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:274The methodical distinction between the materials for generalisation and generalisation itself, is derived from the metaphysical distinction between Matter and Form in Nature.539 This distinction is the next great feature of Bacons philosophy, and it is taken, still more obviously than the first, from Aristotle, the most manifest blots of the original being faithfully reproduced in the copy. The Forms375 of simple substances were, according to the Stagirite, their sensible qualities. The Forms of aggregates were the whole complex of their differential characteristics. And although the formal cause or idea of a thing was carefully discriminated from its efficient and final causes, it was found impossible, in practice, to keep the three from running into one. Again, the distinction between single concepts and the judgments created by putting two concepts together, although clearly conveyed by the logical distinction between terms and propositions, was no sooner perceived than lost sight of, thanks to the unfortunate theory of essential predication. For it was thought that the import of universal propositions consisted either in stating the total concept to which a given mark belonged, or in annexing a new mark to a given concept. Hence, in Aristotles system, the study of natural law means nothing but the definition and classification of natural types; and, in harmony with this idea, the whole universe is conceived as an arrangement of concentric spheres, each receiving its impulse from that immediately above it. Precisely the same confusion of Form, Cause, and Law reigns throughout Bacons theory of Nature. We do, indeed, find mention made of axiomata or general propositions to a greater extent than in the Organon, but they are never clearly distinguished from Forms, nor Forms from functions.540 And although efficient and material causes are assigned to physics, while formal and final causes are reserved for metaphysicsan apparent recognition of the wide difference between the forces which bring a thing into existence and the actual conditions of its stability,this arrangement is a departure from the letter rather than from the spirit of Aristotles philosophy. For the efficient causes of the De376 Augmentis answer roughly to the various kinds of motion discussed in the Physics and in the treatise On Generation and Corruption; while its Forms are, as we have seen, identified with natural causes or laws in the most general sense.
  • 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:Anybody who remained in England would have tohed be left there. But Mr. Whiteside leaned forward and spoke meaningly, a man sailed from Englandand although I did not know it at the time, I have checked up, since, and the man from London is an English circus acrobatwho went in for stunting on airplanes.

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

THREE:Others of the troops were ordered in, and among them was Landor's. It had gone out for a twenty days' scout, and had been in the field two months. It was ragged and all but barefoot, and its pack-train was in a pitiable way. Weeks of storm in the Mogollons and days of quivering heat on the plains had brought its clothing and blankets to the last stages.

  • 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:Not a week beforeand then the Agency had been officially at peacea Mexican packer had been shot down by an arrow from some unseen bow, within a thousand yards of the post, in broad daylight. The Indians, caking their bodies with clay, and binding sage or grass upon their heads, could writhe unseen almost within arm's reach. But Felipa was not afraid. Straight for the river bottom she made, passing amid the [Pg 78]dump-heaps, where a fire of brush was still smouldering, filling the air with pungent smoke, where old cans and bottles shone in the starlight, and two polecats, pretty white and black little creatures, their bushy tails erect, sniffed with their sharp noses as they walked stupidly along. Their bite meant hydrophobia, but though one came blindly toward her, she barely moved aside. Her skirt brushed it, and it made a low, whining, mean sound.
