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.

  • 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:Thats so, Larry.

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

THREE:It was certainly not apparent, on the face of it, how the thing was to be done, but the captain explained. "I've been stationed here, you know, and I know the roads. We are about a half a mile or more from where the Stanton road to the railway crosses the lava. It is narrow and rough, and about from three-quarters of a mile to a mile wide, but cavalry can go over it without any trouble. I can take my troop over, and then the Indians will be hemmed in between us. We might capture the whole band."
  • 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:Once credited with a continued existence, the departed spirit would not remain in the Hades or the Elysium provided for it by the justice or the piety, of the survivor, but persisted in returning to this world and manifesting a most uncomfortable interest in its affairs; or, even if willing to remain at rest, it was liable to be dragged back by incantations, and compelled to reveal the secrets of futurity at the bidding of an unprincipled magician. What science and good feeling combined have proved unable to keep down among ourselves, naturally raged with unmitigated virulence at a time when the primitive barbarism and superstition were only covered over by a crust of culture which at many points was growing thinner every day. Among Latin writers, the younger Pliny, Suetonius, and Apuleius, among Greek writers, Plutarch, Pausanias, Maximus Tyrius, Philostratus, and Dion Cassius, afford unequivocal evidence of their belief and the belief of their contemporaries in ghostly apparitions; and Lucian, while rejecting ghost-stories on his own account, speaks as if they were implicitly accepted even in philosophical circles.372 Still more abundant is the evidence proving the frequency of attempts made to evoke spirits by means of magical incantations. Horaces Canidia boasts that she can raise the dead even after their bodies have been burned.373 Lucan describes the process of conjuring up a ghost at length; and it is thought that he inserted the whole scene in his poem as a satire on the emperor Nero, who is known to have been addicted to such practices, as were also his successors, Didius Julianus, Caracalla, and Elagabalus. And that the same art was cultivated by private persons is clear from the allusions made to it by Quintilian, Apuleius, Tertullian, and Heliod?rus.374
