TWO:"Can you suppose I should have insulted you by coming here without asking you some favour?"Then, in the magic of the evening, the air was saturated with fragrance; invisible gardenias, amaryllis, and lemon-flowers perfumed the cool night. On every side we could hear the quavering guzla, the sound of tom-toms and tambourines. The streets were brightly lighted up and crowded.

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:
  • 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:

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

THREE:Off at four in the morning, led by a Mongol guide with a broad expressionless yellow face. My steed was a perfect little devil of a horse of a light coffee colour.At the station pilgrims again, bewildered, shouting, rushing about in search of their lost luggage. One group presently emerged from the crowd, led by a man bareheaded, who rang a big bell with great gesticulations, his arms in the air, and the whole party marched off towards the temples in silent and orderly procession.
  • 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:Out of doors, meanwhile, one funeral procession almost trod on the heels of the last; at the latest gleam of day, and out towards the west, above the Field of Burning, a broad red cloud filled all one quarter of the sky.

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
