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:With a yell the regiment swept across the clearing into the brush beyond. A furious, noisy scrambling ensued in the thickets. Neither side could see 10 yards ahead, and the firing, though fierce and rapid, was not very effective. Men shot at sounds, or motions of the bushes, and the bullets, glancing on the limbs, whistled in all directions. But the 200th Ind. pressed furiously forward, and though the rebels resisted stubbornly they were gradually pressed back up the hill. Occasionally one was killed, many were wounded, and squads were caught in clumps of brush and compelled to surrender. Si and Shorty kept their boys in hand, on the left of Co. Q, restrained them from firing until they saw something to shoot at, and saw that they did not advance until their guns were loaded. They heard a crashing volley delivered on their right front, and springing swiftly in that direction, came to a little break, across which they saw a squad of 15 or 16 rebels under the command of a Captain, with their guns still smoking, and peering into the woods to see the result of their fire. Si rushed at the Captain, with leveled gun, and ordered him to surrender.SI AND SHORTY TAKE CHARGE OF A SQUAD OF RECRUITS.
  • 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 got a big piece o' that new red Sunday dress o' her's," said Sammy, going to his storehouse and producing it. "I cribbed it once, to make me a flag or something, when I'd be out fightin' the Injuns. Will that do you?"

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

THREE:There was only one thing for him to do. He sat crosslegged on the smooth floor as the rumble and the other sounds continued, and in opposition to them he made his song, chanting in a loud and even voice. He had learned that a song was to be made when facing death: he had learned that in the birth huts, and he did not question 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:There was an alarm-bell, to be exact, an alarm-buzzer, combinations and solo cadenzas. The guards were, after all, no more than dressing: the automatic machinery never slept, and it responded beautifully and with enthusiasm."Are any o' them men you see over there guerrillas?" they asked.

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