TWO:"Say, Alf, did you see me salt that feller that's bin yellin' and cussin' at me over there? He's cussin' now for something else. I think I got him right where he lived."

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:Cadnan imagined a parade of new truths, a store of knowledge that would lay all his questions to rest and leave him, as after a meal, entirely satisfied. He went back to work and contemplated the first of the truths: he was to be like the machine. He promised himself he would try to imitate the machine, doing only what the masters ordered. And for the rest of that day, indeed, life seemed to make perfect calming sense.
  • 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:"You little fool, you knowed about as much about them cards as they know of ice-water in the place where Jeff Davis is goin'. Pete, I'm goin' to be a second father to you.""Here she goes, I guess," he continued, as a bugle sounded at headquarters. "Everybody git ready to jump at the word, and not stop goin' till we're inside the works."

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:After the members were duly seated according to rank, with Maj. Truax at the head of the table, Lieut. Bowersox read the order for holding the court, and called the names of the members. He then said:

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