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:[Pg 197]There was no time for speech. The shot was not a signal, yet on the instant and in our very teeth, on our right and our left, the cross-fire of the hidden and waiting foe flashed and pealed, and left and right, a life for a life, our carbines answered from the saddle. For a moment the odds against us were awful. In an instant the road was so full of fallen horses and dismounted men that the jaded column faltered in confusion. Our cunning enemy, seeing us charge in column, had swung the two extremes of their line forward and inward. So, crouching and firing upon us mounted, each half could fire toward the other with impunity, and what bullets missed their mark buzzed and whined about our ears and pecked the top rails of either fence like hail on a window. A wounded horse drove mine back upon his haunches and caused him to plant a hoof full on the breast of one of our Louisianians stretched dead on his back as though he had lain there for an hour. Another man, pale, dazed, unhurt, stood on the ground, unaware that he was under point-blank fire, holding by the bits his beautiful horse, that pawed the earth majestically and at every second or third breath blew from his flapping nostrils a cloud of scarlet spray. They blocked up half the road. As we swerved round them the horse of the company's first lieutenant slid forward and downward with knees and nose in the dust, hurling his rider into a lock of the fence, and the rider rose and rushed to the road again barely in time to catch a glittering form that dropped rein and sword and reeled backward from the saddle. It was his captain, shot through the breast. An instant later our tangled column parted to right and left, dashed into the locks of the two fences, sprang to the ground, and began to repay the enemy in the coin of their own issue. Only a dozen or so did otherwise, and it was my luck to be one of these. Espying Ned Ferry at the very front, in the road, standing in his stirrups and shouting back for followers to carry the charge on through, we spurred toward him and he turned and led. Then what was my next fortune but to see, astride of my stolen horse, the towering leader of the foe, Captain Jewett.
  • 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:"Never! About herself? no, sir!" He bent and whispered: "She despises him; she keeps in with him, but it's to get the news, that's all; that's positively all." On our way to the stable to saddle up--for we were all going to church--he told me what he knew of her story. I had heard it all and more, but I listened with unfeigned interest, for he recited it with flashes of heat and rancor that betrayed a cruel infatuation eating into his very bone and brain, the guilt of which was only intensified by the sour legality of his moral sense.His gaze was grateful. She spoke again: "I suppose I oughtn't to mind it."

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

THREE:The steamer descended the Woosung River to its intersection with the Yang-tse-kiang, and then began the ascent of the latter. The great stream was so broad that it seemed more like a bay than a river. This condition continued for a hundred and fifty miles, when the bay narrowed to a river, and the far-famed Silver Island came in sight. It stands in mid-stream, a steep hill of rock, about three hundred feet high, crowned with a pagoda, and covered from base to summit with trees and bushes and rich grass. At first it might be taken for an uninhabited spot, but as the boat approaches you can see that there are numerous summer-houses and other habitations peeping out from the verdure. A little beyond the island there is a city which straggles over the hills, and is backed by a range of mountains that make a sharp outline against the sky. This is Chin-kiang, the first stopping-place of the steamer as she proceeds from Shanghai to Han-kow. She was to remain several hours, and our friends embraced the opportunity to take a stroll on shore. Here is Frank's account of the expedition:
  • 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.

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