TWO: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.The doors were shut; all was silencethe stillness of the star-lit night.

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:The Prince of Morvi came before sunrise to take us to the temples of Satrunji. On the way we outstripped carts packed full of women and children in light shimmering muslins. They were all making a pilgrimage to the sacred hill, singing shrill chants in time to the jolting of their springless vehicles,[Pg 70] and broken by oaths and imprecations at the stoppages occasioned by our expedition.Trees shut in the flat, interminable road, and it was midnight before we reached Srinagar, where I found, as a surprise, a comfortable house-boat with inlaid panels, and a fragrant fire of mango-wood smelling of orris-root.
  • 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:Then a fat native lawyer began to speak, and silence fell on the crowd of three or four hundred listeners sitting behind the accused, as if they were in church. The monotonous voice went on and on, urging every plea.
  • 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:And then night, the real night, transparently blue and luminous with stars, appeared above the last cloud that vanished with the last clap of thunder. Unspeakable freshness and peace reigned over nature, and in the limpid air the mountain-chains, the giant Himalayas, extended to infinity in tones of amethyst and sapphire. Nearer to us, lights sparkled out in the innumerable huts built even to the verge of the eternal snows, on every spot of arable ground or half-starved grass land.As soon as dessert was removed two lieutenants got up, and seizing a couple of drums played away with all their might, while some other officers, under the pretext of dancing a Highland fling, cut the most amazing capers. When the band had left[Pg 276] the fun went on to the sound of the banjo, lasting late into the cool night, all in the highest spirits.
