TWO:With tea a servant brought packets of betel in a chased gold box, with a lid imitating a lotus flower. Then, when everybody was served, he carefully replaced the precious object in an embroidered silk bag and disappeared.

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 110]Adinath, a Ja?n temple, is roofed with huge blocks of stone. The airy architecture is a medley of balconies, of pierced panels, of arcades in squares, in lozenges, in octagons; the two stories, one above the other, are on totally different plans, and along every wall, on every column and every balustrade runs a fatiguing superfluity of ornament, figures and arabesques repeated on the stone, of which not an inch is left plain.
  • 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:From Kusshalgar we were travelling in a tonga once more. The landscape was all of steep hills without vegetation; stretches of sand, hills of claylilac or rosy brick-earth scorched in the sun, green or brown earth where there had been recent landslips, baked by the summer heat to every shade of red. There was one hill higher than the rest, of a velvety rose-colour with very gentle undulations, and then a river-bed full of snowy-white sand, which was salt.Some prisoners were brought to the train; a single sepoy led them by a chain. Two carried enormous bales, and the third a heavy case. They packed themselves into a compartment that was almost full already, and one of a couple that were chained together by the wrists put the chain round his neck; then, when he had scraped acquaintance with the other travellers, he amused himself by tormenting the hawkers of drink and pastry, bargaining with them for a long time and buying nothing, quite delighted when he had put them in a rage with him.

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

THREE:In the island of Srirangam we visited a temple to Vishnu, enclosed within eight walls, of which the three first only contain any dwellings. A crowd of pilgrims swarmed about the steps, where everything was on sale: little gods in bronze, in painted marble, in clay, and in wood; paper for[Pg 111] writing prayers on; sacred books; red and white face-paints, such as the worshippers of Vishnu use to mark their foreheads with a V; little baskets to hold the colours, with three or four divisions, and a mirror at the bottom; coco-nuts containing kohl; stuffs of every dye; religious pictures, artless indeed, and painted with laborious dabs of the brush in the presence of the customer; chromo-lithographs from Europe, sickeningly insipid and mawkishly pretty.Birds, green, red, black, and gold-colour, fluttered gaily among the palms, the bamboos as tall as pine trees, the baobabs and mango trees; butterflies with rigid tails and large wings beating in uncertain flight, floated over the bright verdure flecked with sunshine. Round one pagoda, towering over a wretched village that lay huddled in the shade of its consecrated walls, a proud procession of stone bulls stood out against the sky, visible at a great distance in clear outline through the heated, quivering air.
  • 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:In the evening, lamps shining out through latticed windows lighted the faithful in their pious gymnastics. A moollah's chant in the distance rose high overhead, and very shrill, and in the darkness the stars shed pale light on the tombstones mirrored in the black water; a plaintive flute softly carried on the sound of the priests' prayers. Down the dark streets the folk, walking barefoot without a sound, and wrapped in white, looked like ghosts.
