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:KOHAT"The mother of Christ."
  • 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:These gentlemen of the Civil Service would put in an appearance "now and then"the eternal "now and then" that answers every question in India. They stepped out of a buggy, walked quickly round, had seen, and were gone again in a great hurry to finish some important work for the next European mail.

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

THREE:Servants carrying large trays offer the company certain strange little green parcels: a betel-leaf screwed into a cone and fastened with a clove, containing a mixture of spices and lime, to be chewed after dinner to digest the mass of food you may see spread out in the tables in the dining-room.AMRITSUR
  • 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:Figures draped in pale muslins brushed past us, hastening to the door. Flower-sellers, in one of the arcades, were hurrying to finish their garlands; and suddenly, close before usa mass that looked as if it were part of the temple itselfan enormous elephant started into sight, passed on and vanished in the darkness.

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