TWO:THE ASCENT OF FUSIYAMA.

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:"The Nan-kow Pass is about thirteen miles long, and the road through it is very rough. The mountains are steep, and we saw here and there ruins of forts that were built long ago to keep out the Tartar invaders of China. Our animals had several falls, but they got through without accident, and, what was more, they brought us to a village where there was an inn with something good to eat."Ah, now he is discovered, surely not. I think he will turn back at Wiggins."
  • 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:I remember you told me once he was a cad. I shall go to bed, I think.George greeted the travellers with all the dignity of an emperor saluting an embassy from a brother emperor, and wished them welcome to his roof and all beneath it. Then he straightened up to the very highest line of erectness, and rested his gaze upon Doctor Bronson.

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

THREE:But the class to which the Paynes belonged were not really humble. They were urban in origin, and the semi-aristocratic tradition of Great Wymering was opposed to them. They had come down from the London suburbs in response to advertisements of factory sites, and their enterprise had been amazing. Within a few years Great Wymering had ceased to be a pleasing country town, with historic associations dating back to the first Roman occupation; it was merely known to travellers on the South-Eastern and Chatham railway as the place where Payne's Dog Biscuits were manufactured.In front of a house by the roadside some coopers were hooping a vat, and Frank instantly recognized the fidelity of a picture he had seen by a native artist showing how the Japanese coopers performed their work. They make excellent articles in their line, and sell them for an astonishingly low price, when we compare them with similar things from an American maker. The fidelity of the work is to be commended, and the pails and tubs from their hands will last a long time without the least necessity of repairs.
  • 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:"We had a long search among the porcelain shops for some blue china plates of what is called 'the willow pattern.' We must have gone into twenty shops at least before we found them; and, finally, when we did get them, the dealer was as anxious to sell as we were to buy. He said he had had those plates on hand a very long time, and nobody wanted them. We did not tell him how rare they are at home, and how anxious people are to get hold of them.
