TWO:In the middle of a garden, full of clumps of flowering shrubs standing on green lawns, is the Nadjiff Ackraff, a vast rotunda crowned with gilt[Pg 188] cupolas and spires, and all round the building is an arcade built in a square and studded with iron pins on which thousands of wax lights are stuck on the evenings of high festivals.

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 once more in a barge on the Ganges. The atmosphere seemed faintly iridescent, like mother-of-pearl, the silence serenely lulled by the distant sound of a flute. The palaces and temples, reflected in the still water, looked in the distance like forts crowned with turrets of gold, and their little windows like loopholes. The broad stairs of the quays, where the priests' umbrellas glitter, assumed a spacious, unfamiliar dignity, the red colour shading paler towards the bottom, where it was washed off by the lapping Ganges, looking as though a fairy hanging of gauze were spread under the wavelets in honour of the Apsaras and the divinities of the river.Towards noon the mass of Kinchinjunga again lifted its head above the clouds, now white with a dust of rosy gold or violet on the snow in the shadows; and again, as the clouds swept across, of every changing tint of steel and copper, pearl and sunshine, till, following on the ardent glory of sunset, a purple and living fire, like a flame within the very substance of the ice-fields, all died into[Pg 153] mysterious blueness under the broad pure light of the moon.
  • 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:A poor old fellow, behind a grating that shut him into a kind of hovel, called out to us, first beseeching and then threatening, rushing frantically to the back of his hut and at once coming forward again with fresh abuse. He was a dangerous madman, placed there to keep him out of mischief and to be cured by the Divinity.

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

THREE:The orchestra, consisting of a harmonium, a violin, and a darboukha, played a languishing, drawling air to a halting rhythm, while the chorus, standing in a line on the stage, sang the introductory verses.When a native comes to ask a favour he brings a few rupees in his hand, and the patron must take them and hold them a few minutes. A retired Sikh trooper had come to see his son, now a soldier in the regiment, and met the colonel, who asked him whether he could do anything for him, to which the other replied:
  • 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:Then the sunset, in the furnace of heavy purple and red, reflected in the water in fiery copper-colour streaked with violet, till soon it all faded together, to gold, to lemon-colour; the mist rising from the river spread over all the country, and everything looked the same in the cloudless gloom. One quarter of the sky glowed faintly, through the haze a crimson globe rose into view, the moon appeared, and soon lighted up all the sky with a soft greenish glow, pallid but deep, lying on the tranquil Ganges in broad rippling sheets of gold and green, spangled with light where a fish leaped, or a white bird dipped its wing as it skimmed swiftly across without a sound. The gold grew cold and dead, the moon turned to steel against the intensely blue sky, to cold blue steel on the lustrous face of the waters.At the very top of the incline, the enclosing wall, black with age but bright with yellow velvet moss, rises precipitously above the plain, and three light balconies, with columns as slight as flower-stems,[Pg 77] crowned with pointed roofs recurved at the angles, overhang the abyss.

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