TWO:But after the gun was gone, and after Shorty had written a laborious letter, informing Sammy of the shipment of the gun and its history, which letter inclosed a crisp greenback, and was almost as urgent in injunctions to Sammy to write as Sammy had been about his piece of ordnance, Shorty sat down in sadness of heart. He was famishing for information from Maria, and at the lowest calculation he could not hope for a letter from Sammy for two weeks.

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:"Sich ignorance," groaned Si. "Can't they read? Don't they git the papers?"
  • 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:"No," said Si, who was irritated by his partner's irreverence: "but it's the way a good soldier does. His first dooty's to take care o' his grub, because that's takin' care o' himself, and keepin' himself in good shape to do the dooty the Government expects o' him. 'Tain't servin' the Government right for him to be careless about himself. Now here's 27 rations o' bread, meat, coffee, sugar, salt and beansthree apiece for each of us. Harry Joslyn, you and Gid Mack divide them up into nine equal piles."

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

THREE:"All right. Take Co. A. Push them as far as you can, for the orders are to develop their strength at once. I'll follow close behind and help you develop, if you need me."
  • 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:"No," the boys assured him. "They broke up camp completely. All that wasn't able to march was sent to the hospital in Chattynoogy. Every mite of stuff was loaded into wagons and hauled off with 'em. They never expected to come back."
