TWO:Then the dancing began again, interrupted for a minute by the call of the night-watchman as he went past carrying a long bamboo. He paused for a moment to watch the performance, and then was lost in the darkness.

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:
  • 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:In the prince's stables were a long row of brood mares and superb stallions; and then a hundred or so of colts were turned out into the yardmischievous, frisking things, romping against each other, suddenly stopping short, and wrapped ere long in white dust, which fell on us, too.Then a girl's body was brought out, wrapped in white muslin; the bier, made of bamboo, was wreathed with marigolds, and on the light shroud there were patches of crimson powder, almost violet. The bearers, on reaching the river, placed the body in the water, leaving it there for a time.

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

THREE:Coolies in white turbans were busy round the machines. They are very skilful, but work with determined slowness as a mute rebellion against the humiliating coercion of obeying a thing of wood and iron, and above all of obeying it without stopping, for the ideal of every Hindoo is to do nothing. And this rose to positive martyrdom when, in the absence of our own servants, who were nowhere to be found, one of these craftsmen, a Brahmin, strictly forbidden by his religion ever to touch the food of the disbelievers, or even the[Pg 294] vessels they use, was obliged to make tea for us. Looking utterly miserable, the poor fellow weighed out the leaves, put them into little antique earthenware pots, and poured on the boiling water. A sand-glass marked how long the infusion was to stand. He even brought us some pretty little crackle basins that looked as if they had come out of some old-world convent pharmacy; but the poor man could not bring himself to pour the tea outhe fled.In one brilliantly-lighted hall, priests, dressed in long yellow dalmatics, were adoring idols, elephants, Anantas; and from an enormous gold lotus sprang the Mandeel, rising through the dome, its tip standing in the outer air to bear the white flag that is hoisted on high festivals. At the entrance to this shrine parrots in cages suddenly set up a hostile outcry as I passed them, and were only pacified by the coming of a priest, who gave them some food. The clatter, however, had attracted other Brahmins; one of them desired me to leave, "and[Pg 117] at once." I declined to obey, so he sent for the elephant who does duty as police, to turn me out.
  • 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:[Pg 270]As we stood up there the caravan for Cabul came in sight on the road below, and slowly disappeared wrapped in dust, with mechanical steadiness and[Pg 250] without a sound. After that came the other train of travellers from Peshawur, singing to the accompaniment of mule-bells, every sound swelled by the echo. Children's laughter came up to our ears, the scream of an elephant angry at being stoppedeven at a distance we could still hear them a littleand then silence fell again under the flight of the eagles soaring in circles further and further away as they followed the caravan.
