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:"Oh, Ben, don't make me go."She had been a fool to come, and she moved a step or two towards the door. Then suddenly she remembered the anguish which had driven her to Odiam. She had been frantic with grief for her husband and children; only the thought of their need had made it possible for her to override her inbred fear and dislike of Reuben and beg him to help them. She had come, and since she had come it must not be in vain; the worst was over now that she was actually here, that she had actually pleaded. She would face it out.
  • 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:"Wot d'you want to go buying Boarzell fur?" asked Mrs. Backfield in a bewildered voice; "the farm's pr?aper as it iswe d?an't want it no bigger.""Never mind that. As for me, I am not quite foundered, although I have left a cargo behind at Winchcombe that would have bought a dozen bondmen's freedom. Come with me to London: I have part of a galley of my own there, and you may either stow away in some hole of the city, or slip your cable, and be off for Genoa, where I'll promise you as snug a birth as a man could wish for. Besides, there is your childis it a boy?"

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

THREE:"And your damned son!" furiously cried Ditch of Totease."Yesdidn't I tell you so this moment?" answered Bridget, rising somewhat indignantly, and replacing the flower-pot in its original position. "And trouble enough I have had," she continued, "to get in the table and the chairs, and the benches, and stools, and put the place so that it might be fit to be seen, all by myself. A fine holiday the wench has got!but she shall work for this next week!How many are coming?"
  • 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.
