TWO:Trees shut in the flat, interminable road, and it was midnight before we reached Srinagar, where I found, as a surprise, a comfortable house-boat with inlaid panels, and a fragrant fire of mango-wood smelling of orris-root.

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 front of a statue of Kali with a hundred arms, surrounded by rough votive offerings carved in wood, most of them representing legs, a man was pouring out rice, and a whole flight of grey leilasbirds like magpiesalmost settled on his hands: birds of the temple, so familiar that one even allowed me to catch it, and did not fly away at once when I set it at liberty. There are rows of black Buddhas, white Buddhas, Sivas painted redterriblestraddling in fighting attitudes; pilgrims without end bow and pray in front of each idol.
  • 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:

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

THREE:After passing the temples and tombs that surround the Khoutab, the town of ruins lies scattered over the plain of pale sand and withered herbage.
  • 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:The cathedral, embowered in shrubs and tall banyans, stands on a square, where a pedestal awaits the bust of Dupleix.
