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:"Why, my lord," answered Turner, with composure, "I told you before that if I knew where Holgrave was, I would not tell."So no constable called at Odiam the next morning, and at breakfast the whole Backfield family discussed the Squire's loss, with the general tag of "serve him right!"
  • 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:She thought it over for two months, during which Reuben suffered all the torments of his lot. She soon came to realise and appreciate her powers; she dangled hopes and fears with equal zest before his eyes, she used his anxieties to stoke the furnaces of his passion, till she had betrayed him into blazes and explosions which he looked on afterwards with uneasy shame."Why? Since your husband can't go, wot's more likely than he shud send his man to t?ake you?"

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

THREE:She picked the child out of the cradle, and began to walk up and down the room, rocking it in her arms. Fanny's wails grew louder, more long-drawn, and more plaintive.
  • 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:"Only that he walks home wud them from church every Sunday, and f?alkses are beginning to wonder which he's going to m?ake Mrs. Realf, surelye!"
