TWO:"If you open the lid," explained the Clockwork man (and at the sound of that human[Pg 162] voice the doctor jumped violently), "you will see certain stops, marked with numbers.""Yes, you've secured a furlough."

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:"That was not play, Mr. Smith," Miss Harper had begun to respond, when a voice across the sedge-field called with startling clearness,"Yes," I replied, "in that direction."
  • 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:There was a certain amount of applause, followed by an embarrassing silence. Presently someone threw another ball out into the field, and the game was resumed. But the Clockwork man treated Tanner's next delivery, which was a fast one, in exactly the same manner. Again nobody could say exactly what happenedfor the action was swifter than the quickest eye could followbut the ball disappeared[Pg 27] again, this time in the direction of a fringe of poplars far away on the horizon. Again there was a lull, but the applause this time was modified. Another ball was supplied, and this also was dispatched with equal force and in a third direction, almost unanimously decided by the now bewildered spectators to be the flagstaff of the church that stood in the middle of the High Street, Great Wymering.Then suddenly all surmise and speculation was expunged from his mind, for no longer the clack of the typewriting machine came from next door. He heard the stir of a chair pushed back, and the rattle of a door handle. Norah was coming; who was of greater concern than all his thoughts about her.... And he was going to give her no quarter: she would have to introduce the subject of her feelings with regard to his niggardly hospital-subscription herself. He knew something of her pride from the affair of the book-plate, and he longed to see her take that armour off.

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

THREE:But there was an unforeseen result to this transaction, for it was soon noised about among the small boys that the foreigners were giving fish-hooks for tortoises; and as there was a good supply of the latter, and not a good one of the former, there was a public anxiety to benefit by the newly opened commerce. In less than half an hour there was a movement in the market that assumed serious importance, and Frank found[Pg 195] himself in the character of a merchant in a foreign land. He became the owner of nearly a dozen of the kindred of his first purchase, and would have kept on longer had not his stock-in-trade given out. The guide took the purchases in charge, and they followed the fate of the pioneer in the business in finding their way to the cooking-pot. When the traffic was ended, and the Japanese urchins found that the market was closed, they pronounced their "sayonaras" and withdrew as quietly as they had come.
  • 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:The Doctor took another glance at the barometer, and discovered something. The mercury was stationary!

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