TWO:She sat considering deeply. She was rocking the baby, with its little fair head lying in the hollow of her shoulder, and Landor found himself wondering whether Felipa could ever develop motherliness. "It is quite intangible," Mrs. Campbell half crooned, for the baby's lids were drooping heavily. "I can't find that she lacks a good characteristic. I study her all the time. Perhaps the fault is in ourselves, as much as anything, because we insist upon studying her as a problem, instead of simply a very young girl. She is absolutely truthful,unless she happens to have a grudge against some one, and then she lies without any scruple at all,and she is generous and unselfish, and very amiable with the children, too."

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:[121]
  • 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:If the stick was jammed, it might be possible to get into the fuselage. There he might operate the elevator cable by hand enough to get that nose up more, flatten the glide, maybe enough to enable Larry, who alone had a stick, to swing around and come down on landsomehow.

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

THREE:There was only Mrs. Campbell who knew the whole story. Landor had gone to her for advice, as had been his custom since the days before she had preferred Campbell to him. "Felipa," he said, "writes that she is going to run away from school, if I don't take her away. She says she will, and she undoubtedly means it. I have always noticed that there is no indecision in her character."
  • 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:It was called! the detective showed a baffled face.
