TWO:About Lahore, all among the ruined temples, the crumbling heaps of light red bricks sparkling with mica, there were fields of roses in blossom and of ripe corn. Naked coolies were labouring in the fields, gathering the ears one by one into quite small bunches; they looked like children playing at harvesting.

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:After the giant a whole chain of lavender and rose-coloured peaks turning to blue came into sight in the marvellously clear atmosphere; then the sun rose below us, in the throbbing tide of heat the mountains seemed to come closer to us, but immediately the mist gathered about Gaurisankar. "The Apsaras wearing impenetrable veils, that mortals may not gaze too long on the throne of the gods,"[Pg 152] said my sa?s, who had fallen on his face since the first appearance of the snow-crowned colossus, with hands upraised towards the paradise of Indra.As we approached the Afghan frontier, camp followed camp, clustering round the railway stations that lie closer together on the line. In the morning and towards evening there was a constant hum round the train, of bagpipes, bugles, and drums, and the red or grey ranks were to be seen of soldiers at drill.

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

THREE:A portico, supporting two stories of an unfinished building, forms the principal entrance; the pilasters are crowned with massive capitals scarcely rough-hewn in the stone. This porch alone gives an impression of repose, from its simplicity of line amid the medley of statues and incongruous ornaments loaded with strong colours, which, diminishing by degrees, are piled up to form each temple, ending almost in a spire against the sky. Vishnu, reclining on the undulating rings[Pg 112] of Ananta Sesha the god of serpents, whose name is the Infinite; idols with human faces riding on bulls, and elephants, and prancing horses; terrible Kalis with two fists rammed into their mouth, and six other arms spread like open wings; Ganesa, the elephant-headed god, ponderously squatting, his hands folded over his stomach; Garudha, the bird-headed god, ridden by Vishnu when he wanders through space; Hanuman, the monkey god, perched on a pedestal in an acrobatic attitude, the face painted bright green; gods of every size and every colour mixed up in a giddy whirl, round and round to the very summit of the structure.
  • 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 soon as we returned to Palitana the Rajah sent to inquire after me, and to present me with round boxes of fruit preserved in Cashmere, oval green grapes, each wrapped separately in cotton and smelling of honey.On quitting Hyderabad, to the right and left of the iron road, the landscape was for a long way the same; rocks, that looked as if they had been piled up and then rolled over, lay in russet heaps among peaceful little blue lakes without number, breaking the monotony of the wide, scorched fields, a sheet of pure gold. At one of the stations a beggar was rattling his castanets furiously, and singing something very lively and joyous. At the end of each verse he shouted an unexpected "Oh!" just like the cry of a Paris ragamuffin.
