TWO:Abibulla saw them off with great deference and a contrite air, and watched their retreat; then, as[Pg 260] I was about to send him to despatch the message, he was indignant. The police! What could they do to a sahib like me? It was all very well to frighten poor folksit was a sin to waste money in asking for a reply which I should never be called upon to showand so he went on, till I made up my mind to think no more of the matter. And whenever I met the chief at the bazaar or by the Jellum, he only asked after my health and my amusements.

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:And, quite unexpectedly, as we turned a corner beyond the coppersmiths' alley, we came on a row of tea-shops, displaying huge and burly china jars. Chinamen, in black or blue, sat at the shop doors in wide, stiff armchairs, their fine, plaited pigtail hanging over the back, while they awaited a customer with a good-humoured expression of dull indifference.
  • 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 front of the palace, beds filled with common plants familiar in every European garden fill the place of honour; they are very rare, no doubt, in[Pg 54] these latitudes, and surprising amid the gorgeous hedges of wild bougainvillea that enclose the park.

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

THREE:In the English quarter of Bombay the houses are European: Government House, the post office, the municipal buildingsperfect palaces surrounded by gardens; and close by, straw sheds sheltering buffaloes, or tents squatted down on common land; and beyond the paved walks are beaten earth and huge heaps of filth, over which hover the birds of prey and the crows.A Sikh, an old soldier, not long since bought a few acres of land; to pay for it he produced 800[Pg 281] rupees in silver, and on his wives, whom he brought with him, were 3000 rupees' worth of jewels.
  • 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:A very large temple, with its walls pierced in Persian patterns, contains fifty-two chapels behind pointed arches. In each chapel are four gods, all alike, of white plaster, all decked with the same jewels. In an angle of the vaulting a female figure, carved in the stone and wearing a tiara, holds an infant in her arms; this statue, with its long face and the rigid folds of the drapery, might have been transferred here from a gothic building.

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
