TWO:From Kusshalgar we were travelling in a tonga once more. The landscape was all of steep hills without vegetation; stretches of sand, hills of claylilac or rosy brick-earth scorched in the sun, green or brown earth where there had been recent landslips, baked by the summer heat to every shade of red. There was one hill higher than the rest, of a velvety rose-colour with very gentle undulations, and then a river-bed full of snowy-white sand, which was salt.

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:In the evening, as I again went past the Towers of Silence, the palm trees were once more crowded with sleeping birds gorged with all the food sent them by the plague. On the other side of Back Bay, above the Field of Burning, a thick column of smoke rose up, red in the last beams of the crimson sun.
  • 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:The almost imperceptible hum of a bagpipe came up from below; in a white mosque of open colonnades enclosing a paved court, and in front of the little lamps that burned above the holy of holies sheltering the Koran, figures in light garments were prostrate in prayer; their murmurs came up to us in sighs, mingling with the slow and tender notes of the music.In one tent there was a display of innumerable gilt images, very suggestive of Jesuit influencemincing, chubby angels, martyrs carrying palm-branches, and ecstatic virgins with clasped hands, all serving to decorate the shrine in which the god was to be carried back to the temple. Coloured fires lighted the workmen, and in the background the temple was darkly visible, with only a few dim lamps shrouded in incense, and burning before Rama, whose festival was being kept.
  • 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:To light the way, coolies carried long iron tridents tipped with balls of tow soaked in oil. The mass moved slowly forward through the people, suddenly soothed to silence. The procession paused at the wayside altars, and then, in the middle of a circle formed by the torch-bearers and coloured lights, the sacred bayadres appearedthree girls with bare heads, dressed in stiff new sarongs heavy with tinkling trinkets, and an old woman crowned with a sort of very tall cylindrical tiara of red velvet embroidered with gold. Very sweet-toned bagpipes and some darboukhas played a slow tune, and the dancers began to move; they spun slowly round, their arms held out, their bodies kept rigid, [Pg 137]excepting when they bowed to the shrine. The crude light of the red fire or the sulphurous flare of the torches fell on their glittering ornaments, alternately festive and mysterious, shedding over the performance an atmosphere at once dreamy and magically gorgeous.

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
