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:Napoleon's saying about French revolutions was verified in 1830. The shock of the political earthquake was felt throughout the Continent, and severed Belgium from Holland. The inhabitants of Brussels began their revolt by resistance to local taxes, and ended by driving the[320] Dutch garrison out of the city, and proclaiming the independence of Belgium. The Duke of Wellington had no difficulty about the prompt recognition of the de facto Government of France. The change of dynasty had not been officially communicated to him many hours when he sent instructions to the British ambassador to enter into friendly relations with the new Government. He had not, however, the same facility in recognising the independence of Belgium. He had been instrumental in establishing the kingdom of the Netherlands; and he regarded the union as being a portion of the great European settlement of 1815, which ought not to be disturbed without the concurrence of the Great Powers by which it was effected. This hesitation on his part to hail the results of successful revolution added to his unpopularity. In the meantime a dangerous spirit of disaffection and disorder began to manifest itself in the south of England. Incendiary fires had preceded the Revolution in France, especially in Normandy, and they were supposed to have had a political object. Similar preludes of menaced revolution occurred during the autumn in some of the English counties nearest the French coast, in Kent, Sussex, Surrey, and Hampshire. Night after night, in the most fertile districts, the sky was reddened with the blaze of burning stack-yards. Crowds of the working classes, complaining of want of employment, went about throughout the country, breaking the threshing-machines, which had then come into extensive use. The Government were compelled to employ force to put down these disturbancesa fact which supplied inflammatory arguments to agitators, who denounced the Duke of Wellington as the chief cause of the distress of the working classes. Such was the state of things when the new Parliament met on the 26th of October.
  • 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:Meanwhile the aspect of foreign affairs was hardly reassuring. Britain was at war with China and Afghanistan, and within measurable distance of war with France and the United States. Postponing for the present our review of the first Afghan war and the differences with America, which will be dealt with more properly under the history of Sir Robert Peel's Ministry, we proceed to give a short sketch of the Chinese war and the Syrian crisis. The exclusive right of the East India Company to trade with China ceased on the 22nd of April, 1834, and from this time dates the great dispute about the opium traffic. The first free-trade ship sailed from England on the 25th of the same month. Lord Napier was sent out to China to superintend British commerce, and arrived at Macao on the 15th of July. He died soon after his arrival, and was succeeded by Mr., afterwards Sir, John Davis. But the Chinese were not disposed to recognise the authority with which he was vested. During 1835 and 1836 matters went on peaceably under the superintendence of the second and third Commissioners, Mr. Davis and Sir T. Robinson, the former of whom returned to England, and the latter was superseded by Captain Elliot, R.N., who in vain renewed the attempt to establish an official connection with the Chinese authorities. The opening of the trade in 1834 gave a powerful stimulus to all kinds of smuggling, and especially in opium, the importation of which into China was prohibited by the Imperial Government, in consequence of its deleterious qualities. During the following years, however, the supply of that drug was increased enormously, and the smuggling trade was carried on along the coasts of the northern provinces, in defiance of the laws of the country. The Imperial Government was naturally indignant at these encroachments, and became, moreover, seriously alarmed, perhaps not so much for its demoralising effects, as for the continued drain of specie which it occasioned. In March, 1839, Lin arrived at Canton, as Imperial High Commissioner, to enforce the laws in this matter. He immediately issued an edict requiring that every chest of opium on the river should be delivered up, in order to be destroyed; and that bonds should be given by traders that their ships should never again bring any opium, on pain of forfeiture of the article and death to the importer. Lin having taken strong measures to carry this edict into effect by blockading the British merchants, Captain Elliot proceeded to Canton, and issued a circular letter to his countrymen, requiring them to surrender into his hands all the opium then actually on the coast of China, and holding himself responsible for the consequences. On the 21st of May the whole of the opium, to the amount of 20,283 chests, was given up to the Chinese Government, and immediately destroyed. But even this great sacrifice did not propitiate Commissioner Lin. On the 26th of November he issued another interdict, ordering the cessation of all trade with British ships in a week; and in January, 1840, an Imperial edict appeared directing that all trade with Britain should cease for ever. Further numerous outrages were committed by the Chinese against British sailors. In consequence of these proceedings an armament was sent forth to teach the Chinese the principles of international law. The first part of the armament reached the Canton river in June, 1840, under the command of Captain Elliot. Having established a rigorous blockade in the river, the British, on the 5th of July, took possession of the large island of Chusan, in the Eastern Sea. It proved very unhealthy, and one man out of every four died. Proceeding still farther to the mouth of the Peiho, in the Yellow Sea, Captain Elliot attempted to overawe the Chinese. But the sea was too shallow to enable him to land his troops, and he was forced to put back to Chusan.

