TWO:A causeway of white stone, with a fragile [Pg 234]balustrade and columns bearing lanterns of gold, leads from the shore to the temple.

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:Abibulla saw them off with great deference and a contrite air, and watched their retreat; then, as[Pg 260] I was about to send him to despatch the message, he was indignant. The police! What could they do to a sahib like me? It was all very well to frighten poor folksit was a sin to waste money in asking for a reply which I should never be called upon to showand so he went on, till I made up my mind to think no more of the matter. And whenever I met the chief at the bazaar or by the Jellum, he only asked after my health and my amusements.All round the post-office there is invariably a crowd of natives scribbling in pencil on post-cards held in their left hands. Their correspondence is lengthy, minute, and interminable; in spite of their concentration and look of reflection I could never bring myself to take them seriously, or feel that they were fully responsible for their thoughts and actsmachines only, wound up by school teaching, some going out of order and relapsing into savages and brutes.
  • 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:Round the railway station crowds the village of Chandernagore, the huts close together, with no land to spare, and at length we were in the city of houses, with broad terraces in front in a classic style, with colonnades and decorations in relief, and broad eaves overhanging for shade. And beautiful gardens, bougainvilleas, and almond trees, white-blossomed faintly touched with pink, hedge in streets with foreign-sounding names. The air was full of the fresh scent of water and greenery and of the blessed peace of silenceso rare in India.A little way off an old man was wrapping the naked body of a poor woman in a white cloth; then he fastened it to two poles to dip it in the river; finally, with the help of another Sudra, he laid the corpse on a meagre funeral pile, and went off to fetch some live charcoal from the sacred fire which the Brahmins perpetually keep alive on a stone terrace overlooking the Ganges. He carried the scrap of burning wood at the end of a bunch of reeds, and, praying aloud, walked five times round the pyre, which completely concealed the body. Then he gently waved the bunch of reeds, making them blaze up, and placed them beneath the wood, which slowly caught fire, sending up dense curling clouds of white vapour and slender tongues of flame, creeping along the damp logs that[Pg 167] seemed to go out again immediately. But suddenly the fire flared up to the top of the pile; the flesh hissed in the flame, and filled the air with a sickening smell.

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:"No."

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