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:Turner had not been above five minutes in releasing the monk; but, when he came to the entrance of the keep, Merritt and the remainder of the band were sharply engaged with the domestics and the few tenants who kept guard about the castle. The smith pushed on with the monk; passed Merritt and the others, who closed in his rear; and, with that boldness, which often effects what more prudent courage would fail to accomplish, rushed into the midst of the assailants, brandishing his weapons, and shouting defiance at the top of his stentorian lungs.
  • 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:Caro flushed with pleasurea light had kindled in her grey life, and she found herself looking forward to days of basking."Praise be to God that his life was spared."

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

THREE:The barred gates of the Fleet prison flew open before the assailants, and the wretched inmates felt their feverish temples once more cooled by the pure breath of liberty. At about a hundred paces from the Fleet, they passed a house, having the bush suspended in front, indicating its possessor to be a vintner; and the host himself, with singular foolhardiness, stood looking out from the open casement of the first story.
  • 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:After the dance, which did not last long, as poor Robert trod so heavily on his partner's feet that she soon begged him to stop, they strolled off round the Fair. Robert thought that if he made it a custom to roam among the booths his father would not notice his final disappearance so quickly. Lord! he was getting a hemmed crafty fellow. All the boys were allowed a shilling or two to spend at the Fair, so Robert treated Emily to a ride on the merry-go-round and five sea-sick minutes in the swings. Then he took Mrs. ButtonRealf's married daughter, who had come over from Hove, to see the Panorama and a new attraction in the shape of a fat lady, which struck him as disgusting, but made her laugh tremendously.
