TWO:Between the houses tiny garden-plots full of flowers surround gravestones, on which fresh roses are constantly laid.

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:Pilgrims crowd the courts and the temples. All, when they speak, hold a hand or a corner of their[Pg 76] robe before their lips to avoid swallowing the tiniest insect, which would avert the favour of the gods. They bring offerings of rice or gram in little bags of faded silk, pale pink, or green, and gold thread; the poorest have bags of red and white beads.After dinner, with the dessert, the head orderly of the mess marched in with the decanters. He set them on the table, and then stood immovable at his post behind the colonel's chair, shouldering his gun till everybody had done, when he carried off the bottles with the same air of being on parade.
  • 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:

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

THREE:The colouring in all these rock-temples is a softened harmony of yellow stone, hardly darkened in some places, forming a setting for the gaudier tones of the idols, all sparkling with gold and showy frippery.After inspecting my little permit to visit the Khyber, the officials at the fort had placed in my carriage a soldier of the native Khyber rifle-corps, six feet six in height, placid and gentle. When I got out of the carriage to walk up a hill he would follow a yard or so behind, and watching all my movements, looked rather as if he were taking me to prison than like an escort to protect me.
  • 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:Inside the temple was the fragrance of fresh flowers, brought as offerings, with grains of rice threaded like semi-transparent beads on the flexible pale green stem. A huge Buddha here, of many-coloured stones bedizened with gold, gleams in the[Pg 128] shade of the altar, and two bonzes in front of the idol were quarrelling at great length, with screams like angry cats and vehement gesticulations, for the possession of some small object which constantly passed from one to the other.
