TWO:Night suddenly came, with pitchy darkness, but Si steadily forged onward. Then the rain ceased as suddenly as it began, but the road was encumbered with fallen timber and swirling races of muddy water. They seemed more uncomfortable even than when the rain was falling. They were now nearing the mill, and the sound of a fitful musketry fire came to their ears.

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:"Let me see, Steigermeyer," said the Major, adjusting another chew of tobacco to his mouth, and balancing the knife with which he had cut it off, judicially in his fingers, a favorite position of his when, as a lawyer, he was putting a witness through a cross-examination. "How long have you been with this army? Came West with the Eleventh Corps, didn't you?"
  • 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:"I've come down here to do all that's possible for these two boys. Now, how kin I best do it?" asked the Deacon.

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

THREE:The rebels listened with growing impatience to the words, and as Monty concluded with his best flourish they yelled angrily:Si returned dejectedly to the place where he had left his squad. The expression of his face told the news before he had spoken a word. It was now getting dark, and he and Shorty decided that it was the best thing to go into bivouac where they were and wait till morning before attempting to penetrate the maze beyond in search of their regiment. They gathered up some wood, built fires, made coffee and ate the remainder of their rations. They were all horribly depressed by little Pete Skidmore's fate, and Si and Shorty, accustomed as they were to violent deaths, could not free themselves from responsibility however much they tried to reason it out as an unavoidable accident. They could not talk to one another, but each wrapped himself up in his blanket and sat moodily, a little distance from the fires, chewing the cud of bitter fancies. Neither could bear the thought of reporting to their regiment that they had been unable to take care of the smallest boy in their squad. Si's mind went back to Peter Skidmore's home, and his mother, whose heart would break over the news.
  • 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 felt hopeless and dragged-out and like something you'd never want to go through again, am I right?"SI," said the Orderly-Sergeant, "here's a chance to give them pin-feather roosters o' yours a little taste of active service, that'll be good seasoning for 'em, and help develop their hackles and spurs."

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