TWO:Very gradually the measure quickened, the pitch grew shriller, and with faster and freer movements the bayadres were almost leaping in a sort of delirium produced by the increasing noise, and the constantly growing number of lights.

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:In the atmosphere floated a pale blue smoke, rising from a heap of weeds that some children were burning, a weird sort of incense, acrid and aromatic, fading against the too-blue sky.
  • 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:And then seeing that I did not go, that on wakening again from his dream I was still there, he fixed his eyes on me and caught sight of a medal that I wear.

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:Through the half-open doors in the courtyards bones were bleaching, almost buried under the fine powder that lies on everything. And from this dust, as we trod it, rose a sharp smell of pepper and smoke. Twisted branches drooped forlorn from the skeletons of a few trees that were left standing. Parasitic creepers had woven a flowing robe of tangle over a statue of Kali, left unbroken in front of a small temple in ruins; and all over the withered[Pg 198] and faded growth the fine white dust had settled in irregular patterns, a graceful embroidery rather thicker in the folds.ELLORA
