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:Alices banns had never been given out by anybody, and a physiognomist might hazard the conjecture that they never would be, for she had in her face, with its short-sighted eyes, high cheekbones, and mouth that looked as if it had got unbuttoned, that indescribable air of old-maidishness which fate sometimes imprints on the features of girls still scarcely of marriageable age. They do not, as Alice did not, seem to be of the types from which wives and mothers are developed. A celibacy, tortured it may be, seems the fate inexplicably destined for them by the irony of Nature who decreed that they should be women, and they discharge their hearts in peevishness or in feverish activities. Alice was inclined to the more amiable of these safety-valves, but she could be peevish too.
  • 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.

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

THREE:I guffawed in derision. "And she didn't even have to tell you so! She can't even hide its deadly intensity from the casual bystander! haw! haw! haw! And it's all the outcome of a three-days acquaintance! It beats Doctor Swiftgrow's Mustache Invigor'--aw, haw! haw!" "Oh, you think so? Pity you couldn't get a few barrels of it--aw, haw! haw!" said Harry, and my laughter left off where his began. But, some way hurting his hand, he, too, stopped short. I drew my horse back.
  • 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:Well, Im sure I should be puzzled to name a pleasanter evening she said. I thought it all quite brilliant, though Im sure I claim no share in its success except that I do think I gave you all a very good dinner. Im sure I never tasted a better bit of spring salmon than that. Was it not lucky it caught my eye this afternoon. And the slippers, too, Alice! It was quite a little comedy: I am sure I have seen many less amusing scenes in a play. To introduce everybody to his slippers! That was a good idea, and it must have been quite ex tempore, for I am certain he did not know what was inside the packet till he came to the last wrappings."Well, I reckon I'll stop all night." I began to move on. His eyes followed greedily.
