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:But unfortunately for the Pretender, at the moment that the Swedish hero should prepare his armament for the earliest spring, the conspiracy exploded. Whilst the leaders of it had been flattering themselves that it was conducted with the profoundest secrecy, the English Ministry were in possession of its clue. As early as October they had found reason to induce them to intercept the correspondence of Gyllenborg, and had come at once on the letters of Gortz. The matter was kept close, and as nothing was apprehended in winter, Ministers used the time to improve their knowledge of the scheme from the inspected letters passing between Gortz and Gyllenborg. On the king's return it was resolved to act, and accordingly Stanhope laid the information regarding this formidable conspiracy before the Council, and proposed that the Swedish Minister, who had clearly, by conspiring against the Government to which he was accredited, violated the law of nations, and deprived himself of its protection, should be arrested. The Cabinet at once assented to the proposal, and General Wade, a man of firm and resolute military habits, was ordered to make the arrest of the Ambassador. The general found[37] Count Gyllenborg busy making up his despatches, which, after announcing laconically his errand, Wade took possession of, and then demanded the contents of his escritoire. The Dutch Government acted in the same manner to Gortz, and the evidence thus obtained was most conclusive.
  • 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:Whilst Walpole was thus labouring to secure the peace of Europe, Bolingbroke was as industriously at work to undermine him. He had cultivated his intimacy with the Duchess of Kendal still more diligently, and by liberal bribes, and more liberal promises if he succeeded in once more regaining power, he had brought her to exert her influence with the king in his favour. This most sordid and rapacious of mistresses, who looked on England only as a country to be managed for her benefit, ventured at length to put into the king's hand a memorial drawn up for her by Bolingbroke, demonstrating that the country must be absolutely ruined if Walpole continued in office. The stratagem was too palpable. Whilst she talked only, her suggestions might pass for her own, but the style of the document must have at once caused the king's suspicion of its true source. He put the paper into Walpole's hand. Walpole, after interrogating the two Turks, who were always in attendance on the king, and on their denying all knowledge of the means by which the missive reached the royal person, went directly to the Duchess and charged her with the fact. She did not deny it. Walpole advised the king to admit Bolingbroke to the audience which he solicited in the memorial, trusting that the king's dislike of him would prevail in the interview. The result appeared to be of that kind; nevertheless, Walpole was far from being secure in his own mind. He knew that the mistress would be continually returning to the charge in favour of her friend and paymaster, though she enjoyed a pension from Government of seven thousand five hundred pounds; and he even contemplated retiring with a peerage, but was dissuaded from this by the Princess of Wales and the Duke of Devonshire. On the other hand, Bolingbroke was in the highest expectation of his speedy restoration not only to rank but to office.

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

THREE:Two of the workmen from Butterley Foundry entered the "White Horse," which was kept by a widow Wightman, whose son George was deep in the foolish conspiracy into which Oliver and this his blind, savage tool, the Nottingham Captain, were leading him. They found Brandreth with a map before him, and telling them there was no good to be done, they must march up to London and overthrow the Government. He said all the country was rising; that at Nottingham the people had already taken the castle and seized the soldiers in their barracks, and were waiting for them. This shows that he had come straight from Oliver, who, on the 7th, was at Nottingham, attending the meeting there, and who knew that the meeting in Yorkshire had been prevented. Yet he had allowed the people of Nottingham to believe that the Yorkshire men were coming, according to agreement, in thousands; and he allowed Brandreth to go and arouse Derbyshire, under the belief that Nottingham that night would be in the hands of the insurgents. On Monday night, the 9th of June, Brandreth and a knot of his colleagues proceeded to muster their troop of insurgents for the march to Nottingham. They roused up the men in their cottages, and, if they refused to go, they broke in the doors with a crowbar, and compelled them to join them. Most of these unwilling levies slipped away in the dark on the first opportunity. At South Wingfield he assembled his forces in an old barn, and then they proceeded through the neighbourhood demanding men and guns. An old woman had the courage to tap the "captain" on the shoulder, and say"My lad, we have a magistrate here;" and many of the men thought Brandreth must be mad or drunk. At the farm of widow Hetherinton he demanded her men and arms, and when she stoutly refused him, he put the gun through[127] the window and shot one of her men dead. As the day dawned, Brandreth and his infatuated troop appeared before the gates of Butterley Foundry, and demanded the men; but Mr. Goodwin, the manager, had been apprised of their approach, and had closed the gates. Brandreth had planned to take Butterley Foundry, and carry away not only the men but a small cannon kept there; but Mr. Goodwin went out and told Brandreth he should not have a man for any such insane purpose, and seeing an old man that he well knew, Isaac Ludlam, who bore a good character, and had been a local preacher amongst the Methodists, he seized him by the collar and pushed him into the foundry court, telling him not to be a fool, but stay at home. Ludlam, however, replied, "he was as bad as he could be," rushed out, and went onto his death; for he was one of those that were executed.

