TWO:I dont believe Ive introduced myself, the man began. Im Mr. Whiteside. Of course you wonder what I am here for.

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:In the swamp where the seaplane crashed! shouted Sandy, complimenting Dick with a sound smack on his back.
  • 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:Cope had landed his force at Dunbar on the very day that the prince entered Edinburgh. His disembarkation was not completed till the 18th. Lord Loudon had joined him at Inverness with two hundred men, and now he met the runaway dragoons, six hundred in number, so that his whole force amounted to two thousand two hundred mensome few hundreds less than the Highlanders. Sir John took the level road towards Edinburgh, marching out of Dunbar on the 19th of September. Next day Lord Loudon, who acted as adjutant-general, rode forward with a reconnoitring party, and soon came back at a smart trot to announce that the rebels were not approaching by the road and the open country to the west, but along the heights to the south. Sir John, therefore, altered his route, and pushed on to Prestonpans, where he formed his army in battle array. He placed his foot in the centre, with a regiment of dragoons and three pieces of artillery on each wing. His right was covered by Colonel Gardiner's park wall and the village of Preston; his left extended towards Seaton House, and in his rear lay the sea, with the villages of Prestonpans and Cockenzie. Between him and the Highlanders was a deep morass.How do they get these ice-cubes the same tint as the lemonade? Larry wondered, admiring the yellowish tone of the cubes, as he stirred the clinking mixture in his tall glass.

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

THREE:
  • 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:Just beforethe meeting here, sir!
