TWO:"Geronimo," mumbled the Apache, "has prayed to the Dawn and the Darkness and the Sun and the Sky to help him put a stop to those bad stories that people put in the papers about him. He is afraid it will be done as they say." The press of the country was full just then, and had been for some time past, of suggestions that the only good use the much-feared Geronimo could be put to would be hanging, the which he no doubt richly deserved. But if every one in the territories who deserved hanging had been given his dues, the land would have been dotted with blasted trees.And in all that time, his ground crewgot nowhere!

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:Id like to find out how the ghost gets in and out again, he reflected.They had been four days camping on Black River, a mountain stream rushing between the steep hills, with the roar of a Niagara, hunting deer and small game, fishing with indifferent success,to the disgust of the Apaches, who would much rather have eaten worms than fish,and entertaining visitors. There were any[Pg 90] number of these. One party had come out from Fort Apache, another from a camp of troops on the New Mexico road, and some civilians from Boston, who were in search of a favorable route for a projected railway.
  • 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:More deliberately, settling down, first the hanging bulk of the unknown man, then the spreading folds of the parachute drifted into mistand mystery.That very day the doubt had attained the proportions of a certainty. The sight of a Circle K cow had called up the subject of the massacre, and a cow-boy had said, "Them are the property of Bill Lawton, I reckon."

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

  • 2Solvent recovery and the refinement Solvent recovery and the refinement such as chemical industry, an industry of medical supplies, food industry, the fermentation industry.
