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:Supper was a quiet meal. Old Jury and his invalid wife sat at each end of the table, while Alice did most of the helping and waiting. They seemed a sorry three to Reuben, pale, washed out, and weakly, their eyes bright as birds' with the factitious light of their enthusiasms for things that did not matter. They ate without much appetite, picking daintily at their food, their knives never in their mouths. Reuben found himself despising them as he despised the Bardons.
  • 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:"Because I hate it. It's spoiling your life. It's making a beast and a maniac of you. You think of nothingabsolutely nothingbut a miserable rubbish-heap that most people would be throwing their old kettles on."

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

THREE:"Rose, you queer me."Reuben cursed the base trucksters who had brought it forward, and he cursed the scummy versifier who was its laureatewhose verses appeared daily on six-foot hoardings, and were sung by drunken Radicals to drown his speeches. No one knew who the Radical poet was, for his party kept him a mystery, fearful, no doubt, lest he should be bribed by the other side. Some said that he was a London journalist, sent down in despair by the Liberals at head-quarters. If so they must have congratulated themselves on their forlorn hope, for the tide of events changed completely.
  • 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:Nevertheless, he called at Starvecrow and renewed his impressions of Rose. They did not want much[Pg 251] adjustment; he found her as he had found her that first eveningchildlike in all things save love, indolent, languorous, and yet with gay bursts of spirit which made her charming. He noticed too how well dressed she washe admired her stuff gown and neat buttoned boots, so different from what he was accustomed to see on the feet of his womenfolk; he admired the crinkle and gloss of her hair, so beautifully waved and brushed, and scented with some lotionher hands, too, well kept and white with shining pink nails, her trim muslin collar, the clover scent of her garments ... it was all new, and gave him somehow a vague feeling of self-respect.
