TWO: P.S.I most humbly beg your majesty not to speak of this323 to the queen-mother, as perhaps she would not approve of the step we are now taking.

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: I waver between hope and fear of paying my court to you. I hope it might still be at Berneck, if you could contrive a road into the Nürnberg highway again, avoiding Baireuth; otherwise I dare not go. The bearer, Captain Knobelsdorf, will apprise you of every particular. Let him settle something that may be possible. This is how I stand at present: instead of having to expect some favor from the king, I get nothing but chagrin. But what is more cruel upon me than all is that you are ill. God, in his grace, be pleased to help you, and restore that health which I so much wish for you.
  • 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 mountain range upon the south, which separated Silesia from the realms of the Queen of Hungary, was three or four hundred miles long, with some twenty defiles practicable for the passage of troops. The French minister Valori urged Frederick to guard these passes. This was impossible; and the self-confidence of the Prussian king is revealed in his reply: My friend, if you wish to catch the mouse, you must not shut the trap, but leave it open.

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

THREE:That is not the question, I answered. The question is, whether such a being as God can, or can not, give existence to what, as yet, has none.
  • 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:Do you see the man in the garden yonder, sitting, smoking his pipe? said he to me. That man, you may depend upon it, is not happy.
