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:Shorty, by watching the motions of the other's hand, was skillful enough to catch on to the grip this time, and get it exactly. He expressed himself satisfied, and as the car lay on the siding waiting for another train to arrive and pass he favored his two companions with one of his finest fictions about his home in Tennessee, his service in the rebel army, the number of Yankee Abolitionists he had slain with his own hand, and his present mission with important communications to those "friends of the South in Illinois" who were organizing a movement to stop the bloody and brutal war upon his beloved Southland.
  • 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:"Dr. Rogier has his preparations," the old woman said. "I'm sure they are as efficient as they can be. They are useless, but he knows that as well as I do."In every camp the cheering men were making bonfires of the furnishings of their Winter camps. Chairs, benches, tables, checker-boards, cupboards, what-nots, etc., which had cost them considerable pains to procure, and upon which they had lavished no little mechanical skill, and sometimes artistic ornamentation, were ruthlessly thrown to feed the joyful fires which blazed in each camp which had been lucky enough to receive orders. The bands were playing, to emphasize and give utterance to the rejoicings of the men.

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

THREE:"There's more than 3D tapes," the squat man said, and grinned.She shook her head, the smile remaining. Her voice was quiet and calm, but there was a feeling of strain in it: there was strain everywhere, now. Everyone looked at the sky, and saw nothing: everyone listened for the sound of engines, and there were no engines to hear. "Catalepsy is a kind of death, Johnny. And you'll have to inflict that much on yourself. You won't do 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.

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