TWO:"Because," said the Doctor, trying hard to control the twitching of his features, "it's too terrible. What I have seen to-night is not fit for mortal eye to behold. It's inhuman. It's monstrous!"

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:"Then you were at the front."
  • 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:"No, I'm not," grumbled the Doctor, "I've had enough of this wild-goose chase. And besides, it's nearly dinner time."

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

THREE:But a second later there was stony silence. For the thing that happened next was as unexpected as it was startling. Nobody, save perhaps Dr. Allingham, anticipated that the Clockwork man was capable of adding violence to eccentricity; he looked harmless enough. But apparently there lurked a d?monic temper behind those bland, meaningless features. The thing happened in a trice; and all that followed occupied but a few catastrophic seconds. The umpire had stepped up to the Clockwork man in order to explain to him that he was expected to retire from the wicket. Not hearing any coherent reply, he emphasised his request by placing a hand suggestively on the other's[Pg 37] shoulder. Instantly, something blade-like flashed in the stammering air, a loud thwack broke upon the silence, and the unfortunate umpire lay prostrate. He had gone down like a log of wood.
  • 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: "There have been several men around the hotel trying to sell things to us, and we have been looking at them. One thing I am going to[Pg 90] get and send in this letter is a box of Japanese pictures. They are not photographs, but real drawings by Japanese artists, and printed on Japanese paper. You will see how soft and nice the paper is; and though the pictures look rough, they are very good, and, above all things, they are truthful. I am going to get as many different ones as I can, and so I think you will be able to get a good idea of the country as the natives see it themselves. They have these pictures showing all their ways of lifehow they cook their food, how they eat it, how they work, how they playin fact, how everything is done in this very curious country. The Japanese make their drawings with very few lines, and it will astonish you to see how much they can express with a few strokes of a pencil. Here is a[Pg 91] picture of a horse drawn with seven strokes of the artist's finger-nail dipped in ink, and with a few touches of a wide brush for the mane and tail. Do you think my old drawing-master at home could do the same thing?

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