TWO:"Well, it would never have done if the old man had got to know of it. Good heavens, Tilly! How can you live on with that old brute?"

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:But somehow found the subject more difficult to grapple than the fascinations of Amelia.
  • 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 aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.

THREE:Nothing of moment occurred at Sudley Castle for many months, if we except the birth of an heir; the appointment of Mary Byles, through Calverley's influence, to be the nurse; and the accession of Calverley himself to the coveted stewardship. The baroness's infant grew a fine, healthy child; but, as is sometimes the case with stout children, it had occasionally convulsive fits in teething. This, however, was carefully concealed from the mother, and Mary continued to receive great praise for her nursing. But it unfortunately happened, that one morning, when the boy had been laughing and playing in the highest spirits, Mary saw its countenance suddenly change. This was the more unfortunate, as De Boteler and his lady were momentarily expected to return, after a fortnight's absence, and Mary had dressed the infant in its gayest apparel to meet its parents, and had been congratulating herself upon the sprightliness and health of the boy. No excuses of sleep would satisfy the mother now: if the child was not taken to her, the nurse was assured she would come to look at him, and kiss him as he slept.
  • 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:"Are they spirits?" asked the stranger in a subdued and terrified tone.

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