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

THREE:The French were driven again out of Naples by the end of July. Cardinal Ruffo brought down a wild army of Calabrians, and an army made up of Russians, Turks, Portuguese, and British, completed the expulsion of the Republicans and restored the king. In this restoration Nelson and his squadron took a most effective part; but unfortunately for his fame, he at this time became acquainted with Lady Hamilton, the wife of the British ambassador, and gave himself up entirely to her fascinations. Lady Hamilton was the friend of the Queen of Naples (a sister of the unfortunate Marie Antoinette), and she was said to have instigated Nelson to take a melancholy part in the savage retaliations of the court on the Neapolitan Republicans, but the charge has since been completely disproved. Nelson sent Commodore Trowbridge to Civita Vecchia to blockade it, and both that port and the castle of St. Angelo soon surrendered, and Captain Lewis rowed up the Tiber in his barge, hoisted the British colours on the Capitol, and acted as Governor of Rome till Pius VI., ejected by the French in the previous year, was nominally restored. The poor old man, however, never returned to his kingdom; he died at Valence, on the Rh?ne, on the 29th of August of this year. The election of the new Pope, Pius VII., did not take place till March, 1800. Before the end of the year, nearly all Italy, except Genoa, was cleared of the French.

THREE:Scarcely had Parliament ceased to sit, and the king was gone to spend the summer months in Germany, when the vigilance of the Ministry was demanded to ward off a fresh invasion. Alberoni, defeated in his schemes on France, and his hopes of the invasion of England by Charles XII. crushed by that monarch's death, determined now to make a grand effort to support the Pretender himself. For this purpose, he invited him to Spain, and at the same time began the equipment of a formidable fleet to carry over a Spanish force, under the command of the Duke of Ormonde, to the shores of Britain. The Pretender was not intended to accompany the expedition, but to be in readiness to follow on the first news of its[43] successful landing. But it was no more destined to reach these shores than the Grand Armada. It has always been the fate of invading squadrons to encounter providential tempests in coming hitherward, and the usual hurricane was ready to burst. Scarcely, indeed, had the fleet lost sight of Cape Finisterre before the storm swooped down upon it. For twelve days the terrible Bay of Biscay was swept by a frightful wind, which drove the vessels in all directions, and rendered it impossible to manage them. Fortunate would it have been if every vessel had failed to reach the shores at which they aimed; but two vessels, on board of which were the Earls Marshal and Seaforth, and the Marquis of Tullibardine, accompanied by about three hundred Spanish soldiers, reached Scotland, and landed, on the 16th of April, at Kintail, in Ross-shire. In the hope that Ormonde would still reach England, this small force lay quiet for some time, and so little did they excite notice, that the Government imagined that they had re-embarked. Their presence there, however, had the mischievous effect of exciting some few of the Highlanders to join them. They seized Donan Castle, and thus attracted the attention of the English. Some vessels of war arrived upon the coast. The castle was speedily retaken, and Lord Carpenter, the commander of the forces in Scotland, sent some troops from Inverness against them. General Wightman, the officer thus despatched, was attended by about a thousand men, and found the enemy, now swollen to about two thousand, strongly posted at Glenshiel. He immediately attacked them, and the miscellaneous force speedily dispersed. The Highlanders, who knew the country, rapidly disappeared amongst the hills, and the Spaniards had no other resource than to lay down their arms.On the other hand, the Corresponding Society and the Society for Constitutional Information kept up an open correspondence with the National Convention of France, even after the bloody massacres of September of this year, which we have yet to mention. Unwarned by these facts, they professed to see, in the example of Frenchmen, the only chance of the liberation of the English nation from the oppressions of the Crown and of an overgrown aristocracy. They made no secret of their desire to establish a Republic in Great Britain; and the Society for Constitutional Information included amongst its members a number of red-hot Americans. These Societies and the Revolutionary Society in London continued to send over glowing addresses to the French Convention, declaring their desire to fraternise with them for liberty and equality, and their determination never again to fight with Frenchmen at the command of despots.
