TWO:To his physicians, who were doubtful respecting the nature of his disease, he said, If Doctor Gazelli were here you would soon know what is my complaint. As it is, you will only learn after you have dissected me.

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:
  • 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 queen was at this time in a delicate state of health, and anxiety and sorrow threw her upon a sick-bed. The king, who felt as much affection for Phiekin as such a coarse, brutal man could feel for any body, was alarmed; but he remained obdurate. He stormed into her room, where, in the fever of her troubles, she tossed upon her pillow, and obstreperously declared that Wilhelmina should be married immediately, and that she must take either Weissenfels or Schwedt. As both mother and daughter remained firm in their refusal to choose, he resolved to decide the question himself.

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

THREE:Charles, feeling keenly the bereavement, and alarmed for the health of his wife, whom he loved most tenderly, hastened to his home in Brussels. The prince and princess were vice-regents, or joint governors of the Netherlands. The decline of the princess was very rapid. On the 16th of December, the young prince, with flooded eyes, a broken-hearted man, followed the remains of his beloved companion to their burial. Charles never recovered from the blow. He had been the happiest of husbands. He sank into a state of deep despondency, and could never be induced to wed again. Though in April he resumed, for a time, the command of the army, his energies were wilted, his spirit saddened, and he soon passed into oblivion. This is but one among the countless millions of the unwritten tragedies of human life.385 This good old man died in Berlin on the 24th of August, 1777, eighty-eight years of age.
  • 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).
