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:[See larger version]
  • 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 winter of 1836-7 was marked by great commercial activity, and a strong tendency to over-trading, chiefly on the part of the banks. The result was a reaction, and considerable monetary embarrassment. In the reckless spirit of enterprise which led to these consequences, the American houses took the lead. The American speculators indulged an inordinate thirst for gain by land jobs, and over-trading in British produce. The most remarkable examples of this were afforded by three great American houses in London, called "the three W.'s." From an account of these firms, published in June, 1837, it appeared that the amount of bills payable by them from June to December, was as follows: Wilson and Co.,[411] 936,300; Wigan and Co., 674,700; Wildes and Co., 505,000; total acceptances, 2,116,000. This was upwards of one-sixth of the aggregate circulation of the private and joint-stock banks of England and Wales, and about one-eighth of the average circulation of the Bank of England. The shipments to America by Wigan and Co. amounted to 1,118,900. The number of joint-stock banks that started into existence at this time was remarkable. From 1825 to 1833 only thirty joint-stock banks had been established. In that year the Charter of the Bank of England being renewed, without many of the exclusive privileges it formerly enjoyed, and the spirit of commercial enterprise being active, joint-stock banks began to increase rapidly. There was an average of ten new companies annually, till 1836, when forty-five of these establishments came into existence in the course of ten months. In Ireland there were ten started in the course of two years. The consequence of this greatly increased banking accommodation produced a wild spirit of commercial adventure, which collapsed first in America, where the monetary confusion was unexampledbankers, importers, merchants, traders, and the Government having been all flung into a chaos of bankruptcy and insolvency. This state of things in America had an immediate effect in England. Discounts were abruptly refused to the largest and hitherto most respectable houses of Liverpool and London. Trade, in consequence, became paralysed; prices suddenly dropped from thirty to forty per cent.; and the numerous share bubblesthe railway projects, the insurance companies, the distillery companies, the cemetery companies, the sperm oil, the cotton twist, zoological gardens, and other speculationswhich had floated on the pecuniary tide, all suddenly collapsed, and there was an end to the career of unprincipled adventurers. It is satisfactory, however, to observe that the sound commerce of the country soon recovered the shock thus given; and in less than two years the pecuniary difficulties had passed away. Commerce had resumed its wonted activity, and flowed steadily in legitimate channels. The American banks resumed payment, and the three great American houses, which had involved themselves to such an enormous extent, were enabled to meet all their liabilities.

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

THREE:The time for the last grand conflict for the recovery of their forfeited throne in Great Britain by the Stuarts was come. The Pretender had grown old and cautious, but the young prince, Charles Edward, who had been permitted by his father, and encouraged by France, to attempt this great object in 1744, had not at all abated his enthusiasm for it, though Providence had appeared to fight against him, and France, after the failure of Dunkirk, had seemed to abandon the design altogether. When he received the news of the battle of Fontenoy he was at the Chateau de Navarre, near Evreux, the seat of his attached friend, the young Duke de Bouillon. He wrote to Murray of Broughton to announce his determination to attempt the enterprise at all hazards. He had been assured by Murray himself that his friends in Scotland discountenanced any rising unless six thousand men and ten thousand stand of arms could be brought over; and that, without these, they would not even engage to join him. The announcement, therefore, that he was coming threw the friends of the old dynasty in Scotland into the greatest alarm. All but the Duke of Perth condemned the enterprise in the strongest terms, and wrote letters to induce him to postpone his voyage. But these remonstrances arrived too late; if, indeed, they would have had any effect had they reached him earlier. Charles Edward had lost no time in making his preparations.The supplies and the Mutiny Bill were now passed without much difficulty, but Ministers did not venture to introduce an Appropriation Bill. On the 23rd, Lord North, stating that the dissolution of Parliament was confidently asserted out of doors, declared that such a dissolution, without passing an Appropriation Bill, would be an unparalleled insult to the House. He expressed his astonishment that the Minister did not condescend to utter a syllable on the subject of the proposed change. Pitt, now confident of his position, replied that gentlemen might ask as many questions as they pleased; that he had adopted a course which was advantageous to the country, and did not feel bound to enter then into any explanations. All mystery, however, was cleared up the next day, for the king went down to the House of Lords and prorogued Parliament, announcing that he felt it his duty to the Constitution and the country to convoke a new Parliament. Accordingly, on the following day, the 25th of March, he dissolved Parliament by proclamation.
