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 horse stopped, and she reeled blindly in her seat into a pair of strong arms that caught her and drew her down. A voice was saying words she could not hear, but she knew the voice so well. And she smiled and dropped her head down upon her husband's shoulder. "Justjust in time," she whispered very low.
  • 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:Scarcely was the Rockingham Administration formed when they determined to recall England's ablest admiral, Sir George Rodney, and they carried this into execution in May of this year, and appointed Admiral Pigott in his stead. Lord Keppel, who had shown himself so sensitive in his own case, now he was at the head of the Admiralty not only recalled Rodney because he was of another party, but he did it in the coldest and most direct manner, through his secretary, Mr. Stephen. However, before this order of recall was issuedthe 1st of MayRodney had fought one of the greatest and most decisive battles which adorn the history of our navy. He had gone in all haste to the West Indies, with fourteen ships of the line, to join Sir Samuel Hood, who was vainly contending against the fleet of De Grasse and a strong land force at St. Christopher's. But, as De Grasse had landed eight thousand men, under De Bouill, and Hood had no land troops, he could not save the island. After its capture Rodney fell in with him, and their united fleet amounted to thirty-six ships of the line. It was well, for Hood informed Rodney that De Grasse was intending to join the Spanish general, Galvez, at St. Domingo, where they were to sail for a grand attack on the chief of the British West India Islands, Jamaica, almost the only island, excepting Barbadoes and Antigua, which Britain now owned in that part of the globe. On the 8th of April he was signalled that the French fleet was unmoored and proceeding to sea. Rodney instantly put out, and the next morning discovered this fleet under Dominica. The wind being in favour of De Grasse, he stood away for Guadeloupe; but Rodney gave chase, and Hood's squadron getting far in advance, De Grasse veered round in the hope of beating him before the rest of Rodney's fleet could come up. Hood received the fire of three men-of-war in the Barfleur, his ship, for some time; but he stood bravely to the enemy, and the wind now favouring Rodney, he came up and joined in the engagement. Several ships on each side were so much damaged that they were almost useless, and Captain Bayne, of the Alfred, was killed. The next morning the French were nearly out of sight; but Rodney pressed after them, for he knew that if they succeeded in joining the Spaniards, he should have sixty sail, instead of thirty-six, to contend with."Don't bring them into it," he implored. "If you will not come away, I will tell you now, Felipa, that I love you." He was more in earnest than Landor had been. She felt that herself. His voice broke, and he paled.

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

THREE:Besides succeeding to the government of a country whose chief province was thus exhausted, the finances of the Company were equally drained, both in Calcutta and at home, and the Directors were continually crying to Hastings for money, money, money! As one means of raising this money, they sent him a secret order to break one of their most solemn engagements with the native princes. When they bribed Meer Jaffier to depose his master, by offering to set him in his seat, and received in return the enormous sums mentioned for this elevation, they settled on Meer Jaffier and his descendants an annual income of thirty-two lacs of rupees, or three hundred and sixty thousand pounds. But Meer Jaffier was now dead, and his eldest son died during the[324] famine. The second son was made Nabob, a weak youth in a weak government, and as the Company saw that he could not help himself, they ordered Hastings to reduce the income to one-half. This was easily done; but this was not enough, disgraceful as it was. Mohammed Reza Khan, who had been appointed by the Company the Nabob's Minister, on the ground that he was not only a very able but a very honest man, they ordered to be arrested on pretended pleas of maladministration. He and all his family and partisans must be secured, but not in an open and abrupt way, which might alarm the province; they were to be inveigled down from Moorshedabad to Calcutta, on pretence of affairs of government, and there detained. Nuncomar, the Hindoo, who had been displaced, in order to set up Mohammed, who was a Mussulman, and who had been removed on the ground of being one of the most consummate rogues in India, was to be employed as evidence against Mohammed. Hastings fully carried out the orders of the secret committee of the India House. He had Mohammed seized in his bed, at midnight, by a battalion of sepoys; Shitab Roy, the Minister of Bahar, who acted under Mohammed at Patna, was also secured; and these two great officers and their chief agents were sent down to Calcutta under guard, and there put into what Hastings called "an easy confinement." In this confinement they lay many months, all which time Nuncomar was in full activity preparing the charges against them. Shitab Roy, like Mohammed, stood high in the estimation of his countrymen of both faiths; he had fought on the British side with signal bravery, and appears to have been a man of high honour and feeling. But these things weighed for nothing with Hastings or his masters in Leadenhall Street. He hoped to draw large sums of money from these men; but he was disappointed. Though he himself arranged the court that tried them, and brought up upwards of a hundred witnesses against them, no malpractice whatever could be proved against them, and they were acquitted. They were therefore honourably restored, the reader will think. By no means. Such were not the intentions of the Company or of Hastings. Whilst Mohammed and Shitab Roy had been in prison, Hastings had been up at Moorshedabad, had abolished the office of Minister in both Patna and Moorshedabad, removed all the government business to Calcutta, cut down the income of the young Nabob, Muharek-al-Dowla, to one half, according to his instructions, and reduced the Nabob himself to a mere puppet. He had transferred the whole government to Calcutta, with all the courts of justice, so that, writes Hastings, "the authority of the Company is fixed in this country without any possibility of competition, and beyond the power of any but themselves to shake it."Mr. M'Cleland, ditto 3,300
