TWO: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.

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:There, again, they all sit down in the garden. The same little packets of betel, only wrapped in gold leaf, are offered to the company, and bunches of chrysanthemum sprinkled with scent.Behind a ponderous wall, dinted all over by shot, and showing broad, light patches once covered by earthenware tiles, is the palace of Runjeet Singh, inlaid with enamelled pictures in green, blue, and yellow of tiger-fights and horse-races, mingling with flowers and garlands of boughs. The durbar, the hall or presence chamber, opens by a verandah on a forecourt paved with marble; in its walls are mirrors and panels of coloured glass over a ground of dull gold, agate-like tints iridescent with a nacreous, silvery, luminous lustre.
  • 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:Asses followed, oxen and more camels, loaded beyond their strength with old iron, tin pannikins, a whole cargo of goods in cases from Manchester and Sheffieldso badly packed that things came clattering down as the beasts pushed each other amid oaths and blows.

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

THREE:The ancient palace of the kings of Lahore. Amid the ruins there is a mosque of red stone flowered[Pg 236] with white marble, the cupola of a material so milky that it might be jade; and the structure is mirrored in a pool of clear water, dappled with sun-sparks over the rose-coloured stones at the bottom.
  • 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:Outside the palace is a large garden, devoid of shade, with pools of water bowered in flowers and shrubs that shelter myriads of singing birds. At the end of the park is a tank full of crocodiles. A keeper called the brutes, and they came up facing us in a row, their jaws open to catch the food which the Rajah amuses himself by throwing to them.Beyond this point among the mountains the road seemed to vanish, to lead nowhere, lost in pale red among the red cliffs, as if it stopped at the foot of the rocky wall.

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