TWO:"Great Scott, what a line," groaned Si, walking along, shoving the boys back, and twisting them around, to get them straight. "Crooked as a pumpkin vine in a cornfield. Here, I told you not to turn your heads, but only your eyes. If you snipes wouldn't gab so much, but listen to what I say, you'd git along better. Silence in ranks. Now, try it over again. Faces straight to the front. Eyes cast to the right, until they catch the buttons on the breast of the second man. Right dress!"

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:It was late in the afternoon before the overworked Surgeon in the field hospital at Chattanooga, in which Si and Shorty were finally deposited, found time to examine them.The news had reached the 200th Ind. that the boys were going home, and they came over in a body to say "Good-by."
  • 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.

  • 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.
