TWO:Jeff chews gum, he mused. He pretended not to know any was in this amphibian. But its gone! Well, he told himself, Ill watch and see what hes up to. Hell give himself away yet!

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:Something new has come up, sir. I was waiting there by my ship a good while back, and I heard another one cruising and spiraling, shooting the field, I guess, because he came in and set down. My crate, just the way you ordered, was down by the grove, not in plain sight in the middle of the course. But Jeff set his ship down, left the engine running, and went off. I stayed hid to see what would happen, but when he didnt come back, I thought Id better go and find youand see if it meant anything to you.On extending our survey still wider, we find that the existence of a thing everywhere depends on its unity.462 All bodies perish by dissolution, and dissolution means the loss of unity. Health, beauty, and virtue are merely so many different kinds of harmony and unison. Shall we then say that soul, as the great unifying power in Nature, is the One of which we are in search? Not so; for preceding investigations have taught us that soul is only an agent for transmitting ideas received from a higher power; and the psychic faculties themselves are held together by a unifying principle for which we have to account. Neither is the whole sum of existence the One, for its very name implies a plurality of parts. And the claims of the Nous to that distinction have been already disproved. In short, nothing that exists can be the One, for, as we have seen, unity is the cause of existence and must therefore precede it.
  • 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:See that wing? he pointed. It sticks up, and its higher than our own tankand if theres a wing-tank, and I think a seaplane would have them241

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

THREE:
  • 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:You would spoil it! Larry was unable to keep from being annoyed, almost angry, because Jeff had spoiled a surprise.
