TWO:"I beg your pardon, madam," he said. "It happens to be my business, though."Felipa felt something of this, and it lessened the vague burden of self-reproach she had been carrying. She was almost cheerful when she got back to the post. Through the last breakfast, which the Elltons took for granted must be a sad one, and conscientiously did their best to make so, she had some difficulty in keeping down to their depression.

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:He nodded forcibly. "Where all them mesquites is to one side, and the arroyo to the other. They'll be behind the mesquite. But you ain't goin' to head him off," he added, "there ain't even a short cut. The road's the shortest."Cairness started forward and levelled his Colt, but the divine was too quick for him. He fired, and the cow-boy sank down, struggling, shot through the thigh. As he crouched, writhing, on the ground, he fired again, but Cairness kicked the pistol out of his hand, and the bullet, deflected, went crashing in among the bottles.
  • 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:She stood alone, with the sticky, wet knife in her hand, catching her breath, coming out of the madness. Then she stooped, and pushing the branches aside felt about for her pistol. It lay at the root of a tree, and[Pg 80] when she had picked it up and put it back in the holster, there occurred to her for the first time the thought that the shot in the dead stillness must have roused the camp. And now she was sincerely frightened. If she were found here, it would be more than disagreeable for Landor. They must not find her. She started at a swift, long-limbed run, making a wide detour, to avoid the sentries, bending low, and flying silently among the bushes and across the shadowy sands.

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:The general turned his head sharply, and his eyes flashed, but he only asked dryly, "Why?"But he kept a close watch upon her then and during all the hard, tedious march back to the States, when the troops and the scouts had to drag their steps to meet the strength of the women and children; when the rations gave out because there were some four hundred Indians to be provided for, when the command ate mescal root, digging it up from the ground and baking it; and when the presence of a horde of filthy savages made the White-man suffer many things not to be put in print.

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