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: Voltaire.There still remained to Frederick twenty-three years of life. He now engaged very vigorously in the endeavor to repair the terrible ravages of war by encouraging agriculture, commerce, and all useful arts. He invited the distinguished French philosophers Helvetius and DAlembert to visit his court, and endeavored, though unavailingly, to induce them to take up their residence in Berlin. They were both in sympathy with the king in their renunciation of Christianity.
  • 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:DESTROYING THE LETTERS.

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

THREE:Yes, the king replied. I swear it to you, DArget. In a word, I want to have some good of my life. What are we, poor human atoms, to get up projects that cost so much blood!
  • 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:The queen remained bitterly unreconciled to the marriage of Wilhelmina with any one but the Prince of Wales. Stung by the sense of defeat, she did every thing in her power, by all sorts of intrigues, to break off the engagement with the Prince of Baireuth. When she found her efforts entirely unavailing, she even went so far as to take her daughter aside and entreat her, since the ceremony must take place, to refuse, after the marriage, to receive the Prince of Baireuth as her husband, that the queen might endeavor to obtain a divorce.
