TWO:The remainder of the drive Cairness devoted to caring for the broken wing of the hawk, and, during halts, to sketching anything that presented itself,—the mules, the driver, passing Mexicans, or the cows trying to graze from ground where the alkali formed patches of white scum. He also accomplished a fine caricature of the lieutenant, and derived considerable silent amusement therefrom.

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:"Why?" she asked, with a quick suspicion of the dreariness she caught in his tone.And the next day she knew. When she came out in front of her quarters in the morning, rather later than usual, there was a new tent beside the hospital,[Pg 81] and when she asked the reason for it, they told her that a wounded Apache had been found down by the river soon after the shot had been fired the night before. He was badly hurt, with a ball in his shoulder, and he was half drunk with tizwin, as well as being cut in a dozen 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:The sergeant spent more time upon the oaths with which he embellished the counter-question as to how he should know anything about it, than would have been consumed in a civil explanation.It gave cause for reflection; but an officer was obviously at liberty to talk to whomsoever he might choose around his own premises, at any hour of the day or night. So the officer of the day went on, treading quietly. But he had something to think about now that kept off drowsiness for the rest of the rounds. Brewster's fondness for the society of dubious civilians was certainly unfortunate. And the conjunction of the aspiring beef contractor and the commissary officer was also unfortunate, not to say curious. Because of this. The beef contract was about to expire, and the commandant had advertised for bids. A number of ranchers had already turned their papers in. Furnishing the government's soldiers with meat is never an empty honor.

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

THREE:When, therefore, Mrs. Landor said, with the utmost composure, that it was too bad, his gasp was audible.There fell a moment's pause. And it was broken by the sound of clashing as of many cymbals, the clatter of hoofs, the rattle of bouncing wheels, and around the corner of the line there came tearing a wagon loaded with milk tins. A wild-eyed man, hatless, with his hair on end, lashed his ponies furiously and drew up all of a heap, in front of the commanding officer's quarters.
  • 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.

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