TWO:The next day tempest scattered the approaching transports. Sir John thought the storm sufficient excuse for not pursuing; but the winds followed the invaders, and blowing directly from London towards Dunkirk, dispersed the French transports, sank some of the largest of them with all their men, wrecked others on the coast, and made the rest glad to recover their port. Charles waited impatiently for the cessation of the tempest to put to sea again, but the French ministers were discouraged by the disaster, and by the discovery of so powerful a British fleet in the Channel. The army was withdrawn from Dunkirk, Marshal Saxe was appointed to the command in Flanders, and the expedition for the present was relinquished.

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.

  • 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:"Where do you want me to go?" he almost moaned, and finished with an oath.All rightthank you. Ill keep cooland do my best.

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

THREE:Cant you guess?
  • 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).
