TWO:"How much for this stuff?"

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:By three in the morning we had started on our way. At the very first streak of day, in front of us, on the road, was a snow-leopard, a graceful supple beast, with a sort of overcoat above its grey fur spotted with black, of very long, white hairs. It stood motionless, watching some prey, and it was not till we were close that it sprang from the road with two bounds, and then disappeared behind a rock with an elastic, indolent swing.
  • 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: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.Little beggar-girls with a depraved look, artful little hussies, pursued us coaxingly: "Give something, sahib, to pretty Cingalee girl, who wants to go over sea to where the gentlemens live."

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

THREE:The whole mausoleum, the terrace on which it stands, the four minarets as tall as light-towers, are all in dead white marble, the whiteness of milk and opal, glistening with nacreous tints in the brilliant sunshine under a sky pale with heat and dust.The Cingalese women, of languid gait, wear a long dark robe clinging about their legs and reaching to the ground. The poorer women have only a scanty saree to complete the costume; the more wealthy display stockings and boots; a white bodice cut low, with open sleeves and no basque leaves a roll of skin visible between the skirt and the bodice. The men wear a long loin-cloth of English trouser-stuff, a white jacket buttoned over the bare skin, and a twist of back hair like a woman's, in which they stick a celluloid comb, coronet-fashionsuch a comb as is used in Europe[Pg 125] to keep the hair back from a child's forehead. And all the race are too slender, too pliant, their eyes too long and slightly darkened with kohl; the boys especially have an unpleasant, ambiguous look.
  • 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.

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