TWO:Stone did not understand. He believed that he missed Mr. Cairness's meaning. "I don't think you do," said Cairness; "but I'll make it plainer, anyway. I want you to get out of the country, for the country's good, you know, and for your own. And I give you[Pg 259] three days to do it in, because I don't wish to hurry you to an inconvenient extent."

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:Ellton himself answered the muffled knock. "I didn't turn in," he said to the mysterious figure, shrouded in a cape, with a visor down to its peering eyes.
  • 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:But in the days of Victorio and his predecessors and successors, Aravaypa Ca?on was a fastness. Men went in to hunt for gold, and sometimes they came out alive, and sometimes they did not. Occasionally Apaches met their end there as well.

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

THREE:He found that it had been father and son come from the Eastern states in search of the wealth that lay in that vague and prosperous, if uneasy, region anywhere west of the Missouri. And among the papers was a letter addressed to Felipa. Landor held it in the flat[Pg 146] of his hand and frowned, perplexed. He knew that it was Cairness's writing. More than once on this last scout he had noticed its peculiarities. They were unmistakable. Why was Cairness writing to Felipa? And why had he not used the mails? The old, never yet justified, distrusts sprang broad awake. But yet he was not the man to brood over them. He remembered immediately that Felipa had never lied to him. And she would not now. So he took the stained letter and went to find her."Have I ever lied to you?" Crook asked them.
  • 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:Landor sent for a squad of the guard and went to put them out. It was just one of the small emergencies that go to make up the chances of peace. He might or he might not come back alive; the probabilities in favor of the former, to be sure. But the risks are[Pg 186] about equal whether one fights Indians or citizens drunk with liquor and gaming.

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
