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:
  • 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:At the time of this armistice, Napoleon, by the great battles of Lützen and Bautzen, had recovered his prestige sufficiently to induce the German Confederates of the Rhine to stand by him; but he was by no means what he had been. The[67] opinion of his invincibility had been irreparably damaged by the Russian campaign, and the success in these battles was not of a character to give confidence to his own army. They saw that the Allies had lost all superstitious fear of him. To assist in the negotiations of this armistice, Buonaparte sent for his two ablest heads, Fouch and Talleyrand, whom he had so long thrown from him for their sound advice. If Buonaparte could have heard, too, what was really going on in France, what were the growing feelings there, he would have been startled by a most ominous condition of things. But he had thoroughly shut out from himself the voice of public opinion, by his treatment of the press and of liberty, and he now was to suffer for it. Great Britain, on the 14th of June, had concluded an alliance with Russia and Prussia, and promised to send ample materials of assistance, even an army to the north of Prussia; and many British officers of the highest rank repaired to the headquarters of the Allies. When Great Britain was asked to take part in this negotiation she refused, declaring it useless, as Napoleon would not grant the only demands which the Allies ought to make.

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

THREE:Buonaparte, seeing that nothing was to be expected from the Chambersfor even the Peers adopted the resolutions of the Representativeswho had already demanded his abdicationassumed the air of the despotic emperor, and demanded of Carnot that he should issue orders for a levy of three hundred thousand men, and should find supplies. Carnot said both propositions were impossible. Napoleon then summoned, on the night of the 21st, a general council, consisting of the late Ministers, the Presidents, and Vice-Presidents of the two Chambers, where Regnault and Maret recommended a show of resistance whilst offering terms of peace; but Lafayette said that would only make matters worse. The Allies were victorious, and there was but one course for the Emperor; and Lanjuinais and Constant supported that view. On the 22nd the Chamber of Representatives met early, and again demanded an act of abdication. Napoleon complied, but, as on his former abdication, only in favour of his son. The Chamber thanked him, but took no notice of the clause in favour of Napoleon II. But Lucien Buonaparte[103] and Labdoyre, in violent language, pressed on the House of Peers the recognition of Napoleon II. They persisted in passing it quietly over; but they required Napoleon to issue a proclamation to the army, declaring his abdication, without which the soldiers would not believe it, and, to conciliate them, he complied. Still, fearing lest he should put himself at the head of Grouchy's division, or some other, though small, troublesome force, they insisted that he should retire to Malmaisonso long the favourite abode of the repudiated Josephine, With this, too, he complied, but immediately discovered that he was surrounded by Guards, and was in fact a prisoner. General Becker was appointed to have surveillance over Napoleon; and it was supposed that, as Becker had personal cause of resentment against him, this surveillance would be rigorous. But Becker was a man of honour; he respected the misfortunes of a man who, whatever had been his crimes, had made himself almost master of the world, and he treated him with the utmost courtesy. Orders were issued by the Provisional Government for two frigates to convey Napoleon to the United States, and Becker was to allow of his retirement to Rochefort, in order to his embarkationto accompany him there, but not to permit his movement in any other direction.

THREE:The great difficulties of the Government at this time were the settlement of the questions with Spain of the right to cut logwood in the bay of Campeachy, and the retention of Gibraltar. The Spaniards had frequently resisted the cutting of logwood in the Bay of Campeachy by the English; and in 1717 the Marquis of Monteleone had presented a memorial against it; but the Board of Trade contended that the practice was of old standing, and amounted to a right. This representation was now laid before the House of Commons, and was backed by many petitions from the merchants of London and other places, complaining of the interruptions to their trade to the South American and West Indian colonies, which had been carried on by connivance rather than by actual permission of Spain. There was a great fermentation in the public mind on these subjects, and the Minister was accused of tamely submitting to national injuries. The nation seemed ready to rush into a war with Spain, and perhaps all the more so that the king, in his opening speech, had observed that "an actual war was preferable to such a doubtful peace, but that the exchange was very easy to be made at any time."
