TWO:"What are you gazing at, Byles," asked Calverley.

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:"Reckon I can," said Albert good-naturedly, knowing that some day he might want his brother to do the same for him."Aye, ye may soon sleep your last sleep. They will have at ye in the morning; for the proud barons are gathering their might; but, by St. Nicholas! I may do something yet. Yes, there will be more bloodI see it;I must have an order to behead the lords; and then, if Richard will be king of the commons, and no more lords or bondage, father John himself could not wish for more."
  • 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:When all were assembled, Calverley stated that Stephen Holgrave, having refused to swear that he would not again take advantage of his liberty to flee from bondage, the baroness not wishing, from a feeling of clemency, to punish his obstinacy farther, had desired him to declare that she should hold each bondman responsible for the appearance of Holgrave, and should consider their moveables and crops forfeited in the event of his absconding.

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

THREE:
  • 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:In time his struggle began to modify his relations with Rose. At first he had told himself that her uselessness was only apparent. Though she herself did no fighting, she gave such rest and refreshment to the soldier that he went forth strengthened to the war. He had almost begun to attribute to her his daily renewed courage, and had once or twice been moved to show his gratitude by acts of expensive indulgence.
