TWO:"Goodness!" murmured Monty Scruggs, with colorless lips, as the regiment came into line and moved forward to the battery's line of caissons at the bottom of the hill. "I'm so glad I didn't enlist in the artillery. I don't see how anybody up there can live a minute."

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:Shorty was rubbing it in on his old tormentor in hopes to provoke him to a fight. But the cowed man was too fearful of publicity just then. He did not know what might be held in reserve to spring upon him. He shambled away, muttering:
  • 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 aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.

THREE:"Great Goodness, Shorty," said the Deacon, "is that you?"
  • 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:"She can't." His hands fell to his sides. "Neither can you, Cadnan. I'mlook, there's a guard stationed right down the corridor, watching this door every second I'm here. There are electronic networks in the door itself, so that if you manage somehow to open it there'll be an alarm." He paused, and began again, more slowly. "If you go past me, or if you get the door open, the noise will start again. You won't get fifteen feet."
