TWO:The muddy waters reflected the grey houses and the roofs of unbaked clay, on which the winter snows were melting in black trickling drops.And again ruins. Under an archway still left standing on piers carved with lilies and foliage, lay a whole family of pariahs covered with leprosy and sores.

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:Below one of the palaces is a huge statue of Vishnu Bhin in a reclining attitude, daubed with ochre, the face flesh-colour and white; a statue which is carried away every year by the floods and restored every year in its pristine grossness.In a consecrated hall we came to a plaster image of a camel modelled over stone. To prove that you are without sin you must be able to pass under the beast, or at least between the front legs and the girth of the belly without touching any part; and so very narrow is this little gateway of Ja?n virtue that, to preserve my character in the presence of my escort, I did not attempt it.
  • 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:
  • 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:Past the buildings, and palaces with gardens enclosed behind pierced stonework, and then across fresh green fields full of flowers, under the shade of banyans and palm trees, we reached the temple of the monkeys. This temple, dedicated to the fierce and bloodthirsty goddess Durga, is painted all over of a vivid red colour, blazing in the sunshine with intolerable brightness. Inside the sanctuary a black image of the goddess may be seen, mounted on her lion, and flowers are arranged about her in radiating lines mingled with gold thread, and producing very much the effect of a theatrical sun. In the [Pg 162]forecourt, on the carvings and the roof of the temple monkeys swarm, rushing after each other, fighting for the grains of maize that are thrown to them, and tormenting the wretched mangy dogs that seek refuge in the temple precincts, where they, too, are kept alive by the faithful.The gardens are overgrown with exuberant tropical vegetation: orchids, daturas hung with their scented purple bells, gardenias and creepers; and yet what the brother of a London friend, on whom I am calling, shows me with the greatest pride, are a few precious geraniums, two real violets, and a tiny patch of thickly-grown lawn of emerald hue.
