TWO:Outside, under a thatched screen, sits the punkah coolie, his legs crossed, the string in his hand; and as soon as everyone goes into the room he wakes up, rocks his body to and fro, his arm out in a fixed position, swaying all of a piece with a mechanical see-saw, utterly stupid. He will go to sleep lulled by his own rocking, and never wake unless the cord breaks, or somebody stops him.

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:
  • 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 went into the observatory, where the servants were sleeping in the open air on camp beds, lying across each other and blocking the entrance.[Pg 177] I went to gaze at the north star, looking very small, a tiny spangle of blue in the blue velvet sky, visible at the top of a crazy flight of steps that goes up to nowhere in the air from the topmost terrace.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.

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

THREE:And under an arcade priests were hanging the shrine with wreaths of pink and yellow flowers, in preparation for its nocturnal progress, while an old woman, all alone, was bathing in the tank, with much splashing and noise of waters.The forest round Kandy is glorious, an exuberance, a crush of trees growing as thick as they can stand, the dense tangle of boughs and leaves outgrown by some enormous ficus, or tall terminalia, whose sharp, angular roots have pushed through the soil while its trunk, twisting in a spiral, has made its way to a prodigious height, ending a thick dome of foliage. This, again, is overgrown by delicate creepers decking the green mass with their flowers. Spreading banyans, with a hundred stems thrown out like branches and ending in roots, form colonnades of a rosy grey hue like granite, and might seem to be the vestiges of some colossal church with a dark vault above, scarcely pierced here and there by a gleam of blue light from the sky beyond. Among these giants of the forest dwells a[Pg 131] whole nation of bending ferns as pliant as feathers, of clinging plants hanging in dainty curtains of flowers from tree to tree. Sometimes between the screen of flowers a bit of road comes into view, deep in impalpable brick-red dust, of the same tint as the fruits that hang in branches from the trees.
  • 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:After him came another little Hindoo, dragging a mongoose, very like a large weasel with a fox's tail. He took a snake out of a bag, and a battle began between the two brutes, each biting with all its might; the sharp teeth of the mongoose tried to seize the snake's head, and the reptile curled round the mongoose's body to bite under the fur. At last the mongoose crushed the serpent's head with a fierce nip, and instantly a hawk flew down from a tree and snatched away the victim.A poor sick ape, beaten by all the others, sat crying with hunger at the top of a parapet. I called her for a long time, showing her some maize on a tray. At last she made up her mind to come down. With the utmost caution she reached me, and then, after two or three feints, she struck the platter with her closed fist, sending all the grain flying. Utterly scared, she fled, followed to her perch by a whole party of miscreants roused by the gong-like blow on the tray. Others stole into the temple to snatch the flowers while the attendant priest had his back turned; and when I left they were all busily engaged in rolling an earthenware bowl about, ending its career in a smash. In front of the temple the crimson dust round a stake shows the spot where every day the blood is shed of a goat sacrificed to the Divinity.
