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:"Then I must lend you some books."Calverley was now forced to assume a courage which he did not feel; and looking sternly around, he asked, in as firm a voice as he could command, why he was thus surrounded? or whether they intended to make him a prisoner?
  • 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:Reuben did not speak, but a dull red crept over the swarthiness of his cheeks, and he turned away.The fight came, the battering of each other by two men, seemingly because of a private insult, really because they were representatives of two hostile groups, panting to be at each other's throats. They fought without science, staggering up and down, swinging arms like windmills, grabbing tufts of hair. At last old Buck Washington the bruiser could stand it no longer, and with a couple of clouts flung them apart, to bump on the ground and sit goggling stupidly at each other through trickles of blood.

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

THREE:"Well, lad," said his father, "so you're back at last."
  • 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:Towards the end of February there was a period of intense cold, and some heavy falls of snow. Snow was rare in that south-east corner, and all farm-work was to a certain extent dislocated. Reuben would have liked to spread blankets over his corn-fields and put shirts on his cattle. Adverse weather conditions never failed to stir up his inborn combativeness to its fiercest. His sons trembled as his brain raged with body-racking plans for fighting this new move of nature's. Richard was glad to be away from farmyard exertions, most of which struck him as absurd. He was now busy with the last of his lambing, the snow blew against the hut from the north-east, piling itself till nothing was to be seen from that quarter but a white lump. Inside was a crimson stuffiness, as the fumes of the brazier found their way slowly out of the little tin chimney. Sometimes before the brazier a motherless lamb would lie."Isabella," said the baron, as she entered, "Calverley has ascertained the retreat of Stephen Holgrave." She had anticipated something of the kind; but the effect it produced was singular. An electrical thrill seemed to vibrate through her frame, and a sudden coldness chilled her brow; but ere it could have been said that her cheek was pale, the whole countenance was suffused with a deepened glow, and rallying her energies, she asked, with assumed composure, "where he was hidden?"

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