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:
  • 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:Robert bit off the end of his pencil, which his father,[Pg 160] who was looking the other way, luckily did not see. The boy crouched over the fire, trying to hide his trembling, and longing yet not daring to ask a hundred questions. He was glad and at the same time sorry when Reuben having explained to him the right and the wrong way of sowing beans, and enlarged on the wickedness of Radicals in general and Gladstone in particular, returned to Bardon's loss."Good-bye, my Bluebell, farewell to you,

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

THREE:In the kitchen a substantial meal was prepared. It was the children's supper, and was to last Reuben till he came in at nine o'clock and had a bowl of broth before going to bed. Old Mrs. Backfield was settling the children round the table. Caro and Tilly showed only their heads above the cloth, a piece of neck proclaimed Benjamin's extra inches, while Richard had quite two buttons to his credit. Harry sat at the bottom beside Caroline; when he heard Albert's rattle, he seized it and began making a hideous din. Caro and Tilly began to cry, and Reuben snatched the rattle away.
  • 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.