THREE:This result was due to important negotiations behind the scenes. For many months the more extreme section of the Cabinet had urged Lord Grey to recommend the king to swamp the hostile majority by a creation of peers. Both he and Althorp objected to this course, and fresh overtures were made to the waverers, while the king undertook to convert the Bishops. Both attempts[348] failed, and then the Cabinet was nearly rent in twain. Lord Durham attacked his father-in-law in language which Althorp declared to be "brutal," and for which, said Lord Melbourne, he deserved to be knocked down. At last the king resolved to agree to a creation of peers on condition that the new creations should not exceed the number of 24. This alarmed the waverers, and with the aid of Charles Greville they came to terms with the Government. Lord Harrowby and Lord Wharncliffe secured a majority on the second reading, on condition that no new peers should be created.The year 1771 opened in circumstances which greatly diminished the interest in Parliamentary proceedings. As all reporting was excluded from the House of Lords, the chief speakers there felt that they were no longer addressing the nation, but merely a little knot of persons in a corner, and consequently the stimulus of both fame and real usefulness was at an end. In the Commons, the desire of the Ministry to reduce that popular arena to the same condition of insignificance produced a contest with the City as foolish and mischievous in its degree as the contests then going on with Wilkes and America. George Onslow, nephew of the late Speaker, and member for Guildford, moved that several printers, who had dared to report the debates of the House of Commons, should be summoned to the bar to answer for their conduct. Accordingly, these mediums of communication between the people and their representatives were summoned and reprimanded on their knees. One of their number, named Miller, however, declared that he was a liveryman of London, and that any attempt to arrest him would be a breach of the privileges of the City. The Serjeant-at-Arms dispatched a messenger to apprehend this sturdy citizen, and bring him before the House; but, instead of succeeding, the Parliamentary messenger was taken by a City constable, and carried before Brass Crosby, the Lord Mayor. With the Lord Mayor sat Alderman Wilkes and Alderman Oliver. It was delightful work to Wilkes thus to set at defiance the House of Commons, which had made such fierce war on him. The Lord Mayor, accordingly, was fully confirmed in his view that the messenger of the Commons had committed a[204] flagrant violation of the City charter, in endeavouring to lay hands on one of its liverymen within its own precincts, and they held the messenger accordingly to bail. The House of Commons was fired with indignation at this contemptuous disregard of their dignity. They passed a resolution, by a large majority, ordering the Lord Mayor and the two aldermen to appear at their bar. Wilkes bluntly refused to attend the House in any shape but as a recognised member of it. Crosby pleaded a severe fit of the gout; and Oliver, though he appeared in his place, refused to make any submission whatever, but told them he defied them. The House, in its blind anger, resolved that Oliver should be committed to the Tower, and Crosby to the custody of the Serjeant-at-Arms. But Crosby declared that he would not accept this indulgence at the hands of the House, but would share the incarceration of his honourable friend; and he was accordingly sent also to the Tower. The people out of doors were in the highest state of fury. They greeted the City members on their way to and from the House, but they hooted and pelted the Ministerial supporters. Charles James Fox, still a Government man, as all his family had been, was very roughly handled; Lord North's carriage was dashed in, and himself wounded; and had he not been rescued by a popular member, Sir William Meredith, he would probably have lost his life. The Commons had engaged in a strife with the City, in which they were signally beaten, and no further notice being taken of the printers, from this time forward the practice of reporting the debates of Parliament became recognised as an established privilege of the people, though formally at the option of the House; and so far now from members or Ministers fearing any evil from it, the most conservative of them would be deeply mortified by the omission of their speeches in the reports. The termination of the Session also opened the doors of the Tower, and liberated the Lord Mayor and Alderman Oliver. They were attended from the Tower to the Mansion House by the Corporation in their robes, where a banquet celebrated their restoration to freedom, and the populace displayed their sympathy by bonfires and illuminations.
