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:Sir Robert had remarked the sudden flush, and then the death-like paleness, which had passed over Holgrave's face, as his glance fixed upon Byles; and perceiving that, as his dead mother was spoken of, he became excessively agitated, he ordered his page to carry him another cup of wine; and the two criminals being removed, De Boteler continued,The man he addressed consented, and their steps were soon lost in the distance.
  • 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:"F?ather, it wur an accident."

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

THREE:All Peasmarsh went to the Fair. It was a recognised holiday. All farm workexcept the most barely necessarywas put aside, and the ploughman and dairymaid rollicked with their betters. The road across Boarzell was dark with them, coming from all quartersPlayden, Iden, Beckley, Northiam, BodiamOld Turk's Farm, Baron's Grange, Corkwood, Kitchenhoureven from Blackbrook and Ethnam on the Kentish border.
  • 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 did not have to wait long. A few days later he was told that somebody wanted to see him, and in the parlour found his daughter Tilly.
