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:I see a light, Sandy said as the airplane swung far out over the dark water. A green light, but the hydroplane wouldnt carry lights.
  • 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:He went the next day but one, riding out of the post at daylight. And he saw Felipa once more. She was standing by the creek, drawing an arrow from her quiver and fitting it to her bow. Then she poised the[Pg 32] toe of her left foot lightly upon the ground, bent back, and drew the bow almost to a semicircle. The arrow flew straight up into the shimmering air, straight through the body of a little jay, which came whirling, spinning down among the trees. Felipa gave a quick leap of delight at having made such a shot, then she darted down in search of the bird. And Cairness rode on.

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

THREE:[See larger version]In 1710 was established the Academy of Ancient Music, the object of which was to promote the study of vocal and instrumental harmony. Drs. Pepusch, Greene, and other celebrated musicians were amongst its founders. They collected a very valuable musical library, and gave annual concerts till 1793, when more fashionable ones attracted the public, and the society was dissolved. In 1741 was established the Madrigal Society, the founder of which was John Immyns, an attorney. It embraced men of the working classes, and held meetings on Wednesday evenings for the singing of madrigals, glees, catches, etc. Immyns sometimes read them a lecture on a musical subject, and the society gradually grew rich. The composers of such pieces at this period were such men as Purcell, Eccles, Playford, Leveridge, Carey, Haydn, Arne, etc. Public gardens became very much the fashion, and in these, at first, oratorios, choruses, and grand musical pieces were performed, but, by degrees, gave way to songs and catches.[157] Vauxhall, originally called Spring Garden, established before the Revolution, became all through this period the fashionable resort of the aristocracy, and to this was added Ranelagh, near Chelsea College, a vast rotunda, to which crowds used to flock from the upper classes on Monday, Wednesday, and Friday evenings, to hear the music and singing. These performances spread greatly the taste for music, and probably excited the alarm of the puritanically religious, for there arose a loud outcry against using music in churches, as something vain and unhallowed. Amongst the best publications on the science of music during this period were Dr. Holder's "Treatise on the Natural Grounds and Principles of Harmony," 1694; Malcolm's "Treatise on Music, Speculative, Practical, and Historical," 1721; Dr. Pepusch's "Treatise on Harmony," 1731; Dr. Smith's "Harmonics; or, the Philosophy of Musical Sounds;" Avison's "Essay on Musical Expression," 1752. Avison also published twenty-six concertos for a band, which were much admired.
  • 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:Fox did not suffer the Session to close without another powerful effort to avoid war with France. A petition had been handed to him for presentation to the Commons, drawn up by Mr. Gurney of Norwich, and signed by the Friends and other inhabitants of that city, praying that peace with France might be concluded. Fox not only agreed to present it and support its prayer, but he earnestly exhorted Mr. Gurney and his friends to promote the sending of petitions from other places for this object, as the only means of influencing the House, bent determinedly on war. On the 17th of June, only four days before the close of the Session, Fox moved an Address to the Crown, praying that, as the French had been driven out of Holland, peace should be made. In pursuance of his objecta great one, if attainablehe did not spare his former favourite, the Empress of Russia, and the other royal robbers of Poland. Burke replied that Fox knew very well that the defence of Holland was but a very partial motive for the war. The real obstacles to peace were the avowed principles of the Frenchthose of universal conquest, of annexation of the kingdoms conquered, as already Alsace, Savoy, and Belgium; their attempts on the Constitution of Great Britain by insidious means; the murder of their own monarch held up as an example to all other nations. To make peace with France, he said truly, was to declare war against the rest of Europe, which was threatened by France; and he asked with whom in France should we[418] negotiate for peace, if so disposed? Should it be with Lebrun, already in a dungeon, or with Clavire, who was hiding from those who were anxious to take his head? or with Egalit, who had been consigned to a dungeon at Marseilles? Burke declared that you might as well attempt to negotiate with a quicksand or a whirlwind as with the present ever-shifting and truculent factions which ruled in France."We have tea at five," Mrs. Kirby told him, as they finished, and her husband started out to superintend and help with the digging of an acequia.
