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:We have seen with what freedom Carneades discussed the foundations of morality. It is now evident that in so doing he did not exceed the legitimate functions of criticism. No one at the present day looks on Prof. Bain and Mr. Henry Sidgwick as dangerous teachers because they have made it clear that to pursue the greatest happiness of the greatest number is not always the way to secure a maximum of154 happiness for oneself. The really dangerous method, as we now see, is to foster illusions in early life which subsequent experience must dispel."No you don't," said Lawrence coolly. "Of course, it would be a very dramatic finish to the night's adventure, but I can't permit it. Go easy."
  • 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:Screw-cutting machines may be divided into modifications as follows:(1) Machines with running dies mounted in what is called the head; (2) Machines with fixed dies, in which motion is given to the rod or blank to be threaded; (3) Machines with expanding dies which open and release the screws when finished without running back; (4) Machines with solid dies, in which the screws have to be withdrawn by changing the motion of the driving gearing; making in all four different types."4. Who serve the enemy as a spy, lodge hostile spies, hide them or aid them.
  • 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:"In that case I shall ask you to listen to mine with what patience you can. I have no desire to be in the least vindictive; it is a matter of indifference to me whether you stand in the dock or not. Personally I would go out of my way to save any woman from that indignity. But if you will have it you must."3. The valve must move after the hammer stops.

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