TWO:And the figures go down after long discussions, till at last the question as to whether I know the worth of pashmina begins all over againendless.

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:The highest peak of the chain that overlooks Bunnoo looks like the ruins of a fortress. A legend, which must have had its origin at some time when a man-eating tiger lurked in the neighbourhood, relates that it is the lair of a ferocious ogre always on the look-out for prey. Nothing on earth would induce any of the natives to go up the mountain; nay, for a long distance even the plain is not too safe.
  • 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:When we stopped to change horses, two or three mud-huts under the shade of a few palm trees would emit an escort of little native boys, who followed the fresh team, staring at the carriage and the "Inglis Sahib" with a gaze of rapturous stupefaction.A rosy light flooded the whole scene with fiery radiance, and then suddenly, with no twilight, darkness blotted out the shape of things, drowning all in purple haze; and there, where India had vanished, a white mist rose from the ocean that mirrored the stars.

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

THREE:The muddy waters reflected the grey houses and the roofs of unbaked clay, on which the winter snows were melting in black trickling drops.
  • 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:The want of foresight in the people here is amazing. A servant earning five rupees a month got his son married, a child of fifteen, and for this event he bought fireworks on credit, and at enormous interest, which would cost him three years' wages.Steaming over the transparent and intensely blue sea, we presently perceived an opaquer streak of sandy matter, getting denser, and becoming at last liquid, extremely liquid, yellow mudthe waters of the Ganges, long before land was in sight. Between the low banks, with their inconspicuous vegetation, a desolate shore, we could have fancied we were still at sea when we had already reached the mouth of the sacred stream. Some Hindoos on board drew up the water in pails to wash their hands and face, fixing their eyes in adoration on the thick sandy fluid. Enormous steamships crossed our bows, and in the distance, like a flock of Ibis, skimmed a whole flotilla of boats with broad red sails, through which the low sun was shining. The banks closed in, the landscape grew more definitetall palm trees, plots of garden ground, factory chimneys, a high tower. On the water was an inextricable confusion of canoes and row-boats flitting among the steamships and sailing barks moored all along the town that stretched away out of sight.
