TWO:Over the rice-fields, in the darkness, danced a maze of fire-flies, quite tiny, but extraordinarily bright; they whirled in endless streaks of flame, intangible, so fine that they seemed part of the air itself, crossing in a ceaseless tangle, faster and faster, and then dying out in diamond sparks, very softly twinkling little stars turning to silver in the moonlight.

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:Another sanctuary holds an idol made of seven metals mingled to a pale golden hue. The statue is loaded with jewellery of silver and precious stones. On its head is a fan-shaped diadem starred with rubies. The walls and columns, of a dull purple, are decorated with gaudy mosaic of scraps of looking-glass set in brass along the lines of the mouldings.
  • 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 different scene indeed next day, with none of the magnificence of yesterday, was the temple of magical lights. There was a dense crowd of shouting and begging pilgrims. Along the pyramidal roofs, as at Srirangam, there were rows of painted gods, but in softer and more harmonious hues. Over the tank for ablutions was a balcony decorated in fresco, representing in very artless imagery the marriage of Siva and Parvati. The couple are seen holding hands under a tree; he a martial figure, very upright, she looking silly, her lips pursed, an ingnue. In another place Siva sits with his[Pg 120] wife on his knees, she has still the same school-girl expression. Finally, on the ceiling, is their apotheosis: they are enthroned with all the gods of Ramayana around them, and she looks just the same. The red and green, subdued by the reflected light from the water, were almost endurable.

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

THREE:The fort of Allahabad, the fort of the mutiny of 1857, is a complete citadel where, in the thickness of the walls, behind screens of acacia trees, lurk doors into palaces. Among the gardens there are clearings full of guns and ambulance waggons, and enormous barracks and huts for native soldiers. Then on the ponderous stonework of the ramparts rise little kiosks in the light Hindoo-Mussulman style, elaborate and slender, built by Akbar the [Pg 183]conqueror, who took Prayag and razed it, to build on the site a city dedicated to Allah. And now modern architecture is slowly invading it, adding to the flat walls which hide under their monotony the gems of stonework with their elegant decoration.
  • 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:Round the railway station crowds the village of Chandernagore, the huts close together, with no land to spare, and at length we were in the city of houses, with broad terraces in front in a classic style, with colonnades and decorations in relief, and broad eaves overhanging for shade. And beautiful gardens, bougainvilleas, and almond trees, white-blossomed faintly touched with pink, hedge in streets with foreign-sounding names. The air was full of the fresh scent of water and greenery and of the blessed peace of silenceso rare in India.
