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:"--With General Austin," I continued, "--and with Lieutenant Ferry?"
  • 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:"No, sir! I suppose it's true, but I never want to see her splendor shining through pock-marks." The reply won from him a gesture of approval, and this gave me a reckless tongue. "Why, if I were you, Lieutenant, she simply shouldn't go! Good Heaven! isn't she far enough away at the nearest? How can you tamely--no, I don't mean tamely, but--how can you endure to let this matter drift--how can you endure it?""I don't believe you! I don't believe you ever had cause for one!" She laid a hand again upon mine.

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

THREE:"I knew it! I knew it was her! Ah, you rogue, you know it was her!""In a little while after we went in, the performance began. A boy came into the ring from a room at one side of the tent, and he walked as if he were playing the king, or some other great personage. When he got to the middle of the ring, he opened a fan he carried in his right hand. He opened it with a quick jerk, as though he were going to shake it to pieces; and after he had opened it he announced the names of the wrestlers who were to come into the first act. If I hadn't been told what he was doing, I should have thought he was playing something from Shakspeare, he made such a fuss about it. Then he went out and the wrestlers came in, with a big fellow that Fred said must be the boss wrestler. He looked like an elephant, he was so big.
  • 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 stole through the cornfield safely; the frequent lightnings were still so well below the zenith as to hide me in a broad confusion of monstrous shadows. But when I came to cross the road no crouching or gliding would do. I must go erect and only at the speed of some ordinary official errand. So I did, at a point between two opposite fence-gaps, closely after an electric gleam, and I was rejoicing in the thick darkness that followed, when all at once the whole landscape shone like day and I stood in the middle of the road, in point-blank view of a small squad, a "visiting patrol". They were trotting toward me in the highway, hardly a hundred yards off. As the darkness came again and the thunder crashed like falling timbers, I started into the cotton-field at an easy double-quick. The hoofs of one horse quickened to a gallop. A strong wind swept over, big rain-drops tapped me on the shoulder and pattered on the cotton-plants, the sound of the horse's galloping ceased as he turned after me in the soft field, and presently came the quiet call "Halt, there, you on foot." I went faster. I knew by my pursuer's coming alone that he did not take me for a Confederate, and that the worst I should get, to begin with, would be the flat of his sabre. Shrewdly loading my tongue with that hard northern r which I hated more than all unrighteousness, I called back "Oh, I'm under orders! go halt some fool who's got time to halt!"
