TWO:Jeff! Dick knelt and lifted the mans head.

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:During this year little was done in America. General Bradstreet defeated a body of the enemy on the River Onondaga, and, on the other hand, the French took the two small forts of Ontario and Oswego.
  • 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:She was sitting in her room, sewing. Of late she had become domesticated, and she was fading under it. He had seen it already, and he saw it more plainly than ever just now. She looked up and smiled. Her smile had always been one of her greatest charms, because it was rare and very sweet. "Jack," she greeted him, "what have you done with the bread knife you took with you, dear? I have been lost without it."

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

THREE:"I wish you to read it, John," she said quietly.
  • 1 Recovery of the detergent solvent Recovery of the cleaning solvent such as electronic parts industry, precision instrument industry.
  • 2Solvent recovery and the refinement Solvent recovery and the refinement such as chemical industry, an industry of medical supplies, food industry, the fermentation industry.
THREE:And what he heard there made him come home, Sandy added.It might have been imagined that this magnificent and destructive repulse would have convinced the allies that the siege was hopeless, but they were pretty well informed that General Elliot had well nigh exhausted his ammunition in this prodigal death-shower, and they had still their great combined fleet, snug in the narrow bay, with scouts in the Strait to prevent the carrying in of supplies. But on the 24th of September news arrived at Madrid that the fleet of Lord Howe was under weigh for Gibraltar. Howe's fleet of thirty-four sail-of-the-line, six frigates, and three fire-ships, though in the neighbourhood of one of fifty sail-of-the-line, besides a number of frigates and smaller vessels, managed to get into the bay of Gibraltar all safe, amid the wildest acclamations of soldiers and inhabitants. By the 18th of October all the store-ships had discharged their cargoes, and had passed through the Strait, and on the 19th Lord Howe followed them with his fleet. The enemy's fleet then came out after him, and the next day they were in the open ocean, and Howe proceeded to their leeward to receive them. Some of their vessels had suffered[296] in the late gales, but they had still at least forty-four sail to Howe's thirty-four, and, having the weather-gauge, had every advantage. But after a partial firing, in which they received great damage from Howe, they hauled off and got into Cadiz bay. Howe, then dispatching part of his fleet to the West Indies and a second squadron to the Irish coast, returned home himself. The news of the grand defence of Gibraltar produced a wonderful rejoicing in England; thanks were voted by Parliament to the officers and privates of the brave garrison; General Elliot was invested with the Order of the Bath on the king's bastion in sight of the works which he had preserved, and on his return, in 1787, at the age of seventy, he was created a Peer as Lord Heathfield of Gibraltar.
