TWO:The fields were very dark in their low corners, only their high sweeps shimmered in the ghostly lemon glow. Out of the rabbit-warrens along the hedges, from the rims of the woods, ran the rabbits to scuttle and play. Bessie and Robert saw the bob of their white tails through the dusk, and now and then a little long-eared shape."You talk strange language," replied Calverley in a voice that had lost all its assumed gentleness. "ButrememberI have not sought your sister's love to be thus baffledremember!--" Calverley was here interrupted by a quick knocking at the door.

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:Caro ran out once or twice into the garden; the flowers hung pale and stirless on their stems, and from the orchard, full of the babble of a hidden wind, came a faint scent of plums. The old walls of Odiam seemed to smell of the sunshine they had caught and held during the day. The gable-ends broke into the stars, and the windows gleamed in the yellowing light of the moon. Up towards the south the mass of Boarzell rose hullish and desertedfar away at Ellenwhorne a dog was barking, but all else was still.
  • 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:Rose was intensely relieved. She felt that at last and for ever the tormenting mystery would have gone from her life. Once Handshut was away, she told herself, she would slip back into the old groovea little soberer and softer perhaps, but definitely free of that Reality which had been so terribly different from its toy-counterfeit.

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

THREE:That autumn David and William went to Newhaven to see the Rye Football Club play the West Sussex United. They had more than once gone on such jaunts together, and on this occasion, trains being difficult, they put up for the night at a small hotel near the port. It was the first time they had spent a night away from Odiam, and a certain thrill attached to it.
  • 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:

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