TWO:"I don't know what has been said, Major, but something more than just what's in the papers must have gotten about. That sort of mud-slinging is too common to cause comment, even. It must be some spite work. There's no reason to suppose, surely, that after a quarter of a century of gallant service he's been and shown the white feather. He's awfully cut up, really he is. He's noticed it, of course, and it's too deuced bad, kicking a man when he's down sick and can't help himself."

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:Forbes shrugged his shoulders. "You'll pardon me if I say that here she is a luxurious semi-barbarian." It was on his tongue's tip to add, "and this afternoon, by the spring-house, she was nearly an Apache," but he checked it. "It's very picturesque and poetical and all that,—from the romantic point of view it's perfect,—but it isn't feasible. You can't live on honeycomb for more than a month or twain. I can't imagine a greater misfortune than for you two to grow contented here, and that's what you'll do. It will be a criminal waste of good material."
  • 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:"Yes," Cairness called back."I shall be in and out all night, more or less," he told Felipa. She reached her hands from the bedclothes and stroked the deep lines on his forehead, the lines she had had most to do with putting there. But she did not ask for confidences. She never did. It was not her way. He kissed her and went out into the night again, to sit upon his porch at a spot where, through the cottonwood branches, he commanded a view of Brewster's front door and of the windows of the commissary office.

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

THREE:
  • 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:Mrs. Ellton returned before long, and Landor went back home.
