TWO:The Agency man thought a question would not commit him. He had not been round at that time, and he asked for information. The lieutenant gave it to him.

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:Well, the dinner was being got ready when you sent for us, remarked the captain.
  • 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:[Pg 69]

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

THREE:He sat down cross-legged on the ground, facing her. "I've got plenty of time, my dear woman. I can stop here all day if you can, you know," he assured her. Afterward he made a painting of her as she had sat there, in among the rocks and the scrub growth, aged, bent, malevolent, and in garments that were picturesque because they were rags. He called it the Sibyl of the Sierra Madre. And, like the Trojan, he plied her with[Pg 240] questionsnot of the future, but of the past. "Well," he said, "are you going to answer me?"You said we couldnt get away to tell anybody anyway, Sandy said, but he was compelled to admit to himself that although anyone might write such a lettereven Jeff!the postmark was Los Angeles and the enclosure had every appearance of sincerity.
  • 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:Come onget in! Larry urged. I can fly this crateand well see what theyre going to do!

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