TWO:Dara turned on him a face that seemed completely calm. "They do not see us," she said flatly. "Now do not speak."

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:It seemed an age until the whistle of the locomotive was heard. The engine had to stop to take water at the creek, several hundred yards from the station, and Maria's impatience to see Si and be the first to speak to him could not brook the delay.
  • 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:His cheek paled for an instant as the thought obtruded that the man might resist and he have to really shoot him."No he ain't," said Pete Skidmore, whose vanity was touched as well as his cupidity aroused. "Mind your own business, Mister Elliott. You're only a Corpril anyway. You hain't nothin' to do with me outside the company. I kin take care o' myself. I've beat these men twice, and kin do it again."

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

THREE:"Now, great Scott, what's up?" said Si angrily, as he quickly surveyed the surrounding country. He saw that they were not attacked, and then clambered to the top of the car, where he noticed little wreaths of powder-smoke lingering around the squad in which were Jim Humphreys, little Pete Skidmore and Wes. Brown.
  • 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:"Well, what's that got to do with your havin' a good breakfast?" said the newcomer plausibly. "You need that right off. Then we kin talk about your regiment. As a matter of fact, you're only enlisted in the Army of the United States and have the right to go to any regiment you please. Tyrannical as the officers may be, they can't take that privilege of an American freeman away from you. Come along and git breakfast first."The unhurt rebel was standing there with his gun in hand, and had apparently been watching their approach for some time.

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