TWO:In front of a Buddhist temple were some tanks in which enormous tortoises were swimming. On the building, above carvings of elephants in relief on the stone, were a number of mural paintings, artless and terrible scenes set forth with the utmost scorn of perspective and chiaroscuro: a place of torment where green monsters thrust the damned against trees of which the trunks are saws, and enormous red and yellow birds devour living victims.

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.

  • 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:In the heart of an extensive park, where wide lawns are planted with gigantic baobabs and clumps of bamboo and tamarind, stands an important-looking building, hideously modern in a mixture of heterogeneous styles and materials, of a crude yellow colour, and much too new. There is no attempt at unity of effect. A central dome crowns the edifice and a square tower rises by the side of it. Some portions, like pavilions, low and small, carry ornaments disproportioned to their size; while others, containing vast halls, have minute windows pierced[Pg 52] in their walls, hardly larger than loopholes, but framed in elaborate sculpture and lost in the great mass of stone. Arcades of light and slender columns, connected by lace-like pierced work of alarming fragility, enclose little courts full of tree-ferns and waving palms spreading over large pools of water. The walls are covered with niches, balconies, pilasters, and balustrades carved in the Indian style, the same subjects constantly repeated.Among the officers was a young lady on horseback, her black habit covered with dust. Instead of the pith helmet that the English ladies disfigure themselves by wearing, she had a straw hat with a long cambric scarf as a pugaree. She was pretty and sat well, and at the last turning she pulled up and watched the men, the ammunition and the baggage all march past, saluted them with her switch, and cantered off to the town of "cottages." I saw her again in the afternoon, taking tea in her garden as she sat on a packing-case among eviscerated bales, and giving orders to a mob of slow, clumsy coolies, who were arranging the house.

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

THREE:Every house in the town was shuttered, not a soul was to be seen in the baked streets; only here and there in a shady corner a beggar might be seen asleep. A chigram only was slowly moving along at the slow pace of two draught oxen, carrying the women of a zenana, and their constant chatter[Pg 300] within the curtains of the clumsy vehicle sounded formidably loud and discordant in the silence, the death-like exhaustion of noon. A foxy smell came up from everything that the sun was baking, and towards the end of the day it had become intolerable, corpse-like. It died away, however, after sunset.In the ward we had just passed through there were none but convalescents or favourable cases. At the further end of the room a boy, fearfully emaciated, so thin that his body, lying in the hollow of the mattress, was hardly visible under the covering, was asleep as we approached. He had come from one of the famine districts, and in escaping from one scourge had come to where the other had clutched him. The doctor touched him on the[Pg 34] shoulder, and he opened his great splendid eyes. The awakening brought him gladness, or perhaps it was the end of his dream, for he had the happy look of a contented child, shook his shaven head waggishly, and the single corkscrew lock at the top, and was asleep again instantly.
  • 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:As we went down to the shore a whole swarm of little dark boys wanted to sell scarabs, rattans, birds' nests shaped like pockets, and dream-flowers, gathered from the creepers on the temples; large almond-scented lilies, and hanging bunches of the ebony-tree flowers, so fragile in texture and already faded in the sun, but exhaling till evening a faint perfume of verbena and lemon.
