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:A great many delightful facts, illustrative of the rule of the Anglo-Saxon in for gain, came to his knowledge. There were good men and just in Arizona, and some of these composed the Federal Grand Jury, which reported on the condition of affairs at the Agency. When a territorial citizen had anything to say in favor of the Redskin, it might be accepted as true. And these jurymen said that the happenings on the San Carlos Agency had been a disgrace to the age and a foul blot upon the national escutcheon. They waxed very wroth and scathing as they dwelt upon how the[Pg 177] agent's vast power made almost any crime possible. There was no check upon his conduct, nor upon the wealth he could steal from a blind government; and to him, and such as him, they attributed the desolation and bloodshed which had dotted the plains with the graves of murdered victims. It was the rather unavailing wail of the honest citizen caught between the upper and nether millstones of the politician and the hostile.
  • 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:

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

THREE:If it went like this, she thought, she might get to the cross-road first, and beyond. The four men would not matter much then, if she could but stop her husband. Why had he started back alone—and carrying money too? It was foolhardy. But then there was so little money, she knew, that he had probably not thought of it as booty. She turned her uncovered head and listened. Her hair had fallen loose and was streaming out in the wind. She could not hear the others now. They must be well behind.He knew while he was yet afar off which was the American. She stood, big and gaunt, with her feet planted wide and her fists on her hips, looking over toward the general's tent. And when Cairness came nearer, strolling along with his hands in his pockets, observing the beauties of Nature and the entire vileness of man, she turned her head and gave him a defiant stare. He took his hands from his pockets and went forward, raising his disreputable campaign hat. "Good morning, Mrs. Lawton," he said, not that he quite lived up to the excellent standard of Miss Winstanley, but that he understood the compelling force of civility, not to say the bewilderment. If you turn its bright light full in the face of one whose eyes are accustomed to the obscurity wherein walk the underbred, your chances for dazzling him until he shall fall into any pit you may have dug in his pathway are excellent.
  • 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:"Yes, sir," he answered; "you can see that I get a mounted man and a horse at reveille to-morrow. I want to hunt for my pony. I lost it when I caught that man."

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