TWO:But they were at the port of Osaka and Kioto, and their thoughts were[Pg 271] turned towards those important cities. There was no difficulty in going there, as the railway was in operation to Osaka, twenty miles, and to Kioto, thirty miles farther on. But Frank was seized with an idea, which he lost no time in communicating to his friends. It was this:

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:Its an un-Christian feeling, maybe, to have about anybody, said he, but thats your mothers affair and not mine. She may feel about me what she pleases, but I wish her to know she must speak properly to me, or not speak at all. I shouldnt have referred to it again, unless you had begun, but now that youve begun its best you should know what my opinion on the subject is. Before the children, too: I had better manners than that when I was in the fish-shop myself.I attempted an evasion. "Oh--a blanket on the ground--face covered up in it from the mosquitos--is really--"
  • 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:"I see the man," he began, timidly, "I see 'im as I was going along the path to Bapchurch.""You see," Frank continued, "that you know by the compass exactly in what direction you are going; then, if you know how many miles you go in a day or an hour, you can calculate your place at sea.

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

THREE:Her rejoinder came in a low, grieved monotone: "Did you say had hoped?"They were off again early in the morning, and in a little while came to the banks of a river which they were to cross. Frank looked for a bridge, and saw none; then he looked for a ferry-boat, but none was visible.
  • 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:At the appointed time they were off. They went through the foreign part of Yokohama, and through the native quarter, and then out upon the Tokaido. The boys were curious to see the Tokaido, and when they reached it they asked the Doctor to halt the jin-riki-shas, and let them press their feet upon the famous work of Japanese road-builders. The[Pg 157] halt was made, and gave a few minutes' rest to the men that were drawing them, and from whose faces the perspiration was running profusely.

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