TWO:There was not a sound, not a bird, excepting on the fringe of the forest. As we penetrated further there soon was no undergrowth even on the dry soil, between the ever closer array of trees; the creepers hung very low, tangled with clinging parasites; and between the stilt-like and twining roots and the drooping boughs, the path, now impracticable, suddenly ended in face of the total silence and black shade that exhaled a strong smell of pepper, while not a leaf stirred.

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:"Yes, I know. How much?"
  • 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:We saw the Jasmine tower from a corner of the garden in the glow of sunset. With its gilt cupola blazing in the low beams, its amber-hued walls as transparent as melting wax, and its pierced screen-work, it looked so diaphanous, so fragile, that it might be carried away by the evening breeze. And beyond the pavilion, above the ramparts carved with huge elephants, lies the old Hindoo palace, deserted by Jehangir for his house of pale marblesan endless palace, a labyrinth of red buildings loaded to the top with an agglomeration of ornament supporting flat roofs. And pagodas that have lost their doors, a work of destruction begun by Aurungzeeb. One court is still intact, overhung by seventy-two balconies, where the zenana could look on at the dancing of bayadres. Perfect, too, is the queen's private apartment, with two walls between which an army kept guard by day and by night.Close to a field that had just been reaped four oxen yoked abreast were threshing out the grain, tramping round and round on a large sheet spread on the ground. The driver chanted a shrill, slow tune; further away women in red were gleaning, and a patriarch contemplated his estate, enthroned on a cart in a halo of sunset gold.

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

THREE:In front of these stolid-looking sepoys, their black heads and hands conspicuous in their yellow uniforms, are drilled to beat of drum, marking every step and movement.
  • 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 train to Delhi the windows were screened with cuscus mats constantly sprinkled with water, and so long as the train was in motion the air came in cool, fragrant, and breathable. But whenever we stopped in the desert which this country becomes just before the monsoon, melted lead seemed to scorch up the atmosphere and shut the train in between walls of fire.We drove across a succession of parks to visit[Pg 175] Sumer Mundir, a too elaborately carved temple, the panels representing scenes from the Ramayana set in ornamental borders. On the roof, which bristled with sculptured stone, thousands of blue pigeons were perched asleep, their iridescent plumage scarcely stirring in the sunshine. Beyond a tank at the end of the park was a palace in the Arab style with incredibly delicate ornaments of wrought marble, open halls painted in subdued colouring, and lighted by the golden reflections from the water. The pool had steps all round it, in which crowds seat themselves on the occasions of pilgrimage, and far away the enchanting vision of Benares, the holy city, in every shade of amber and honey.
