TWO:CHAPTER IV. WEAVING THE NET.On the next afternoon but one we heard that a great column of our soldiers was approaching on the nearest highway, bound up the railroad to Joe Johnston's army from the region about Port Hudson, and Charlotte instantly proposed that our ladies deal out food and drink from some shady spot on the roadside. It was one of those southern summer days when it verily seems hotter in the shade than in the sun--unless you are in the sun. The force was wholly artillery and infantry, the last Confederate infantry that region ever saw in column under arms; poor, limping, brown-faced, bloody-footed boys! their weapons were the only clean things, the only whole things, about them except their unbroken spirit; and when the very foremost command chanced to be one which the Harpers had seen in New Orleans the day it left there marching in faultless platoons and spotless equipments through the crowds that roared acclaim and farewell, our dear ladies, for one weak moment, wept.

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.

  • 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:CHAPTER XII.

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

THREE:Another ramble on shore the following morning, and they left the soil[Pg 311] of Japan for the deck of the steamer. At noon they were slowly moving down the bay; they passed the island of Pappenberg, and, as they did so, Frank read from a book he had picked up in the ship's cabin the following paragraph:No, he would not; only wagons went that way, to cross the creek by a small bridge. I could cut off nearly two miles by taking the bridle-path that turned sharply down into the thick woods of the creek-bottom about a quarter of a mile from the house and crossed the stream at a sandy ford. "Ride round," he said, "and I'll show you from the front of the house."
  • 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:Near the southern end of the bridge the boys observed something like a great sign-board with a railing around it, and a roof above to keep the rain from injuring the placards which were painted beneath. The latter were in Japanese, and, of course, neither Frank nor Fred could make out their meaning. So they asked the Doctor what the structure was for and why it was in such a conspicuous place.
