TWO:Down the middle of the Ganges a white bundle is being borne, and on it a crow pecking the body of a child wrapped in its winding-sheet.

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:I proposed to go in without the soldiers. Impossible, it was not etiquette! I was the Rajah's guest. The Prince of Morvi and I could not mingle with the crowd, our escort was necessary to isolate us. Well, then, the soldiers must take off their shoes, and leave their belts and guns at the door! Again impossible. Where would the prestige of the uniform be?I rode to Tiger Hill. Overhead hung a dense mist, like a roof of shadow, perfectly still, wrapping us in damp and frightfully cold vapour. After two hours' ride in the darkness we reached our [Pg 151]destination. Suddenly the cloud fell like a curtain pulled down, the sky appeared, and then the earth at our feet became visible in the starlight. Some vestiges of a temple could be discerned among the grassthe foundations of enormous halls, and still standing in solitude, the brick chimneys in which the devout were wont to burn their prayers, written on rice-paper. Far away, in the transparent air, above a wall of grey cloudthe dull, dingy grey of dirty cotton-woola speck showed as a beacon of lilac light, of the hue and form of a cyclamen flower; this turned to rose, to brick-red, to warm gold colour, fading into silver; and then, against the blue sky, showed immaculately white. This was GaurisankarMount Everestthe top of the world, appallingly high, inconceivably vast, though lost in the distance, and seen from a hillock three thousand metres above the sea.
  • 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:

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

THREE:On our way back to the hotel, in a park through which we had to pass, we suddenly heard overhead a shrill outcry proceeding from a banyan tree to which a number of vampires had hung themselves up. Clinging together side by side, like black rags, and hardly visible in the thick foliage, the creatures formed a sort of living bunch, creeping, swaying, and all uttering the same harsh, monotonous, incessant cry.A poor sick ape, beaten by all the others, sat crying with hunger at the top of a parapet. I called her for a long time, showing her some maize on a tray. At last she made up her mind to come down. With the utmost caution she reached me, and then, after two or three feints, she struck the platter with her closed fist, sending all the grain flying. Utterly scared, she fled, followed to her perch by a whole party of miscreants roused by the gong-like blow on the tray. Others stole into the temple to snatch the flowers while the attendant priest had his back turned; and when I left they were all busily engaged in rolling an earthenware bowl about, ending its career in a smash. In front of the temple the crimson dust round a stake shows the spot where every day the blood is shed of a goat sacrificed to the Divinity.
  • 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:Women porters came on foot, hidden under bales, nets full of crocks, faggots, and trusses of hay.[Pg 248] Children, and women in sareesfine ladieshad nothing to carry; some were wrapped in yashmacks, shrouding them from head to foot with a little veil of transparent muslin over their eyes.
