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:Landor did not stop to consider it. It was one of the few impulses of his life, or perhaps only the quickest thinking he had ever done. Cairness was there among the rocks, disabled and in momentary danger of his life. If it had been a soldier, under the same circumstances, Landor might have gone on and have sent another soldier to help him. It was only a chief of scouts, but it was a man of his own kind, for all that—and it was his enemy. Instinct dismounted him before reason had time to warn him that the affair of an officer is not to succor his inferiors in the thick of the fighting when there are others who can be better spared to do it. He threw his reins over his horse's head and into the hands of the orderly-trumpeter, and jumped down beside Cairness.
  • 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:"Then they all have 'medicine' on," Cairness continued, "redbird and woodpecker feathers, in buckskin bags, or quail heads, or prairie-dog claws. One fellow was making an ornament out of an adobe dollar. Every buck and boy in the band has a couple of cartridge belts and any quantity of ammunition, likewise new shirts and zarapes. They have fitted themselves out one way or another since Crawford got at them in January. I don't think there are any of them particularly anxious to come in."When the storm had fairly passed, they found Felipa's gray lodged in the root of a tree some distance down the creek; in no way hurt, oddly enough, but trembling and badly frightened. The saddle, even, was uninjured, though the pigskin was water-soaked and slippery.

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

THREE:About an hour after midnight there came thundering through the quiet of the night the sound of galloping hoofs along the road at the foot of the ravine. Cairness, lying broad awake, was the first to hear it. He sprang up and ran to the opening of the tent. He guessed that it was a courier even before the gallop changed to a trot, and a voice called from the invisible depths below, "Captain Landor?" with a rising intonation of uncertainty.Landor told him to get his cap and come out. He followed the shadows of the trees near the low commissary building, and they stood there, each behind a thick cottonwood trunk. Landor watched the light in Brewster's window. It disappeared before long, and they held their breaths. Ellton began to guess what was expected to happen. Yet Brewster himself did not come out.
  • 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:It was plain, even to Felipa, how thoroughly he enjoyed being with one who could talk of the past and of the present, from his own point of view. His Coventry had been almost complete since the day that the entire army, impersonated in Crook, had turned disapproving eyes upon him once, and had then looked away from him for good and all. It had been too bitter[Pg 310] a humiliation for him ever to subject himself to the chance of it again.She laughed too, musically, with a bewitching gurgle,[Pg 238] and gave him a swift glance, at once soft and sad. "Ella es muy fea, no es simpatica, la Gringa."
