TWO:Certainly no cricket ever dropped blither music from his legs than did my beautiful horse that glorious morning as we clattered in perfect rhythm on the hard clean road of the wide pine forest. Ah! the forest is not there now; the lumbermen--I galloped away filled with an absurd foreboding that he was too sure, which may have come wholly from my bad temper at being started too late to see our ladies before morning. However, at two that night, my saddle laid under my head, and haversack under the saddle, I fell asleep with all Gallatin for my bedchamber, the courthouse square for my bed, the sky for my tester, the pole-star for my taper, hogs for mosquitoes and a club for a fan.

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:"Ah, Richard, in there the war is all over.""How very convenient that is!" said Frank; "you don't have to carry money around with you, but get it when and where you want it."
  • 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:"As to the jin-riki-sha," he continued, "my experience with it in my last visit to Japan since its introduction gives me a high opinion of the Japanese power of endurance. A few days after my arrival, I had occasion to go a distance of about forty miles on the great road along the coast,[Pg 111] from Yokohama to Odiwara. I had three men to draw the carriage, and the journey was made in twelve hours, with three halts of fifteen minutes each. You could not have done better than this with a horse and carriage in place of the man-power vehicle. On another occasion I went from Osaka to Nara, a distance of thirty miles, between ten in the morning and five in the afternoon, and halted an hour for lunch at a Japanese inn on the road. Part of the way the road was through fields, where it was necessary to go slowly, and quite frequently the men were obliged to lift the vehicle over water-courses and gullies, and a good deal of time was lost by these detentions."

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

THREE:But now came raptures and rhapsodies over the opened letters. Ferry's orders had not been expected to reach him to-night, Gholson said, and so we insisted they and my letter should remain in the saddle-pockets while Gholson ate, and while the good news, public and personal, of the Harpers' letters went round.
  • 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).
