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:"Aye," said Calverley, with a smileif the curve of a bloodless lip could be so designated"aye, you name her rightly, Byles: she is a fox, and like a fox shall she die,hunteddriventortured. Byles, have you never heard it said that this woman was a witch?"
  • 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:The hall had a tesselated pavement, on which the arms of the united families of Sudley and De Boteler (the latter having inherited by marriage, in consequence of a failure of male issue in the former) were depicted with singular accuracy and beauty. About midway from the entrance, two broad steps of white marble led to the part of the hall exclusively appropriated to the owner of the castle. The mosaic work of this privileged space was concealed on the present occasion by a covering of fine crimson cloth. A large arm chair, covered with crimson velvet, with the De Boteler arms richly emblazoned on the high back, over which hung a velvet canopy fringed with gold, was placed in the centre of the elevation; and several other chairs with similar coverings and emblazonings, but wanting canopies, were disposed around for the accommodation of the guests.And turn to your true loveand find it too late."

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

THREE:
  • 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:The yeoman re-entered, and Sir Robert began, in a voice so familiar, that Byles was thrown off his guard. "John Byles, how came you to be so foolish as to fall in the ravine the night you and Sam went to shoot the buck?""Margaret," said John, "your silence does but confirm my suspicions. It is a cruel revengebut it is doneand Stephen's life shall never be put in jeopardy by a breath of mine. He has suffered, but till now he had not sinned! But his sin be between his conscience and his God:" he paused for a minute, and then looking tenderly upon his sister, he said as gently as he could, "Farewell!" and being anxious to avoid an interview with Holgrave, abruptly departed.
