TWO:492 The Russians did not attempt to march upon Berlin. About the middle of September General Soltikof gathered all his forces in hand, and commenced a march into Silesia to effect a junction with General Daun. Frederick followed, and, by a very rapid march, took possession of Sagan, on the Bober, where he was in direct communication with Henry. On the 24th of September the king wrote to his younger brother Ferdinand, in Berlin:

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:
  • 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 May the King of Poland returned the visit of Frederick William. He came with a numerous retinue and in great splendor. During the past year his unhappy wife had died; and he, then fifty-five years of age, was seeking to bargain for the hand of Wilhelmina, hoping, by an alliance with Prussia, to promote53 some of his political schemes. The wicked old Polish king was much broken by age and his terrible debaucheries. He had recently suffered the amputation of two toes from an ulcerated foot, which no medical skill could cure. He was brought into the palace at Berlin in a sedan, covered with red velvet embroidered with gold. Wilhelmina had no suspicion of the object of his visit, and was somewhat surprised by the intensity of his gaze and his glowing compliments. Diplomatic obstacles arose which silenced the question of the marriage before Wilhelmina knew that it had been contemplated.

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:I found him much grown; an air of health and gayety about him. He caressed me greatly. We went to dinner. He asked me to sit beside him. Among other things, he said that he liked the great world, and was charmed to observe the ridiculous, weak side of some people.It was but sixty miles from Prague to Tabor. The march of Fredericks division led through Kunraditz, across the Sazawa River, through Bistritz and Miltchin. It was not until the ninth332 day of their toilsome march that the steeples of Tabor were descried, in the distant horizon, on its high, scarped rock. Here both columns united. Half of the draught cattle had perished by the way, and half of the wagons had been abandoned.

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