TWO:Then some men go past who have a stick like a distaff thrust through their belt with a net wound round it; they net as they walk, heedless of jostling, their eyes fixed on their work.BOMBAY

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:After the giant a whole chain of lavender and rose-coloured peaks turning to blue came into sight in the marvellously clear atmosphere; then the sun rose below us, in the throbbing tide of heat the mountains seemed to come closer to us, but immediately the mist gathered about Gaurisankar. "The Apsaras wearing impenetrable veils, that mortals may not gaze too long on the throne of the gods,"[Pg 152] said my sa?s, who had fallen on his face since the first appearance of the snow-crowned colossus, with hands upraised towards the paradise of Indra.A humble poet, more venerated than the kings whose superb mausoleums are crumbling to dust in subjugated India, who, though she forgets her past, is still true to her dreams.
  • 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 left he was in a coppersmith's shop, singing with wide open, staring eyes; his face had a strangely sad expression while he sang a gay, jigging tune to foolish words that made the people laugh.

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

  • 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:In a quiet, darkened corner a girl was lying on a bier, a girl of the Brahmin caste, all in white, veiled by a transparent saree. By her side an old man, a bearded patriarch, seemed to wait for someone. Then another Brahmin came out from a little house, carrying the fire wherewith to light the funeral pile in a little pot hanging from his girdle. The two old men took up their burthenso light that even to them, tottering already towards their end, it seemed to be no weight. They made their way cautiously, so as not to tread on the [Pg 305]sleeping figures strewn about the street, going very slowly in devious zigzags. A dog woke and howled at them; and then, as silence fell, I could hear again the dying sounds of harmoniums and tom-toms, and the clatter of the games.The road lay among flowers, all-pervading; in the fields, on the rocks, on the road itself, pink flowers or lavender or white; bright moss, shrubs and trees in full bloom, and hovering over them birds of changing hue and golden butterflies.
