TWO:These gentlemen of the Civil Service would put in an appearance "now and then"the eternal "now and then" that answers every question in India. They stepped out of a buggy, walked quickly round, had seen, and were gone again in a great hurry to finish some important work for the next European mail.

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 the garden are the bird sellers, their little cages packed full of parrots, minahs, and bulbuls; and tiny finches, scarcely larger than butterflies, hang on the boughs of ebony trees and daturas in bloom.
  • 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:Further on we came to a courtyard surrounded by a cloister, where the market for precious stones was held. The empress, invisible under her wrappers of gauze as thin as air, and surrounded by her women fanning her, would come out on her high balcony to choose the gems that pleased her for a moment by their sparkle, and then disappear into the gardens behind insurmountable walls. In another court, a[Pg 209] pool kept stocked with fish gave Shah Jehangir the pleasure of fancying he was fishing.MADRAS

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

THREE:There are temples all along the shore, poor little structures for the most part. On the walls gaudy borders of crude colour serve to frame chromo-lithographs representing the principal events of the Vedas. There are but one or two sanctuaries built of marble, and very rarely have the idols any precious 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:In the distance we heard a sound of pipes, and the merchant hastened out to call the nautch-girls, who began to dance in the street just below us, among the vehicles and foot-passengers. There were two of them; one in a black skirt spangled with silver trinkets, the other in orange and red with a head-dress and necklace of jasmine. They danced with a gliding step, and then drew themselves up with a sudden jerk that made all their frippery tinkle. Then the girl in black, laying her right hand on her breast, stood still, with only a measured swaying movement of her whole body, while the dancer in yellow circled round, spinning as she went. Next the black one performed a sort of goose-step with her feet on one spot, yelling a so-called tune, and clacking her anklets one against the other. Then, after a few high leaps that set her saree flying, the dance was ended; she drew a black veil over her head, and turned with her face to the wall. The other boldly asked for backsheesh, held up her hands, and after getting her money, begged for cakes and sugar.
