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:"O, he was an ornament to the army," continued the unblushing Shorty, who hadn't had a good opportunity to lie in all the weeks that the Deacon had been with him, and wanted to exercise his old talent, to see whether he had lost it. "And the handsomest man! There wasn't a finer-looking man in the whole army. The Colonel used to get awfully jealous o' him, because everybody that'd come into camp 'd mistake him for the Colonel. He'd 'a' bin Colonel, too, if he'd only lived. But the poor fellow broke his heart. He fell in love with a girl somewhere up NorthPewter Hatchet, or some place like that. I never saw her, and don't know nothin' about her, but I heard that the boys from her place said that she was no match for him. She was only plain, ordinary-lookin'."
  • 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:"Confound it," said Si savagely; "you talk about runnin' over men as if it was part o' your business."

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

THREE:Feeling entirely at ease, he climbed into the car, with a copy of the Cincinnati Gazette, which he had bought of a newsboy, lighted his pipe, put on his spectacles, and settled down to a labored, but thorough perusal of the paper, beginning at the head-lines on the upper left-hand corner, and taking in every word, advertisements and all, as systematically as he would weed a garden-bed or milk a cow. The Deacon never did anything slip-shod, especially when he had to pay 10 cents for a copy of the Cincinnati Gazette. He was going to get his full money's worth, and if it was not in the news and editorials, he would take it out of the advertisements and patent medicine testimonials. He was just going through a convincing testimonial to the manifold virtues of Spalding's Prepared Glue, when there was a bump, the sound of coupling, and his car began to move off."Doesn't matter," Dodd told him. "I can understand how you feel. We've treated youpretty badly, I guess. Pretty badly." He looked away with what seemed nervousness. But there was nothing to see outside the door, nothing but the corridor light that spilled in and framed him.
  • 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 Captain dropped his sword, and his men yielded."Harry Joslyn 's runnin' nose-and-nose with him. There ain't the width o' their forelocks difference. Harry's yelled for more beans at the same second that Gid has. In fact, not one of 'em has lagged. They're a great gang, I tell you, but I wouldn't want to board any one of 'em for six bits a week."
