TWO:Marvor closed his eye and made the hissing sound again; it was equivalent to a laugh of rejection. He turned among the leaves and found enough room to lie down: in a few seconds he was either asleep or imitating sleep very well. Cadnan looked at him hopefully, and then turned away. A female was watching him from the other side, her eyes wide and unblinking.

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:The wearied men went stumbling along the rough road for what seemed the longest mile ever known. It had grown very dark. At last a form separated itself from the bank of blackness on the left, and a voice said in a penetrating whisper:The eager boys had already begun firing, entering into the spirit of the thing with the zest of a Fame of town-ball. Shorty took Gid Mackall and Harry Joslyn down to the cover of some large stones, behind which they could lie and command the approach to the other end of the bridge with their rifles. Si took the other boys and placed them behind rocks and stumps along the crest and instructed them to fire with as good aim as possible at the flashes from the other side. In a minute or two he had a fine skirmish-line in operation, with the boys firing as deliberately and accurately as veterans. The engineer had backed the train under the cover of the cut, and presently he and the conductor came up with guns and joined the firing-line.
  • 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:With a shock he realized that "everyone" included Dara.

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

THREE:But one after another found this tiresome after awhile and set himself to his usual camp employments and diversions. Some got out needles and thread, and began repairing their clothes. Some gathered in groups and smoked and talked. Many produced the eternal cards, folded up a blanket for a table, and resumed their endless sevenup and euchre or poker for buttons and grains of corn. Jim Humphreys found his way into one of these games, which was played behind a clump of bushes, and the buttons represented dimes. He was accumulating fractional currency. Gid Mackall embraced the opportunity to cook for himself a savory stew with some onions distributed by the Sanitary Commission. Sandy Baker went over his gun, saw that every screw was properly tight, and dropped the tiniest amount of oil on the trigger and the hammer, to ease their working. Pete Skidmore wandered down to the flank of the next regiment to find out if anything new had occurred. Harry Joslyn got himself into the exact "position of a soldier," with his heels together, his toes pointed at an angle of 45 degrees, and went through the manual of the piece endlessly. Si and the Orderly-Sergeant communed together about the rations for the company, and the various troubles there was always on the Orderly's mind about the company's management. Shorty got off by himself, produced from his breast his mementoes of Maria, and read over her last letter for the thousandth time, though he knew every word in it. But he seemed to get a new and deeper meaning every time he read it.
  • 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).
