TWO:THE JUNK AT ANCHOR. THE JUNK AT ANCHOR.

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:"Certainly, my boy," the Doctor answered, "there are thirteen rivers and canals in Osaka, so that the city has an abundance of water communication. The streets are generally at right angles, and there are more than a hundred bridges over the water-ways. From this circumstance Osaka has received the name of the Venice of Japan, and she certainly deserves it. Formerly her commerce by water was very great, and you would see a large fleet of junks in the river below the town. The opening of the railway to Kobe has somewhat diminished the traffic by water; but it is still quite extensive, and employs a goodly amount of capital.Reveill was sounding as I entered the camp. In the middle of my story to the General--"Saddle my horse," he said to an attendant, "and send Mr. Gholson to me. Yes, Smith, well, what then?"--I resumed, but in a minute--"Mr. Gholson, good-morning. My compliments to Major Harper, Mr. Gholson, and ask him if he wouldn't like to take a ride with me; and let me have about four couriers; and send word to Colonel Dismukes that I shall call at his headquarters to see him a moment, on my way out of camp. Now, Smith, you've given me the gist of the matter, haven't you? Oh, I think you have; good-morning."
  • 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:Ah, that had not occurred to me, said Keeling.

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

THREE:He climbed quickly up the narrow chalky path, and at the top left it to tramp over the turf. Here he was on an eminence that commanded miles of open country, empty and yet brimful of this invasion of renewed life that combed through him like a swirl of sea-water through the thickets of subaqueous weed. His back was to the cup of hills round which Bracebridge clustered, and turning round he looked at it with a curious sense of detachment. There were the spires of the Cathedral, and hardly less prominent beside them the terra-cotta cupolas of the Stores. He wanted one as little as he wanted the other, and turned westwards, where the successive lines of downs stretched away like waves of a landless sea. Then he stopped again, for from a tussock of grass not fifty yards from him there shot up with throbbing throat and down-beating wings a solitary lark.{233} Somewhere in that tussock was the mate to whom it sang.He might have known by looking a trifle more narrowly; I saw plainly, thrillingly, who he was; but his attention was diverted by some signal from the men he had sent to the fringe of cane; they had found the tracks of horses leading through the canes into the corn. But now he hailed me again. "Here, you! what are you doing at that fence? Who are you?"
  • 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:Even this did not hurt him. He was rather amused than otherwise.

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