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 tea plantationa garden of large shrubs pruned[Pg 293] in such a way as to secure the greatest possible growth of young shoots, and above the delicate tea plants a shady hedge of fan palms and taller trees. The leaves are gathered by day, spread in the evening on hurdles and left for the night in open sheds. On the morrow they are first thrown into a sort of bottomless square funnel which revolves on a board; rolled and broken in this machine they are ready for drying. The tea passes through twenty grades of increasing temperature, and in drying it gives out the most delightful aromaa mixture of sweetbriar, seaweed, and violets, with a scent of tea too. The leaves are finally sifted, which sorts them in four sizes into boxes containing the different qualities.
  • 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:[Pg 19]Here in southern India the women wear hardly any trinkets, and their garb consists of sarongs and sarees, so thin that their shape is visible through the light stuff. In their hair, which is knotted low on the neck, they stick flowers, and occasionally light trailing sprays fall down on the throat. They all have gold studs screwed into the two upper front teeth; hideous are these two red-gold teeth among the others, sound and white under young lips!

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

THREE:At the door of the house the sick man's wife was washing a white robe, in which he would be dressed for the grave on the morrow. The nearest relation of the dying must always wash his garment, and the woman, knowing that her husband had the plague and was doomed, as she was required by ritual to prepare for the burial while her husband was yet living, wore a look of mute and tearless resignation that terrified me.
  • 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:Near the statues, which are placed in a row close to the wall, other statues, finer, slenderer, and more graceful, stood before the pedestals, anointing the stone with some oil which in time soaks in and blackens it, or else hanging lanterns up over the divinities. These were the temple servants, wearing nothing but the langouti tied round their loins; they either shuffle about barefoot, or remain motionless in rapt ecstasy before the little niches where the idols grin or scowl among branches of roses and amaryllis.Between the large parasols are thousands of little pagodas, formed of four columns and a roof, and sheltering idols wreathed with flowers, to whom the faithful pray and bring offerings. Garlands are for ever floating down-stream, jasmine and Indian pinks, and patches of scattered rose petals; and on the banks of the river, where the sand forms little bays, flowers lie in a hem of delicate colours.

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