TWO:IV."On August 15th a fierce fight took place between the French troops on the left bank of the Meuse and the Germans who approached from the east. The Germans were defeated, put to flight, and chased by the French, who crossed the river. On that day the town was not damaged much. Some houses were destroyed by German howitzers, which were undoubtedly aimed at the French regiments on the left bank. One Red Cross helper who lived at Dinant was killed by a German bullet when he was taking up one of the wounded.

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:"Now I have got you, murderess!" Hetty cried.
  • 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:Lawrence desired nothing better. In a few minutes the stones lay on the table. The novelist picked them up, and took from his pocket a small file which he coolly rubbed on the facet of two of the larger stones. Maitrank smiled. Any diamond would stand that test. With a grave look, Lawrence handed the stones back--the tested diamonds were dull and flat.But it was only Mamie whimpering and crying for her. The child was awake and sitting up in bed, whilst the nurse still slept. Mamie was hot and feverish.

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

THREE:They heard the strange, hollow sound again, seeming to come from the metal wall, but impossible to locate at once because of the echo.
  • 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:"Well?" Lalage burst out, furiously. "Why don't you speak; what have you got to say before I put the knife into your heart?"

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