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:They were high among the mountains, and here and there in the shadows of the rocks and pines were patches of snow, left even yet from the winter. By all the signs the trail was already more than half a day old.[Pg 24]
  • 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:[Pg 69]

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

THREE:Then there came a chuckling scream of baby laughter and a soft reproach, spoken in Spanish, from across the hall. She stood up and poured the coffee, but before she took her own she went out of the room and came back in a moment, carrying her small son high upon her shoulder.Pending her arrival, Landor brought himself to look[Pg 16] upon it as his plain duty and only course to marry her. It would save her, and any man who might otherwise happen to love her, from learning what she was. That she might refuse to look at it in that way, did not much enter into his calculations. It required a strong effort for him to decide it so, but it was his way to pick out the roughest possible path before him, to settle within himself that it was that of duty, and to follow it without fagging or complaint. He dreaded any taint of Apache blood as he dreaded the venom of a rattler. He had seen its manifestations for twenty odd years, had seen the hostile savage and the civilized one, and shrank most from the latter. But he had promised Cabot to do his best by the waif, and the best he could see was to marry her. There was always before him, to urge him on to the sacrifice, the stalwart figure of his boyhood's friend, standing forsaken in the stretch of desert with the buzzards hovering over him in the burning sky. He permitted himself to hope, however, that she was not too obviously a squaw.
  • 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 went upon the sick report at once, and for three days thereafter raved of crucified women with fair hair, of children lying dead in the ca?on, of the holes in his boot soles, and a missing aparejo, also of certain cursed citizens, and the bad quality of the canned butter.
