TWO:The morning mist shrouds everything; the scene insensibly passes through a series of pale tints, to reappear ere long in the clear rosy light, which sheds a powdering of glowing gold on the broad roadstead of Bombay."Fivesix," said the baboo, hesitating; then,[Pg 194] seeing that I was quite incredulous, "Sometimes more," he added.

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 Jan the pagodas are of red stone. The largest, conical in shape, covers with its ponderous roof, overloaded with sculptured figures of gods and animals, a very small passage, at the end of which two lights burning hardly reveal a white idol standing amid a perfect carpet of flowers. Round the sacred tank that lies at the base of the[Pg 45] temple, full of stagnant greenish-white water, are flights of steps in purple-hued stone; at the angles, twelve little conical kiosks, also of red stone and highly decorated, shelter twelve similar idols, but black. And between the temples, among the few huts that compose the village of Jan, stand Moslem mausoleums and tombs. Verses from the Koran are carved on the stones, now scarcelyl visible amid the spreading briars and garlands of creepers hanging from the tall trees that are pushing their roots between the flagstones that cover the dead.
  • 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:Close to a field that had just been reaped four oxen yoked abreast were threshing out the grain, tramping round and round on a large sheet spread on the ground. The driver chanted a shrill, slow tune; further away women in red were gleaning, and a patriarch contemplated his estate, enthroned on a cart in a halo of sunset gold.

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

THREE:Little beggar-girls with a depraved look, artful little hussies, pursued us coaxingly: "Give something, sahib, to pretty Cingalee girl, who wants to go over sea to where the gentlemens live."
  • 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.
