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 Frankfort Parliament had spent a year doing nothing but talking. They came, however, to the important resolution of offering the Imperial Crown of Germany to the King of Prussia. As soon as the Prussian Assembly heard this, they adopted an address to the king, earnestly recommending him to accept the proffered dignity. They were deeply interested by seeing the house of Hohenzollern called to the direction of the Fatherland and they hoped he would take into his strong hands the guidance of the destinies of the German nation. On the 3rd of April, 1849, the king received the Frankfort deputation commissioned[578] to present to him the Imperial Crown. He declined the honour unless the several Governments of the German States should approve of the new Imperial Constitution, and concur in the choice of the Assembly. As soon as this reply was made known, the second Prussian Chamber adopted a motion of "urgency," and prepared an address to the king, entreating him to accept the glorious mission of taking into firm hands the guidance of the destiny of regenerated Germany, in order to rescue it from the incalculable dangers that might arise from the conflicting agitations of the time. The address was carried only by a small majority. The king had good reason for refusing the imperial diadem; first, because Austria, Würtemberg, Bavaria, and Hanover decidedly objected; and secondly because the king required changes in the Frankfort Constitution which the Parliament refused to make. These facts enabled his Majesty to discover that the imperial supremacy was "an unreal dignity, and the Constitution only a means gradually, and under legal pretences, to set aside authority, and to introduce the republic." In July the state of siege was terminated in Berlin, and the new elections went in favour of the Government.Whilst affairs with Holland were in this position, Count Florida Blanca, the Spanish Minister, had adopted the system of seizing all neutral vessels, of whatever nation, that were found carrying British goods, and conveying them into Spanish ports as lawful prizes. This, as he calculated, raised the resentment of all the neutral PowersRussia, Sweden, Denmark, Prussia, Holland, and the trading States of Italywho denounced these outrages on their flag. But Florida Blanca replied, that so long as England was suffered to pursue this system, Spain must continue to make reprisals; that it was, however, in the power of the neutral nations to combine and defend their flags, by compelling England to desist. The result was as he had hoped. Catherine of Russia, who had hitherto considered herself an ally of Englandwho had, at one time, contemplated furnishing soldiers to assist in reducing the American rebels, and who protested against the monstrosity of France encouraging the colonies of England to throw off their allegiancewas suddenly induced to change her tone. On the 26th of February she issued her famous proclamation, "that free ships should make free goods." This meant that all neutral nations should continue to carry all kinds of articles to Powers at war with one another, without search or question, except such goods as were expressly specified in treaties. Sweden, Denmark, Prussia, France, and Spain, all readily entered into this league, which assumed the name of the "Armed Neutrality," the object of which, though ostensibly to control all belligerent Powers, was really to suppress the naval power of England. Holland eulogised this league, but did not yet venture to join it; but prohibited the exportation of stores to our garrison in Gibraltar, whilst her ships were busy carrying supplies to the Spanish besiegers. Sir Joseph Yorke, therefore, on the 21st of March, 1780, informed the States that, unless the stipulated help was furnished within three weeks, England would suspend, pro tempore, the regulations in favour of the Dutch commerce. The States still refused to furnish the succours, and at the specified time the privileges in question were suspended, though Count Welderen still continued in London, and Sir Joseph Yorke at the Hague. It was evident that Holland could not[273] long continue in this position, and Frederick of Prussia was soliciting Catherine of Russia to enter into an engagement to protect the Dutch commerce in every quarter of the globe. If Frederick could have prevailed, he would have stirred up a universal crusade against England; but Catherine was not rash enough for this quixotism.
  • 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:FROM THE PAINTING BY CLARKSON STANFIELD, R.A., IN THE CORPORATION ART GALLERY, GUILDHALL.Blucher's headquarters were at Namur, his right extending to Charleroi, near the left of Wellington, and his left and reserves covering Gevil and Lige. His force amounted to eighty thousand men, supplied with two hundred cannon. On the 15th Buonaparte addressed his army, telling them that the enemies arrayed against them were the same that they had so often beaten, and whom they must beat again if they were the men they had been. "Madmen!" he exclaimed, "the moment of prosperity has blinded them. The oppression and humiliation of the French people are beyond their power. If they enter France they will there find their tomb!" This address had such an effect that the French advanced with all the spirit of their former days. They swept the western bank of the Sambre of the Prussian outposts; they advanced to Charleroi, drove out the Prussians under Ziethen, and compelled them to fall back on the village of Gosselies, and thence to Ligny and St. Amand. It was now seen that the object of Buonaparte was to cut off the communication between the Prussians and British, and defeat the Prussians first, instead of having to fight the two armies at once. To complete this Ney had been dispatched to attack and drive back the British advance at Quatre Bras and Frasnes; but, hearing firing in the direction of Charleroi, which was the engagement with Ziethen, he sent a division to support the French there, and thus found his main body too weak to move the British at Quatre Bras. For doing this without orders, Buonaparte reprimanded Ney, as he afterwards did Grouchy for too implicitly following his orders in pursuit of Blucher.

THREE:From the sublime to the ridiculous is but a step. A scene followed the king's departure which seems almost incredible. After the service of the second course, the numerous attendants, singers, and even ladies and gentlemen began to press round the royal table, as if prepared for a scramble to possess its contents. The crowd of spectators pressed nearer and nearer. For a moment only covetous eyes were cast on the spoils, as if each were afraid to begin the plunder; but, at last, a rude hand having been thrust through the first ranks, and a golden fork having been seized, this operated as a signal to all, and was followed by a "general snatch." In a short time all the small portable articles were transferred to the pockets of the multitude. The Lord High Chamberlain, hearing of the attack, hastened to the rescue, and[216] with the greatest difficulty saved the more important articles of plate, and had them conveyed to Carlton Garden. Then followed a scene unparalleled in the annals of coronations. The crowds in the galleries had beheld with envy the operations at the banquet. They were very hungry, and very thirsty, and seeing now that Westminster Hall was "liberty hall," they rushed down different stairs and passages, and attacked the viands and the wine. A raging thirst was the first thing to be satisfied, and in a few minutes every bottle on the table was emptied. A fresh supply was soon obtained from the cellarettes. When the ravening selfishness of the hungry crowd was satisfied, the gentlemen recovered their politeness, and began to think of the ladies. Groups of beautiful women then found their way to the tables, and every effort was made to afford them the refreshment of which they stood so much in need. In the meantime, the plunderers took advantage of the confusion to enrich themselves with trophies, breaking and destroying the table ornaments to obtain fragments of things too cumbrous to carry away. Thus, baskets, flowerpots, vases, and figures were everywhere disappearing, and these were followed by glasses, knives, forks, salt-spoons, and, finally, the plates and dishes. The last were engraved with the royal arms and the letters "Geo. IV.," and were therefore specially coveted as memorials. The dirty state of the articles, however, was rather out of keeping with the costly dresses; but the ladies and gentlemen got over the difficulty by wrapping up the articles in their pocket-handkerchiefs. Having thus secured all the spoils they could, they made all possible haste to their carriages. At a subsequent period, it was with the greatest difficulty that the royal plate could be kept from being carried away by the multitude outside when the barriers were removed.
