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:Chapter 14
  • 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:Her bold sweet eyes were looking into his and her mouth was curved like a heart.

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

THREE:The abbot looked frowningly on father John, as he again took up the pen. "My son, you are not serving the church by such pertinacity. This application will only expose one of its dignitaries to humiliation; however, I shall write to the Baron, since you desire it, and demand that the accused be transferred to the tribunal over which we preside."
  • 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:On the day the prohibitory writ left London, a small iron box, with a superscription, addressed to Thomas Calverley, was left by a stranger at Sudley Castle, and immediately after, by another messenger, a packet, in which, within many envelopes, a key was concealed. Calverley, naturally concluding that this key belonged to the box he had just received, with a variety of perplexing conjectures, unlocked it, and beheld the crimson damask dress of a pursuivant, on which the royal arms were embroidered in gold, and beneath the dress a purse of gold coin and a scroll of parchment, on which the following was written, evidently in a disguised hand:Holgrave trembled; he cast a longing eager glance towards the door. Margaret was in the pains of labour, brought on by the shock she received on his arrest; and this it was that caused him to hesitate. His face brightened as he beheld the animated ruddy face of a serving boy, who breathlessly approached. He bent forward his head to catch the whispered intelligence that told him he was a father, and then, with a joy which he strove not to conceal, announced his selection in a single word"bondage!"

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