TWO:"And he's layin' very low over in a tent there?"Not exactly comprehending what was going on, but thinking that the time for them to act had come, the four boys to whom Si had given the duty of making the rush with the log to break down the door, came bolting up, shouting to their comrades:

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:He put that thought away: it was too much and too large. The one certain thing was that in five days' time (whenever that was) he would know more. In five days they would all meet again."So it isn't plants," he said. "It isn't any more than the Alberts and working with them. You want to do anything to get away from themanything that won't remind you you have to go back."
  • 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:But he kept his hand at his side. Touching the tree, at that moment, was wrong. There were the old rules, the true rules, and to think of them made him feel better.

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

THREE:"I know we was," whimpered little Pete as he capped a gun and handed it to Shorty; "but we couldn't stay when we heard the yelling and shooting. We was so scared that we was afraid to stay there, so we hunted you up, and"
  • 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:"I'm afraid I don't quite see that," Dward put in.

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
