TWO:Whenever our green driver meets another ekka-driver they both get off their perch and take a few puffs at the hookah that hangs in a bag at the back of the vehicle.

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:A very solid structure, with walls like a fortress, contains the treasury of the sacred mount. Five guards in turn came to open as many padlocks, and at last the ponderous door turned slowly on its hinges. A car, an elephant, and a vehicle to which are harnessed two prancing horses, are all brought out to convey the idols when they go forth in a[Pg 81] procession. The animals are chased with almost artistic skill. The harness, starry with precious stones, all takes to pieces.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.
  • 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 drill sergeant shouts the word of command in wonderful Englishlept, meaning left.

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:He appeared without a sound, visible only as a white figure, his brown face lost, effaced in the gloom of the dimly-lighted room. For a moment I had a really uncanny sensation at this headless apparition, but in an instant there was the gleam of a row of brilliant teeth, the light in the eyes, and the eternally smiling face of the household coolie.

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