TWO:DEHRA DOONOn the stone ceiling of almost every temple four large women's faces and certain crouching[Pg 75] gnomes appear in fresh red paint. In the very dim twilight that comes in through the narrow windows hung with blue gauze, the idols are visible behind lattices: white Buddhas blazing with sparkling gems that hang on their wrists and ankles, or form a perfect breastplate; and every one, without exception, has an enormous glittering imitation diamond in his forehead.

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:Many hapless creatures here suffer from elephantiasis, and even quite little children are to be seen with an ankle stiffened, or perhaps both the joints ossified; and the whole limb will by-and-by be swollen by the disease, a monstrous mass dreadfully heavy to drag about. Other forms of lupus affect the face, and almost always, amid a crowd watching[Pg 138] some amusing performance, a head suddenly appears of ivory whiteness, the skin clinging to the bone or disfigured by bleeding sores.And at this day the high road passes Secundra Bagh in ruins, and on the ground where Nana Sahib's soldiers fell, huge flowers are strewn of "flame of the forest" fading into hues of blood.
  • 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:More and yet more palaces; remains of marble porticoes and columns, walls covered with tiles glittering in the blazing sunshine like topaz and emerald; and over all the peace of dust and death, the only moving thing those vultures, in shades of dull grey almost indistinguishable from the colour of the stones.

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

THREE:There was a sort of murmur behind the door, like reciting a prayer, then louder tones, indeed a very loud shout, repeated three times by several voices at once; and then the one alone continued in a dull chant. The door was half opened and I was beckoned, but to enter alone.
  • 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:"Yes, I know. How much?"

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