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:And of all the victims of the disaster those I had just seen were not the most to be pitied. It was on families of high caste, men who might not work and whose wives must be kept in seclusion, that the famine weighed most cruelly. At first they borrowed money (and the rate of interest recognized and tolerated here is seventy-five per cent.), then they sold all they could sell. Bereft of every resource, unable to earn anything in any way, regarding the famine as an inevitable infliction by the incensed gods, they let themselves starve to death in sullen pride, shut up in their houses with their womankind. Thus they were the most difficult to rescue. Their unassailable dignity made them refuse what they would have regarded as charity, even to save the life of those dearest to them, and it needed the angelic craft of the women of the Zenana Mission to induce the kshatriyas to accept the smallest sum to keep themselves alive.
  • 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:We were off by break of day. Among hanging creepers, shrubs, and trees, temples, gilded by the rising sun, gleamed dimly through the rosy mist, and faded gradually behind a veil of white dust raised by the flocks coming down from Roza, or melted into the dazzling blaze of light over the distance.

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:All along the narrow streets, paved with broad flagstones up and down in low irregular steps, stand the five hundred temples of Benares, and between them houses with carved stone porticoes. The ochre-coloured stone, of which they all are built, is toned in places by a coating of reddish purple, faded by the rain and sun to pale flesh-colour, with an undertone of the yellow wall; and this takes on a glow as of ruby and sunset fires in the watery ripple reflected from the rivera mingling of every hue of intense sunshine, filtering through the awnings spread over the balconiesa glory of repose, tender and clear, which seems to emanate from the objects themselves, and to envelop them in a fine powder of light.Then the procession, with music, makes its way back to the bridegroom's house. On the threshold the priest says one more short prayer over the bowed heads of the newly-married couple, and at last the whole party go into the room, where the guests take their places at the long tables.

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