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:She sat with her jaw hanging, staring at him, baffled,[Pg 262] and he went on. "I've got Lawton jailed, as I was saying. I'll have you out of the country in three days, and as for Mrs. Lawton, I'll keep an eye on her. I'll know where she is, in case I need her at any time. But I'm not fighting women."
  • 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:"He's coming back from Tombstone with some money, ain't he?""Who is there to marry hereabouts? And always supposing there were some one, I'd be sent off on a scout next day, and have to ship her back East for an indefinite time. It would be just my blamed luck."

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

THREE:Then she tried to read, but the whisper of savagery was in the loneliness and the night. She sat with the book open in her lap, staring into a shadowy corner where there leaned an Indian lance, surmounted by a war bonnet. Presently she stood up, and stretched her limbs slowly, as a beast of prey does when it shakes off the lethargy of the day and wakens for the darkness. Then she went out to the back of the tents.
  • 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:Cairness himself had speculated upon that subject a good deal, and had noticed with a slight uneasiness the ugly looks of some of the ranch hands. "They are more likely to have trouble in that quarter than with the Indians," he said to himself. For he had seen much, in the ranks, of the ways of the disgruntled, free-born American.

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