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:��Well, what Mamma will do unless you help her this Christmas, is more than I can tell,�� she said. ��Coal is up now to winter prices, and Mamma��s cellar is so small that she can��t get in enough to last her through. And it��s little enough that I can do for her, for with John at home it��s like having two young lions to feed, and how to save from the house-money you give me I don��t see. I dare say it would be better if Mamma got rid of Blenheim for what it would fetch and went into furnished lodgings.��
  • 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:when, just as our last note died among the trees one of us cried, "Listen!" and through the stillness there came from far away on our right the last three measures of a bugle sounding The March.��I��ve been thinking, dear,�� she said, ��that it would be but kind to ask Mr Silverdale down to Brighton while we are there. He looks as if a holiday would do him good. I would take a nice room for him in the hotel, and of course he would use our sitting room. Of course, I should make it quite clear to him that he was my guest, just as if he was staying with us here. Such walks and{224} talks as you and he could have! What do you think of that for a plan?��
  • 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).
