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:Frank opened his eyes with astonishment. Fred did likewise.No such proposition was submitted to him.
  • 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:He put the block down, laid the two impressions on the top of it, and turned over the leaves of his cheque-book in order to pay for the thing at once. But she picked up her work, and without a word began wrapping it up in the paper she had just taken off it. Already he knew he had made a blunder, and the blunder was the act of a cad. It had been his business to ask the price beforehand, if he wanted to know it, not to{124} quarrel with it afterwards. But the cad in him had full possession just then.

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

THREE:
  • 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:Alice Keeling was sitting close to the window of her mothers room making the most of the fading light of a gray afternoon at the end of October, and busily fashioning leaves of gold thread to be the sumptuous foliage of no less sumptuous purple pomegranates, among which sat curious ecclesiastical fowls, resembling parrots. The gold thread had to be tacked into its place with stitches of gold silk, and this strip of gorgeous embroidery would form when completed part of the decoration of an altar-cloth for the church which till but a few weeks ago, had not even had an altar at all, but only a table. Many other changes had occurred in that hitherto uncompromising edifice. The tables of commandments had vanished utterly; a faint smell of incense hung permanently about the church, copiously renewed every Sunday, candles blazed, vestments flashed, and a confessional, undoubtedly Roman in origin, blocked up a considerable part of the vestry. But chief of all the changes was that of the personality of the vicar, and second to that the state of mind of the parish in general to which, taking it collectively, the word Christian could not properly be applied. But taking the parish in sections, it{98} would not be in the least improper to apply the word ecstatic to that section of it to which Alice Keeling belonged, and the embroidery on which she, like many other young ladies, was employed was not less a work of love than a work of piety. As the blear autumnal light faded, and her mother dozed quietly in her chair, having let her book fall from her lap for the third time, Alice, short-sightedly peering at the almost completed leaf, would have suffered her eyes to drop out of her head rather than relinquish her work. She was sewing little fibres and shreds of her heart into that pomegranate leaf, and it gave her the most exquisite satisfaction to do so.The Federal expanded with surprise and then with austere pleasure. He glanced toward his five men galloping back to him having found no enemy, and then at his column, which had just halted. Frowning, he motioned the advance guard to the road again and once more hailed Ferry while he pointed at me. He straightened and swelled still more as he began his question, but as he finished it a smile went all over him. "Is that your entire present force?"
