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:His terms were rejected with disdain. Yet he had a last interview with Metternich, in which he hoped to terrify him by a dread of the future preponderance of Russia; but, seeing that it made no impression, he became incensed, and adopted a very insolent tone towards the Austrian Minister. "Well, Metternich," he demanded, "how much has England given you to induce you to play this part towards me?" Metternich received the insult in haughty silence. Buonaparte, to try how far the diplomatist still would preserve his deference towards him, let his hat fall: Metternich let it lie. This was a sign that the Austrian had taken his part; it was, in fact, the signal of war. Yet, at the last moment, Napoleon suddenly assumed a tone of conciliation, and offered very large concessions. He had heard the news of the defeat of Vittoria. But it was too late. The Congress terminated on the 10th of August, and the Allies refused to re-open it. On the 12th of August, two days after the termination of the armistice, Austria declared herself on the side of the Allies, and brought two hundred thousand men to swell their ranks. This redoubtable force was commanded by her general, Prince von Schwarzenberg.Notwithstanding these checks at Emsdorf and Warburg, the French obtained possession of G?ttingen and Cassel. Ferdinand attempted, but in vain, to dislodge them from G?ttingen, and the hereditary Prince, attempting to surprise the Marquis de Castries at Wesel, was repulsed with a loss of one thousand two hundred men at Closter-Campen, near that town, and was compelled to retreat. This closed the campaign, and the French took up their winter quarters at G?ttingen and Cassel.
  • 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:

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

THREE:On the 23rd the aspect of the insurgent multitude became more fierce, daring, and determined. Guizot had announced the resignation of his Cabinet; the king had sent for Count Mol, then for M. Thiers, who was asked to form a new Ministry. He declined unless Odillon Barrot became one of his colleagues. The king gave a reluctant consent, but Barrot was not prepared to sanction measures of military repression. Marshal Bugeaud, the hero of Algiers, whose exploits there made his name terrible, had been appointed Commander-in-Chief of the first military division, and of the National Guard of Paris, but the National Guard were not prepared to fight against the people. The people, knowing this, shouted, "Vive la Garde Nationale!" and the National Guard shouted, "Vive la Rforme!" In the evening, about seven o'clock, an immense body of the working classes formed in procession, headed by men carrying blazing torches, and marching along the Boulevards, chanted two lines of the Girondists' song
  • 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:During this brilliant campaign in Italy, Moreau, in Germany, had beaten General Kray in several engagements, advanced to Ulm, and there, crossing the Danube, had overrun a great part of Bavaria, and had made himself master of Munich and menaced Vienna. On hearing of the armistice in Italy, the Emperor demanded one for Austria, to continue till September; and Buonaparte, seeing that the Czar Paul had ceased to support Austria, recommended the Emperor to make peace with[478] France. The Emperor required that Britain should be included in it. But Napoleon demanded a separate negotiation, which Austria was afraid to grant. No sooner was this answer received in Paris than Buonaparte gave the word for renewed and vigorous action, both in Italy and Germany. Moreau advanced by Salzburg towards Vienna, whilst Brune drove the Austrians from the Mincio, and over the Adige and the Brenta to the very vicinity of Venice, whilst Macdonald occupied the passes of the Tyrol, ready to march to the support of the army either in Italy or Germany. The Archduke John met Moreau near Haag, and for a moment worsted him; but on the 2nd of December the two armies came to a general engagement at Hohenlinden, between the rivers Iser and Inn, in which the Austrians were routed, with a loss of ten thousand men. Moreau advanced and occupied Salzburg, and trembling for the safety of Vienna itself, the Emperor hastened to make peace. An armistice was signed on the 25th of December, and the treaty was concluded at Lunville on the 9th of February, 1801. By this treaty all the conditions of the Treaty of Campo Formio were renewed, and the frontier of the Rhine was again ceded to France.In the midst of this prosperous career the two brothers-in-law, the Ministers, began to differ in their views, and Lord Townshend was soon driven by the overbearing conduct of Walpole to resign. Lady Townshend, the sister of Walpole, and even Queen Caroline, exerted their influence for some time to put an end to these feuds; but Lady Townshend soon died, and the queen, finding the breach inevitable, took the side of Walpole as the more indispensable servant of the Crown. There were serious topics on which Townshend and Walpole differed, both domestic and foreign. Townshend did not approve of the length to which matters were carried against the Emperor, and he was weary of the timid temper of the Duke of Newcastle, and strongly urged his dismissal, and the employment of Lord Chesterfield in his place; but a Pension Bill brought the quarrel to a crisis. The object of the Bill, which was warmly supported by the Opposition, was to prevent any man holding a pension, or who had any office held in trust for him, from sitting in Parliament. The king privately styled it "a villainous Bill, which ought to be torn to pieces in every particular." Both Walpole and Townshend were of the same opinion; but Townshend was for openly opposing it, Walpole for letting it pass the Commons, and be thrown out in the Lords. Townshend, to whom the odium of rejecting it was thus carried in the Lords, protested against this disingenuous conduct on the part of Walpole, and assured him that the trick would soon be fully observed, and bring more unpopularity on him in the end than a manly, open oppositionwhich it did.
