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:[See larger version]It was not, however, till the 12th of August that they were ready with their batteries. The effect of the bombardment was almost instantaneous. Within six hours nearly all the enemy's guns were silenced, and the next day the Spaniards capitulated, agreeing to yield not only the place, and the vessels in the harbour, but the country for a hundred and eighty miles to the westward; in fact, all the best part of Cuba. The booty taken was valued at nearly three million pounds.
  • 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 Battle of Rosbach raised the fame of Frederick wonderfully all over Europe. He soon roused himself, however, for fresh efforts. Whilst he had been thus engaged on the Saale, the Austrians had again overrun Silesia, defeating the Prussians under the Duke of Bevern, storming the great fortress of Schweidnitz, and making themselves masters of Breslau, the capital. In spite of his reduced numbers and the advancing winter, Frederick immediately directed his march towards Silesia, gathering reinforcements as he went, so that by the 5th of December, just one month from the Battle of Rosbach, he came up with Prince Charles of Lorraine and Marshal Daun at Lissa, a small village near Breslau, and with forty thousand men encountered and defeated nearly seventy thousand Austrians, killing and wounding twenty-seven thousand of them, taking above fifty standards, one hundred cannon, four thousand waggons, and much other spoil. This battle at once freed Silesia from the Austrians, who trooped over the mountains in all haste, and left the victorious king to close this unexampled campaign.

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:France ceded Canada, Nova Scotia, and Cape Breton, stipulating for the free exercise of their religion by the inhabitants of Canada, and for their leaving the country if they preferred it, carrying away their effects, if done within eighteen months. Nova Scotia and Cape Breton were given up unconditionally. The boundaries of Louisiana were more clearly defined. The French retained the right to fish on part of the coast of Newfoundland and in the Gulf of St. Lawrence and to retain the two little islets of St. Pierre and Miquelon, as places of shelter for their fishermen, on condition that no batteries should be raised on them, nor more than fifty soldiers keep guard there. Their fishermen were not to approach within fifteen miles of Cape Breton.
