TWO:She did not return to the ramada, but before long her husband came in search of her.

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:If Cairness had not slipped and gone sprawling down[Pg 232] at that moment, the fourth bullet would have brought him up short. It sung over him, instead, and splashed against a stone, and when he got to his feet again the eyes had come out from their hiding-place. They were in the head of a very young buck. He had sprung to the top of his rock and was dancing about with defiant hilarity, waving his hands and the Winchester, and grimacing tantalizingly. "Yaw! ya!" he screeched. Cairness discharged his revolver, but the boy whooped once more and was down, dodging around the stone. Cairness dodged after him, wrath in his heart and also a vow to switch the little devil when he should get him. But he did not seem to be getting him.He went and stood beside her and laid his hand upon her hair.
  • 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:Chapter 24Food, ice-drip trays and vegetables in their dry-air receptacles, were all they discovered by a painstaking search. A glance into the hydrator packed with vegetables, crisp lettuce, long endive, and other varieties, a foray behind and under everything satisfied them that another clue had gone Westand left them very much out of favor.

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

THREE:The spirit of Choiseul having departed from the French administration, and the king having so unequivocally expressed his intention not to go to war, the Spanish Court hastened to lower its tone and offer conciliatory terms. In December they had proposed, through Prince de Masserano, to disavow the expedition of Buccarelli, if the English Court would disown the menaces of Captain Hunt. This was promptly refused, and orders were sent to Mr. Harris to quit the capital of Spain. He set out in January, 1771, but was speedily recalled; the expedition of Buccarelli was disavowed; the settlement of Port Egmont was conceded, whilst the main question as to the right of either party to the Falklands at large was left to future discussion. So little value, however, did Britain attach to the Falkland Isles, that it abandoned them voluntarily two years afterwards. For many years they were forsaken by both nations; but in 1826 the Republic of Buenos Ayres adopted them as a penal colony, and in 1833 the British finally took possession of them.[See larger version]
