respecting the monk was about to be acted upon, with only a prudent hint from Sir Robert Hales not to provoke the Commons to desperation, when De Boteler's page approached his master.
  • 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:"It's all over," said Byles, in a disappointed tone; "but the arrow may answer our purpose where it is. Take up the barrow and fly, but keep in the shade of the trees."Then suddenly a great, a magnificent, a triumphant idea struck him. He nearly staggered under the force of it. He was like a general who sees what he had looked upon hitherto as a mere trivial skirmish develop into a battle which may win him the whole campaign. He spoke almost faintly.

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

THREE:"I'd rather not," said Naomi, shuddering.Should you do me to death with your dark treacherie?
  • 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:"That's righthave the courage of your earthiness. But don't try to make me think that when you look out[Pg 218] of the window at Boarzell, you don't see the sky beyond it."
