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:"What is the use of writing up our Canton experiences," said Frank, "till we know what we are to do? If we go home by San Francisco, we will have plenty of time on the steamer; and if we go on to the west, we will have to go by steamer too; and then we will have time enough between Hong-kong and the first port we stop at. Why should we be in a hurry to write up our account, when, in any case, we shall have the time to do so while we are at sea?"
  • 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:The Doctor sat upon the couch, with his hands limply hanging between his knees. He was conscious of perspiration, but made no attempt to wipe his forehead. His heart was knocking hard against his ribs, and occasionally missing a beat. He noticed this fact also, but it caused him little concern. Now and again he looked swiftly at the Clockwork man and studied his extraordinary method of mastication, the rapid vibratory movement of the jaws, the apparent absence of any kind of voluntary effort.
  • 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:JAPANESE BOWL. JAPANESE BOWL.He glanced up at her photograph on the mantelpiece. If there was a flaw in the composition of her fair, Saxon beauty, it was that the mouth was a little too large and opened rather too easily, disclosing teeth that were not as regular as they should be. But nature's blunder often sets the seal on man's choice, and to the Doctor this trifling fault gave warmth and vivacity to a face that might easily have been cold and impassive, especially as her eyes were steel blue and she had no great art in the use of them. Her voice, too, often startled the listener by its occasional note that[Pg 125] suggested an excitability of temperament barely under control.
