TWO:In a little alley of booths was a shop with no front show, and behind it a sort of studio full of carvers and artists working on sandal-wood boxes, ivory fans as fine as gauze, and wooden lattices with elaborate flower patterns, used to screen the zenana windows. And in little recesses workmen dressed in white, with small copper pots about them in which they had brought rice for their meals, were chasing and embossing metal with little taps of their primitive tools, never making a mistake, working as their fancy might suggest, without any pattern, and quite at home in the maze of interlacing ornament.

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:On entering the park the cocked turbans of the bodyguard again reminded us of the hats of the French Guards.
  • 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:A golden mass, an enormous shrine chased all over and starred with tapers, now came forward, borne by a score of naked men. Against the gold background, in a perfect glory of diamonds and pearls, sat Vishnu, decked out with flowers and jewels, his head bare with a huge brilliant in his forehead.

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:A delightful surprise was a museum of Indian art, the first I had seen, a fine collection and admirably arranged;[A] but the natives who resorted hither to enjoy the cool shelter of the galleries talked to each other from a distance, as is their universal custom, at the top of their voices, which rang doubly loud under the echoing vaults.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.
