TWO:"We give rice to the sick, who all have dysentery, instead of the daily cake."The old woman's bones and ashes were cast into the Ganges, her husband still vacantly looking on, as all that was left of his life's companion floated for a few moments, and then was swallowed up in an eddy.

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:A man in the fort always struck out the hours on a gong, very slowly, in the heat of the day. Twelve at noon was interminableone, two, three were so feeble as to be scarcely audible. And then when it was cooler and the tom-toms could be heard in the distance, the strokes had a queer dislocated rhythm, and sometimes even a stroke too many, smothered in a hurried roll.The people came back to the dancing, which went on till daylight. The music could be heard in the distance, drowned from time to time by the yelling of the jackals or the watchman's call, and it was not till daybreak that the drumming ceased.
  • 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 artist sat at work in a corner of the window, copying minutely, for the thousandth time perhaps, a Taj or a Moti Musjid. Quite unmoved while his[Pg 226] shopman displayed his wares, he worked on with brushes as fine as needles; but when, on leaving, I asked him where I could procure some colours I needed, "Then the sahib paints?" said he; and he rose at once, insisted on my taking a seat, pressed me to accept a little sandal-wood frame, as a fellow-artist, and then would positively paint my portrait.
  • 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:The country was nowhere deserted. Labourers in the rice-fields were transplanting the young seedlings or watering the taller growth that waved in delicate transparent verdure. Or again, there were the watchers perched on their platforms in the middle of the fields; fishermen pushing little nets before them, fastened to triangular frames, or grubbing in the mud in search of shell-fishsmall freshwater mussels, which they carried away in clay jars of Etruscan form. A motley crowd, with animated and graceful gesticulations; the women red or white figures in fluttering sarees, with flowers in their hair, and a few glittering bangles on their arms; the children quite naked, with bead necklaces and queer charms of lead or wood in their ears or their nose; the men slender and active, wearing light-coloured turbans made of yards on yards of twisted muslin, their brown skin hidden only by the langouti or loin-cloth.
