TWO:The citizen was still there, still holding the candle and shading it, scared out of the little wits he had at the best of times. He was too frightened as yet to curse Brewster and the wary scoundrel back in Arizona, who had set him on to tampering with the military,[Pg 192] and had put up the funds to that end—a small risk for a big gain.

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:But the men did not. It was hardly to be expected that they should, both because the abstract and the ethical are foreign to the major part of mankind, in any case; and also because, with this particular small group of mankind, there was too fresh a memory of a dead woman lying by the bodies of her two children in a smouldering log cabin among the mountains and the pines.
  • 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.

THREE:Thereafter some of the troops sat down at the water-holes along the border to watch, and to write back pathetic requests for all the delicacies supplied by the commissariat, from anchovy paste and caviare to tinned mushrooms and cove oysters. A man may live upon bacon and beans and camp bread, or upon even less, when his duty to his country demands, but it is not in the Articles of War that he should continue to do so any longer than lack of transportation compels.
  • 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:

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