TWO:And Brewster said he had not.

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:"We'll see," she answered shortly; "it is where the Huachuca road crosses, you are certain?"The Indians, being wicked, ungrateful, suspicious characters, doubted the promises of the White-eyes. But it is only just to be charitable toward their ignorance. They were children of the wilderness and of the desert places, walking in darkness. Had the lights of the benefits of civilization ever shone in upon them, they would have realized that the government[Pg 226] of these United States, down to its very least official representative, never lies, never even evades.
  • 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 was a splendid spring morning. There had been a shower overnight, and the whole mountain world was aglitter. The dancing, rustling leaves of the cottonwoods gleamed, the sparse grass of the parade ground was shining like tiny bayonets, the flag threw out its bright stripes to the breeze, and when the sun rays struck the visor of some forage cap, they glinted off as though it had been a mirror. All the post chickens were cackling and singing their droning monotonous song of contentment, the tiny ones cheeped and twittered, and in among the vines of the porch Felipa's mocking-bird whistled exultantly.They had been doing that for three days. They came down the chimney, made across the floor in a line that never changed direction, nor straggled, nor lessened, up the wall and out a crack in the window. They did no harm, but followed blindly on in the path the first one had taken. And the minister had said they should not be smoked back or thwarted.

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

THREE:He realized for the first time the injury his thought of it did her. It was that which had kept them apart, no doubt, and the sympathy of lawlessness that had drawn her and Cairness together. Yet he had just begun to flatter himself that he was eradicating the savage. She had been gratifyingly like other women since his return. But it was as Brewster had said, after all,—the Apache strain was abhorrent to him as the venom of a snake. Yet he was fond of Felipa, too.
  • 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 herself lay at full length upon a couch she had devised out of packing cases. It occurred to Landor that she often dropped down to rest now, and that she was sallow and uneasy.
