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: My dear Son Fritz,I am glad you need no more medicine. But you must have a care of yourself some days yet, for the severe weather gives me and every body colds. So pray be on your guard.
  • 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: General Finck gets a difficult commission. The unlucky army which I give up to him is no longer in a condition to make head against the Russians. Haddick will now start for Berlin, perhaps Loudon too.136 If General Finck go after these, the Russians487 will fall on his rear. If he continue on the Oder, he gets Haddick on his flank. However, I believe, should Loudon go for Berlin, he might attack Loudon and beat him. This, if it succeeded, would be a stand against misfortune, and hold matters up. Time gained is much in these desperate circumstances. C?per, my secretary, will send him the news from Torgau and Dresden. You must inform my brother137 of every thing, whom I have declared generalissimo of the army. To repair this bad luck altogether is not possible. But what my brother shall command must be done. The army swears to my nephew. This is all the advice in these unhappy circumstances I am in a condition to give. If I had still had resources, I would have staid by them.

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

THREE:On the 6th of July, the trunk having arrived, the volume of poems was recovered and Voltaire was allowed to go on his way. His pen, dipped in gall, was an instrument which even a monarch might fear. It inflicted wounds upon the reputation of Frederick which will probably never be healed. Four years passed away, during which Voltaire and Frederick were almost entirely strangers to each other.
  • 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:

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