TWO:The Doctor stabbed a finger wildly in the direction of the coal cellar. "If you had seen what I have seen to-night, you would understand. You would be feeling exactly as I am now."Well, go on; but take care, he said.

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:"Are you going to count them?" It seemed so much easier to let them count us.

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

THREE:It isnt only his attendance there that I mean,{104} said Mr Silverdale. But you know his Stores are in my parish, and he employs some four hundred work-people there. I went to see him at his office this morning, and asked him if I couldnt have a daily service for them.
  • 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:She had watched him come down the path, and when he was some ten paces from her, she rose. She had no word, it would seem, for him, nor he for her, and they stood in silence opposite{312} each other. But the clear glance shone on him, steady and quiet and complete. Then, as by some common impulse, her hands and his were clasped together.She paused in her work but did not look at him.
