TWO:One of the police in charge had a whip, and when he was leading away the old man, holding his chain he "played horses" with him, to the great amusement of the bystanders, and even of the old fellow himself.Children were selling whortleberries in plaited baskets; they came up very shyly, and as soon as they had sold their spoil hurried back to hide in their nook. Further on a little Afghan boy, standing alone and motionless by the roadside, held out three eggs for sale.

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:Very early in the morning we met a many-coloured caravan of men, women, and children riding astride on asses, amid baskets and bundles. They were on their way to a wedding: they had stopped to rest for the last time; and alone, far from the merry, noisy group, a "bad woman" sat down on a stone. She was on the way to the same festival, and was allowed to travel with the[Pg 288] caravan for succour in case of need; but she was not permitted to join the party.Halting at noon at Kohala, we found a barber in the open street shaving and snipping his customers. In a cage hanging to the bough of a tree above his head a partridge was hopping aboutblack speckled with white, and gold-coloured wings. It had a strident cry like the setting of a saw.
  • 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:First went six armed regulars, then a party on horseback, for the most part Persians, one of whom was carrying in his arms an enormous sheaf of roses, which hid him completely and drooped over the saddle.
  • 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:When I went away home to the fort, where I was living with my friend Lieutenant F, the sentinel's challenge, the tall grey walls casting sharp shadows on the courtyard silvered with moonlight, and another sentry's cry; and still, in contrast with the cheerful evening, I could remember nothing but the tonga post-horsea thing so frequent in this land of fanatics, so common that no one gives it more than a passing thought.
