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: "The decline in Portuguese trade with China was accompanied with a corresponding decline in the language, but it left its impress upon the more recent pidgin English, which contains many Portuguese words. Pidgin English is a language by itself, with very little inflection either in noun, pronoun, or verb, and with a few words doing duty for many. The Chinese learn it readily, as they have no grammatical giants to wrestle with in mastering it, and the foreigners are quite ready to meet them on the road and adapt their phraseology to its requirements. The Chinese has only to commit to memory a few hundred words and know their meaning; the foreigner (if he be English-speaking) has less than a hundred foreign words to learn, together with the peculiar construction of phrases. The Chinese have printed vocabularies in which the foreign word and its meaning are set forth in Chinese characters, and thus they have no occasion to trouble themselves with the alphabet of the stranger. These books are specially intended for the use of compradores and servants in foreign employ, and are so small that they can be readily carried in the pocket.
  • 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:"We'll stop now and say good-bye. We have seen China and Japan, and had a splendid time. We think we have learned a great deal about the two countries, and hope that what we have written about them has been interesting to those for whom it was intended. We have tried to see things, and think of them without partiality or prejudice. We believe that the people of the East have the same claims to respect that ours have, and that it is only a narrow mind that sneers at the ways of others because[Pg 421] they are not like its own. We know that there are many things in which we are superior to the Orientals, but we also know that we have our weak points, and might be profitably instructed by those whom some of us affect to despise. And the more we know these patient and industrious people, the more we shall be likely to respect them. We are soon to leave China, perhaps never to see it again; but both China and Japan will always be pleasant recollections to both

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

  • 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:The Curate's hands became still. "Oh, dear." He wrestled with the blankness in his mind. "You're certainlyforgive me for saying itrather an odd person. I'm afraid we've both made a mistake, haven't we?"And then he told me about himself. He was a graduate of West Point, the only one on the brigade staff; was a widower, with a widowed brother, a maiden sister, two daughters, and a niece, all of one New Orleans household. The brothers and sister were Charlestonians, but the two men had married in New Orleans, twin sisters in a noted Creole family. The brother's daughter, I was told, spoke French better than English; the Major's elder daughter spoke English as perfectly as her father; and the younger, left in her aunt's care from infancy, knew no French at all. I wondered if they were as handsome as their white-haired father, and when I asked their names I learned that the niece, Ccile, was a year the junior of Estelle and as much the senior of Camille; but of the days of the years of the pilgrimage of any of the three "children" he gave me no slightest hint; they might be seven years older, or seven years younger, than his new clerk.
