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:Johns eye, which had exactly as much expression in it as a dead codfishs, cowed him for a moment, but he quickly recovered.A GENTLEMAN OF CHIN-KIANG. A GENTLEMAN OF CHIN-KIANG.
  • 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:Of course. I am consulting you.His voice died away. The Curate was not actually shaking his head, but there was upon his features an expression of incredulity, the like of which the Doctor had not seen before upon a human face, for it was the incredulity of a man to whom all arguments against the incredible are in themselves unbelievable. It was a grotesque expression, and with it there went a pathetic fluttering of the Curate's eyelids, a twitching of his lips, a clasping of small white hands.

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

THREE:"Yes, General, if I don't have to save the horse.""HeHehadn't got no back to his head," blurted out Tom at last.
  • 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:I was waiting till you had finished, Mamma! she permitted herself to observe.The Chinese cart is too short for an average-sized person to lie in at full length, and too low to allow him to sit erect; it has a small window on each side, so placed that it is next to impossible to look out and see what there is along the route. Altogether it is a most uncomfortable vehicle to travel in, and the boys thought they would go on foot rather than ride in one of them.

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