TWO:They were off at an early hour, and, as before, their route was along the Tokaido. The provisions and other things had been sent on ahead during the night, and they did not see them until they came to the place where they were to sleep. They took a light meal before starting from Yokohama, and found a substantial breakfast waiting for them at Totsooka. Their host was a famous character in the Eastan English actor who had drifted through China and Japan, and finally settled down here as a hotel-keeper.

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:"By all means," replied the Doctor, with a smile; "it is time to begin at once. You are in a foreign country and there are plenty of things to write about. Your information will be to a great extent new and interesting to your friends, and the reasons that I gave you for not writing a long letter from Niagara do not exist here."
  • 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:Early on the second morning after their arrival, they started for the final effort. They rode their horses as far as the way was practicable, and then proceeded on foot. Their baggage was mostly left in charge of the grooms to await their return, and such provisions and articles as they needed were carried by "yamabooshees," or "men of the mountain," whose special business it is to accompany travellers to the summit, and to aid them where the way is bad, or in case they become weary. If a person chooses, he may be carried all the way to the top of the mountain and back again; but such an arrangement was not to the taste of our robust adventurers. They were determined to walk, and walk they did, in spite of the entreaties of the coolies who wanted to earn something by transporting them. In addition to the yamabooshees, they had an escort of two "yoboos," or priests, from one of the temples. These men were not expected to carry burdens, but simply to serve as guides, as they were thoroughly familiar with the road and knew all its peculiarities.Instantly he saw his mistake. He had had the opportunity to treat the subject in the same playful spirit. But he had been unable to: it was all too serious to him. The grim Puritan streak in him, which had not prevented his falling in love with Norah, made it impossible for him to jest or suffer a jest about it. He was not a flirt, and did not care to have that tawdry cloak thrown on to his shoulders. But he had made a mistake: he ought to have accepted that ridiculous decoration with a grin as ridiculous. Now he tried to recapture the belated inanity.

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:The constable returned furtively to his shelter beneath the arch, hitched himself thoughtfully, and found half a cigarette inside his waistcoat pocket."I suppose you will want to know something about the way the Japanese women dress. I'll try to tell you; but if I make any mistakes, you must remember that I have not had much practice in describing ladies' apparel.
