TWO:The figure stopped with startling suddenness, but offered no explanation.Lady Keeling will be only too gratified, said her husband.

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:I am sure you are very useful to Mr Keeling, she said, in helping to arrange his books, and it must be a great treat to you to have access to so large a library, if you are fond of reading.
  • 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:"We have a theory of relativity," Allingham ventured.

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

THREE:As the train approached the spot where the herd was crossing the track, the locomotive gave its loudest and shrillest shrieks. The noise[Pg 44] had the effect of frightening the buffaloes sufficiently to stop those which had not crossed, and in the gap thus formed the train moved on. The boys were greatly interested in the appearance of the beasts, and Frank declared he had never seen anything that looked more fierce than one of the old bulls, with his shaggy mane, his humped shoulders, and his sharp, glittering eyes. He was quite contented with the shelter of the railway-car, and said if the buffalo wanted him he must come inside to get him; or give him a good rifle, so that they could meet on equal terms."Play," said the umpire.
  • 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:It was also manifest that the Clockwork man was capable of almost limitless adaptability. Several of the stops produced only slight changes or the first beginnings of some fundamental alteration of structure. Usually these changes were of a sufficiently alarming character to cause the Doctor immediately to check them by further experiments. The Clockwork man seemed to be an epitome of everything that had ever existed. After one experiment he developed gills. Another produced frightful atavistic snortings. There was one short-lived episode of a tail.
