TWO:THE Deacon reached the corn-crib again be fore daylight, and found Si and Shorty fast asleep. This relieved him much, for he had been disturbed with apprehensions of what might happen them while he was gone. Though he was more tired, it seemed to him, than he had ever been before in all his life, yet he nerved himself up to clean and cook one of the chickens, so as to give Si a delightful surprise when he awoke.

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:But the planet had natives on it already. The natives were called Alberts, and here is a picture of them. Aren't they funny-looking?"To tell you the truth," answered Shorty, "I was after them to enlist with us. We lost five men in the shuffle at Nashville, and I was lookin' out for some to take their places.
  • 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:While Si and Shorty were still worrying about what to do for arms for the remainder of their men, they heard what seemed to be about a company marching toward them through the darkness.

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

THREE:Similarly, the Sergeants stood behind their sections, except that one after another they stepped forward to the guns to take the places of men who had fallen and could not be replaced. At the guns the men were working with the swiftness of light flashes, and the unerring certainty of machines. To the watchers at the base of the slope they seemed to weave back and forth like some gigantic, demoniac loom, as they sprang at their guns, loaded them, "broke away" as they fired, leaped back again, caught the gun in its recoil, hurled it forward, again reloaded, "broke away" and fired, all quicker than thought. A shell took off a sponger's head, but the sponge-staff was caught by another before it fell, and the gun fired again without a pause. A shrapnel swept away every man about one gun. The Lieutenant looked inquiringly at the Sergeant, and in an instant another squad seemed to spring up from the ground to continue the firing without missing a note in the battery's rhythm.
  • 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:

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