TWO:A passage was instinctively made for the dignitary, who walked majestically on till he stood before the bench, and then pausing, he said in a clear, firm voice

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:A theme unsung by other harps is mineHowever, Europe was disobliging; corn prices hardly rose at all, and Reuben was driven to the unwelcome thought that the only hope of the British farmer was milkat least, that was not likely ever to be imported from abroad.
  • 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:"Quite so, Squire. But it ?un't the cow as I'm vrothered about so much as these things always happening. This ?un't the first 'rag,' as he calls it, wot he's had on my farm. I've complained to you before."A great quiet was wrapped round the house, and a great darkness, pricked by winking stars. The barns were shut, the steamings of the midden were nipped by brooding frostsnow and then the dull movements of some stalled animal could be heard, but only from the yard; in the house there was silence except for the singing fire, and Harry's low muttering which seldom rose into words. Then suddenly there was a knock at the door.

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

THREE:The rest of the family had gone to bed, though scarcely to sleep. Reuben had washed the blood and filth off his face, and had stripped to his shirt, but he felt too sick and restless to lie down. He sat at his window, staring out into the dark gulf of the night.
  • 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.

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