TWO:Dolt that I was, I would have drawn her close, but she put me off with an outstretched arm and forbidden smile. "No!--No! this is a matter of life and death."I flushed with indignation, and my eye retorted to his that I had only followed his example. His answer was a smile. "You, also, have been guessing, eh?" he said, and when I glowed with gratitude he added,

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:"We think we want to write home now, Doctor," said Frank, "and wish to know if you approve of our doing so to-day."
  • 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:"But how did you come by these?" questioned Gregg, who was still holding the hat and wig.

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

THREE:He cut her short.This appeal was more successful. Something in the simple dignity of Keelings reply had silenced her, and she was led away like a wicked little elephant between her daughter and Alice. Not one word did Keeling say till they had left the room, and then, though his usual allowance of port on Sunday was one glass after lunch and two after{29} dinner, he helped himself again and pushed the bottle towards Hugh.
  • 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).
