TWO:I was in despair; our horses had caught our frenzy and were plunging to be after their fellows, and a fresh body of the enemy were hurtling into the grove. Dropping my burden I vaulted up, and we scurried away, saved only by the enemy's healthy fear of an ambush. The first man we came up with was Quinn, with the rear-guard. "Is he dead?" he growled.

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."[Pg 74]
  • 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:The steamer was anchored nearly half a mile from shore. English, French, German, and other ships were in the harbor; tenders and steam-launches were moving about; row-boats were coming and going; and, altogether, the port of Yokohama presented a lively appearance. Shoreward the picture was interesting. At the water's edge there was a stone quay or embankment, with two inner harbors, where small boats might[Pg 80] enter and find shelter from occasional storms. This quay was the front of a street where carriages and pedestrians were moving back and forth. The farther side of the street was a row of buildings, and as nearly every one of these buildings had a yard in front filled with shade-trees, the effect was pretty.

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

THREE:These runners are in the employ of the men who supply live fish for the tables of those who live at a distance from the sea or from the lakes, and are willing to pay for the luxury. A runner stands waiting, and the instant the fish is in his charge he is off. If the distance is great, there are relays of men stationed along the route; and so the precious merchandise goes forward from one to the other without a moment's delay. Only the wealthy can afford this mode of transporting fish, as the cost is often very heavy. Some of the princes, in the olden time, were in the habit of eating fresh fish at their tables every day that had been brought in this way for a hundred and fifty miles. Great quantities of fish are still carried in this primitive manner, but not for such long distances as formerly. Many fish are transported on horseback, in barrels of water; but the most delicate and valuable are borne only on the shoulders of men, as the jolting of a horse will soon kill them.LVI H?TEL DES INVALIDES
