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:"Nothing much," he told her. He and Taylor could take care of the talking. Her part would be just to stand by and pay attention.
  • 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.

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

THREE:Those Highlanders commenced their march into England with no predilection for the adventure. The warfare of Scotland was familiar to them; in all ages they had been accustomed to descend from their mountains and make raids in the Lowlands. But England was to them an unknown region; they knew little of the dangers or the perils before them; they knew that in the Whiggish clans of the West they left powerful enemies behind them. No sooner did they lose sight of Edinburgh than they began to desert. Charles led his division of the army across the Tweed at Kelso, and sent on orders to Wooler to[100] prepare for his reception, thus keeping up the feint of marching eastward; instead of which, he took his way down Liddesdale, and on the 8th of November crossed the Esk, and encamped that night at a place called Reddings, on the Cumberland side.

THREE:On the 28th of September the combined army of French and Americans came in sight of York Town, and encamped about two miles from the outworks. The next morning they extended themselves towards the left of Cornwallis, but cautiously; and the English pickets slowly retired within the outer lines at their approach. That evening Cornwallis received a despatch from Sir Henry Clinton, dated September 24th, which gave the cheering expectation that he was duly sensible of the imminence of the danger, and of his responsibility. He said:"At a meeting of the general and flag officers held this day, it is determined that above five thousand men, rank and file, shall be embarked on board the king's ships, and the joint exertions of the navy and army made in a few days to relieve you, and afterwards to co-operate with you. The fleet consists of twenty-three sail of the line, three of which are three-deckers. There is every reason to hope that we start on the 5th of October." On this promising intimation of speedy aid, Cornwallis immediately drew in his small force from the extended outworks, and concentrated them within the entrenchments round the town. Undoubtedly it was a measure calculated to save much life, which must have been lost in defending outworks too widely extended for the enclosed force; but it encouraged the Americans, who did not expect to gain them thus easily. Two thousand men took up their ground before Gloucester. Round York Town itself Washington, Rochambeau, Lafayette, and St. Simon concentrated their forces. On the night of the 1st of October, the French on the right and the Americans on the left drew nearer, and commenced breaking ground. Six days were then spent in bringing from the ships fifty pieces of cannon, some of them very heavy, ammunition, and other military stores; in fact, as much preparation was made for carrying this single post as if it had been a regular and first-rate fortress. On the night of the 6th of October the French and Americans began casting up their first parallel within six hundred yards of Cornwallis's lines. By the 9th of October their trenches and batteries were completed, and that afternoon they opened a tremendous fire on the town. Cornwallis replied to them with vigour,[283] but he found many of his guns on the left silenced, and his works greatly damaged. On the night of the 11th the enemy began their second parallel within three hundred yards of the lines. In its progress, for three days, Cornwallis committed much havoc amongst them by opening fresh embrasures for guns, and pouring an incessant shower upon them of balls and shells. Two redoubts on the left flank of the British more particularly annoyed them, and Washington determined to carry these by storm. Of course they were carried, and their guns then turned on York Town.
