TWO:In the heart of Girgaum, one of the suburbs of Bombay, at the end of a street, under a large areca palm an old man was selling grain and rice in open baskets. A whole flight of bickering sparrows settled on his merchandise, and he looked at them with happy good humour without scaring them away.

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:At the end of a passage that runs round the temple an old woman who had just been bathing was changing her wet saree for a dry one, and appeared quite stripped, dropping her garments, and careful only not to let her face be seen.The sultan's bath is lined with panels of lapis lazuli framed in gold, and inlaid with [Pg 210]mother-of-pearl, or looking-glass, and the walls have little hollow niches for lamps, over which the water fell in a shower into a bath with a decoration of scroll-work. And in front of Jehangir's room, again a series of basins hollowed in the steps of a broad marble stair, where a stream of water fell from one to another.
  • 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:Inside the mausoleum numberless lustres hang from the roof, and fine large standing lamps with crystal pendants burn round two tombs covered with antique hangings and wreathed with jasmine; beneath these lie the two last kings of Oudh. Small models of two famous mosques, one in gold and one in silver, are placed on the tombs, round which a whole regiment of obsequious moollahs and beggars mount guard. On the walls childish paintings, representing scenes of the Anglo-Indian conflict, alternate with mirrors in gilt frames, and silk standards exquisitely faded, embroidered with dim gold and silver, and surmounted by tridents.At Roza, the plateau above the Hindoo sanctuaries, above a dozen of Moslem mausoleums are to be seen under the spreading banyans that shelter them beneath their shade, and sometimes hide them completely; the white objects are in a whimsical style of architecture, hewn into strange shapes, which in the doubtful starlight might be taken for ruins.

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

THREE:Huge vultures were prowling about the place.[Pg 222] At our approach they flapped a little away, and then perching on a heap of stones preened their feathers with clumsy, ungraceful movements.
  • 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 224]Behind this mosque, by narrow alleys hung with airy green silk that had just been dyed and spread to dry in the sun, we made our way to the mausoleum of Badorgi Shah: a cloister, an arcade of octagonal columns carved with flowers, and in the court, the tombs of white stone, covered with [Pg 64]inscriptions, that look like arabesques. There are some children's tombs, too, quite small, in finer and even whiter stone, and two tiny stones under which lie Badorgi's parrot and cat.
