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.

It is often considered the most furious battle which was ever fought. While Frederick was engaged in this arduous campaign in the extreme north, driving the Russians from the Prussian territory, an Austrian army, ninety thousand strong, under General Daun, was endeavoring to reconquer Saxony. The Prussian king had left his brother Henry in defense of the province, with a small force garrisoned in the city of Dresden.
  • 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:In a pet Frederick left the room. The heroic general, who had flatly refused to obey a positive command, found it necessary to resign his commission. The next day another officer plundered the castle. Seventy-five thousand dollars of the proceeds of the sale were appropriated to the field hospitals. The remainder, which proved to be a large sum, was the reward of the plundering general.But the ever-vigilant Frederick had smuggled a false sister into the society of the Catholic ladies, who kept him informed of every measure that was proposed. At the very hour when Frederick was dining with the two English ministers, and making282 himself so merry with jests and banter, he was aware that General Neipperg, with the whole Austrian army, was crossing the River Neisse, on the march, by a route thirty miles west of his encampment, to take Breslau by surprise. But he had already adopted effectual measures to thwart their plans.

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

THREE:The region thus annexed to Prussia was in a deplorable state of destitution and wretchedness. Most of the towns were in ruins. War had so desolated the land that thousands of the people were living in the cellars of their demolished houses.
  • 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:Be firm, my child. Trust in my management. Only swear to me, on your eternal salvation, that never, on any compulsion, will you marry another than the Prince of Wales. Give me that oath.

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
