TWO:Unfortunately it was also more difficult to get. Those years had been bad for everybody, and none of the surrounding farmers seemed disposed to add to his burdens by so uncertain a deal. If the thing had not[Pg 289] thriven with Backfield it was not likely to thrive with anyone else. For the first time Reuben cursed his own renown.

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:"It becomes the bondman to speak thus of his lord," said Calverley with a sneer.Moreover, she still sometimes had a vague feeling that at the start Harry had not been quite so mad as people thought, that he might perhaps have recovered if she had made him understand that she was true to him, still hoping. No doubt that was all nonsense, but she could not quite smother the idea that she had betrayed Harry. Perhaps it was partly because even before his accident she had cast longing eyes at Reuben. Once again she called up memories of him cutting down willows on his new land, and she acknowledged miserably to herself that in that hour she had already been unfaithful to Harry in her heart, and that all that came afterwards was but the following up of that initial act of treachery. A strong arm, a broad back, a blue shirt in the January twilight ... and Naomi had set out[Pg 105] on a road every step of which was now over rough stones and broken shards.

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

THREE:Father John gazed upon her with a look of compassion; and, though aware of the danger he should incur, he said, after a short struggle:Hitherto he had always considered the opposite of his ambition to be the absence of it. Either one lived to subdue the hostile earth, or one lived with no object at all. It was a new experience to find someone whose life was full of hopes, ideals, and ambitions, all utterly[Pg 217] unconnected with a farm, and it was even more strange than new that he should care to talk about them. Not that he ever found himself being tempted from his ownthe most vital part of his relations with Alice Jury lay in their warfare. He fought her as he fought Boarzell, though without that sense of a waiting treachery which tinctured his battles with the Moor; their intercourse was full of conflict, of fiery, sacred hostilities. They travelled on different roads, and knew that they could never walk together, yet each wanted to count the other's milestones.
  • 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.
