TWO:Squeezed in and crushed between houses that tower above it, rises the pointed dome of Biseshwar Matti, covered with leaves of chased gold; smaller cones surround the principal dome, bristling with tiny pyramids of gold, carved into flowers round statues of Kali with her eight arms, of Ganesa, and of peacocks with spread tails. Under this splendid cupola, dazzlingly bright against the sky,[Pg 156] the temple itself is quite small, and strictly closed against the unbeliever. Some pious hands had hung chains of jasmine and roses above the entrance, and they gave a touch of beauty to the stonework, very old, and soiled with large stains of oil. A sense of intense piety hangs about this sanctuary, subdues every voice, and bends the head of every passer-by in reverence of the mystery, and they all bring flowers.

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:"But rice is very good, and it is very dear, and some of them have been ill for three weeks."
  • 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:When the road was made through Bunnoo a pile of stones was heaped up in the middle of the village. The Moslems finally persuaded themselves that this was a saint's grave; and they come hither to perform their devotions, planting round it bamboo flagstaffs with pennons, and adding to the mound the stones they piously bring to it day by day.

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:

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