TWO:Cairness put his arm around the big angular shoulders and helped her into the sitting room. She dropped down upon the sofa, and sat there, her head hanging, but in sullenness, not humility.

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:There was a stronger blow at the door, as of a log used by way of a ram. It gave, swayed, and fell crashing in, and the big room swarmed with screaming fiends, their eyes gleaming wildly in the light of the burning hay and the branches piled against the cabin, as they waved their arms over their feathered heads.The man on the ground twisted his body around on his crushed leg, pinned under the pony, aimed deliberately at the white figure, and fired. Felipa's firm hold upon her revolver turned to a clutch, and her mouth fell open in a sharp gasp. But very deliberately she put the revolver into its holster, and then she laid her hand against her side. At once the palm was warm with blood.
  • 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:He raised himself from the pillows too abruptly for a very weak man. "What is the matter, Felipa?" he demanded.

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

THREE:"I am far from being sure that that is entirely to be desired, very far," said Cairness, with conviction. He had never ceased to feel a certain annoyance at[Pg 319] the memory of that year and a half of Felipa's life in which he had had no part.
  • 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:Stone thought not. He had not heard Lawton speak of needing help. But he wrote a very guarded note of recommendation, falling back into the editorial habit, and dashing it off under pressure. Cairness, whose own writing was tiny and clear and black, and who covered whole sheets without apparent labor, but with lightning rapidity, watched and reflected that he spent an amount of time on the flourish of his signature that might have been employed to advantage in the attainment of legibility.

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