TWO:Halting at noon at Kohala, we found a barber in the open street shaving and snipping his customers. In a cage hanging to the bough of a tree above his head a partridge was hopping aboutblack speckled with white, and gold-coloured wings. It had a strident cry like the setting of a saw.

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:[Pg 40]The air is heavy with indefinable perfume. We are already coasting the Indian shore, but it remains invisible, and gives no sign but by these gusts of warmer air laden with that inscrutable aroma of musk and pepper. A lighthouse to port, which we have for some time taken for a star, vanishes in the light mist that hangs over the coast, and then again there is nothing but the immensity of waters under the clear night, blue with moonlight.
  • 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 children of the bazaar watched them pass, holding out in their fingers scraps of foodthe remains of cakes, green fruit, or handfuls of rice, and the famishing creatures quarrelled for the morsels, frightening the little ones, who fled. Then they disappeared silently under the awnings, filling the air with a smell of dust and pepper, scaring the pigeons away from the pool for ablutions, and the birds fluttered up in dismay in the rosy sunset glow, seeking some other refuge for the night.Then, in a blaze of coloured fire, a fortissimo of music, and a whirlwind of drapery, they stopped exhausted in front of the idol. The lights were put out, the tom-toms were the only sound, and the procession moved on, escorting the shrine which glittered for some time yet, till it disappeared at an angle, leaving the temple in darkness just tinted blue by the moon.

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

THREE:Everything seems fused in a haze under the sun, as it grows hotter and hotter, and in that quivering atmosphere looks like a mass in which red and white predominate, with the persistent harmony of motion of the swaying, barefooted crowd.
  • 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.
