TWO:Before the Clockwork man had time to reply to this embarrassing question, the curtain was again swiftly drawn, and an anxious female face appeared. "James, has the conjurerOh, yes, I see he has. Do be quick, James. The picture is nearly over.""No, I do not like him. Do you?"

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:It was cold that night in the upper air, and there was a strong wind blowing that chilled our young friends to the bone. The sleeping accommodations were not of the best, as there were no beds, and they had nothing but the rugs and shawls they had brought along from the foot of the mountain. Fred asked if there was any danger of their being[Pg 212] disturbed by tigers or snakes, and was speedily reassured by Frank, who thought that any well-educated beast or serpent would never undertake a pilgrimage to the top of Fusiyama; and if one should have strayed as far as their resting-place, he would be too much played out to attend to any business. But though large game did not abound, there was plenty of a smaller kind, as they found before they had been ten minutes in the huts. Previous visitors had left a large and well-selected assortment of fleas, for which they had no further use, and their activity indicated that they had been for some time without food. They made things lively for the strangers, and what with chilling winds, hard beds, cramped quarters, and the voracity of the permanent inhabitants of the place, there was little sleep in that hut during the time of their stay.
  • 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:

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

THREE:"We saw a good many temples, and went through some of them, but, on the whole, they were rather disappointing, as they were not so fine as those at Pekin, and far behind those of Japan. The most interesting of the pagodas is the one known as the 'Five-storied Pagoda,' so called because[Pg 412] it is five stories high. It stands on a hill that overlooks the whole city on one side, and a large cemetery on the other; and when you have climbed to the top, the view is very fine. The roofs of the houses are of all shapes and kinds, and the streets are so narrow that you can see very few of them as you look down from the top of the pagoda. On the one hand you have a densely peopled city of the living, and on the other an equally densely peopled city of the dead. Our guide said the cemetery had more inhabitants than the city; and when we asked him how many people lived there, he said 'Many millions.' You have to come to China to learn that the people in a cemetery are supposed to live there.
  • 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:

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
