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:If these words are true, which Milton places in the lips of the apostate fiend, it is appalling to think of the ungoverned and ungovernable spirit with which the king entered the unseen world. We know not that there is any power in the alembic of death to transform the character; and certain it is that if Frederick William carried with him to the abode of spirits the same character which he cherished in this world, there are but few who could be rendered happy by his society. But we must leave him with his God, and return to the stormy scenes upon which his son now entered.I assure you he is a prince who has talent, but who will be the slave of his passions, and will like nobody but such as encourage him therein. For me, I think all princes are cast in the same mould. There is only a more and a less.
  • 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:It is late. I wish you had done.

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

THREE:Prince Leopold was keenly wounded by this reproof. Though he uttered not a word in self-defense, he was ever after, in the presence of his majesty, very silent, distant, and reserved. Though scrupulously faithful in every duty, he compelled the king to feel that an impassable wall of separation had risen up between them. He was seeking for an honorable pretext to withdraw from his majestys service.
  • 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.
