TWO:"How's things up at Grant?" he drawled through his beard, as he took off that sacred and ceremonious garment known to the true frontiersman as his vest, and without which he feels as lost as without his high-heeled boots.

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:And so the hostiles took shelter there from the cavalry that had pursued them hard across the open all night, and gave battle after the manner of their kind. It was a very desultory sort of a skirmish, for the troops did not venture into the traps beyond the very edge, and the Indians were simply on the defensive. It was not only desultory, it promised to be unavailing, a waste of time and of ammunition.
  • 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:"Say!" she apostrophized.

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

THREE:But the Apaches held it for only a day, for all that. They were unprepared and overconfident. Their bucks were for the most part away plundering the hapless Mexican settlements in the desert below. They had thought that no white troops nor Mexicans could follow here, and they had neglected to count with the scouts, who had been hostiles themselves in their day, and who had the thief's advantage in catching a thief. And so while the bucks and children wandered round among the trees or bathed in the creek, while the hobbled[Pg 230] ponies grazed leisurely on the rank grass, and the squaws carried fuel and built fires and began their day of drudgery, they were surprised.
  • 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:The next two days he kept to himself and talked only to his Apache scouts, in a defiant return to his admiration for the savage character. A Chiricahua asked no questions and made no conventional reproaches at any rate. He was not penitent, he was not even ashamed, and he would not play at being either. But he was hurt, this last time most of all, and it made him ugly. He had always felt as if he were of the army, although not in it, not by reason of his one enlistment, but by reason of the footing upon which the officers had always received him up to the present time. But now he was an outcast. He faced[Pg 302] the fact, and it was a very unpleasant one. It was almost as though he had been court-martialled and cashiered. He had thoughts of throwing up the whole thing and going back to Felipa, but he hated to seem to run away. It would be better to stop there and face it out, and accept the position that was allowed him, the same, after all, as that of the majority of chiefs of scouts.
