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:"Ah, but we move south at day-light; the prisoners and wounded we send east, to Hazlehurst," said our leader, with a restraining hand on Quinn's knee. The other lieutenant made some inquiry of him, and the doctor was ignored, but stayed on, and as I stood waiting to be noticed I gathered a number of facts. The lightly injured would go in a plantation wagon; for the few gravely hurt there was the Harpers' ambulance, which had just arrived to take the ladies back to Squire Wall's, near Brookhaven, alas! instead of to Louisiana. For the ladies Charlotte's spring-wagon was to be appropriated, one of them riding beside it on horseback, and there was to be sent with them, besides Charlotte's old black driver, "a reliable man well mounted." Whoever that was to be it was not Harry, for he was to go south with a small guard, bearing the body of the Louisiana captain to his home between the hostile lines behind Port Hudson."My dear madam, you don't realize ours. We don't want to imprison women."
  • 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:I saw Mrs Fyson this afternoon, she said, beginning gently.
  • 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:"The ship had taken its cargo at Macao, and we went out to sea with a fine breeze. We had over a thousand 'passengers' in the hold, and only a small number were to be allowed on deck at one time, as several ships had been captured by the coolies, and we did not intend to be taken if we could help it. Two days after we started there was trouble among the coolies, and several of them ran about the space below-deck and threatened to set the ship on fire. They did build a fire of some of the dry boards used for making their sleeping-berths; but we covered the hatches with tarpaulins, and held the smoke down there, so that the coolies were nearly smothered and compelled to put the fire out themselves.OVERLAND TO CALIFORNIA.
