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:Alice could do better than give him little bits, thanks to her excellent memory and her practice this afternoon, and in addition to several Songs Without Words, gave him a couple of pretty solid slow movements out of Beethovens Sonatas. It was not altogether her fault that she went on so long, for once when she attempted to get up, he said quite aloud so that everybody could hear, You naughty girl, sit down and play that other piece at once. But when eventually the concert came to a close, he pressed her hand for quite a considerable time behind the shelter of the piano, and said almost in a whisper, Oh, such rest, such refreshment! Then instantly he became not so much the brisk man of the world as the brisk{61} boy of the world again, and playfully insisted on performing that remarkable duet called Chopsticks with her, and made her promise that if Mr Keeling lost all his money, and she had to work for her living, she would give him lessons on the piano at seven-and-sixpence an hour. There was a little chaffering over this, for as a poor priest he said that he ought not to give more than five shillings an hour, while Mrs Keeling, joining in the pleasantries, urged Alice to charge ten. The only possible term to the argument seemed to be to split the difference and call it seven-and-sixpence, cash prepaid.... Mr Keeling was appealed to and thought that fair. But he thought it remarkably foolish also.
  • 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:Alice fixed her faint eyes on her father.

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

THREE:But the Captain answered headily; "No, sir! I've tried that twice already; this time I'll cut them in two and be in their rear at one dash! Bring in your company behind mine, if you choose."I think you are rather brutal, she said. You dont help me out at all.
  • 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:He stood a minute or two at the front door, with broken melodies from Omar Khayyam lingering like fragments of half-remembered tunes in his head. And Thou, beside me singing in the wilderness, was one that sang itself again and again to him. But no one had ever sung to him in the wilderness. The chink of money, the flattering rustle of bank-notes had sung to him in the High Street, and he could remember certain ardours of his early manhood, when the thought that Emmeline was waiting for him at home made him hurry back from the establishment which had been the nucleus-cell which had developed into the acres of show-rooms and passages that he now controlled. But Emmelines presence at home never made him arrive at his work{47} later than nine oclock next morning. No emotion, caused either by Emmeline or ledger-entries, had ever dominated him: there had always been something beyond, something to which perhaps his books and his Sunday afternoon dimly led. And they could scarcely lead anywhere except to the Wilderness where the Thou yet unencountered, made Paradise with singing.... Then with a swift and sudden return to normal consciousness, he became aware that Mrs Goodfords bath-chair was no longer drawn up on the grass below the larches, and that he might, without risk of being worried again, beyond the usual power of Emmeline to worry him, take his cup of tea in the drawing-room before going to evening service.
