TWO:Next day was kept as the spring festival. Every man had a rose stuck into his turban, and a shirt embroidered in gold on the shoulders and breast. The women appeared in stiff and gaudy veil cloths, bedizened with trumpery jewellery. Everybody was gay; a little excited towards evening by arrack, and dancing, and singing to the eternal tom-toms. Even the fiercest men from the hills, with black[Pg 279] turbans and enormously full calico trousers that once were white, and shirts embroidered in bright silks, had set aside their ferocious looks and stuck roses in their pugarees, smiling at those they met.

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:Close to a village that has sprouted under the baobab-trees, in the midst of the plain that once was Khoutab, in the court of a mosque, is the marble sarcophagus of a princess. Grass is growing in the hollow of the stone that covers her, in fulfilment of the wishes of the maiden, who in her humility desired that when she was dead she should be laid to rest under the common earth whence the grass grows in the spring. And not far from the rajah's daughter, under a broad tamarind tree, in the blue shade, is the tomb of Kushru, the poet who immortalized Bagh-o-Bahar. On the sarcophagus, in the little kiosk, was a kerchief of silk and gold, with a wreath of fresh flowers renewed every day by the faithful.
  • 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:All round the sanctuary, in niches under a square cloister, are three hundred and fifty alabaster Buddhas, all alike, with the same jewel in their forehead, and on their shoulders and round their bodies[Pg 61] gold bands set with imitation gems and cut glass. An old woman, who had come thither at daybreak, had prayed to each of these Buddhas; to each she had offered up the same brief petition, she had struck the three bells on her way, and she was now in the sanctuary, calling out a prayer while beating a gong that hangs from the arch. Meanwhile other worshippers were murmuring their invocations prostrate before the jewelled Buddha.

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

THREE:
  • 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:The want of foresight in the people here is amazing. A servant earning five rupees a month got his son married, a child of fifteen, and for this event he bought fireworks on credit, and at enormous interest, which would cost him three years' wages.
