TWO:He was not wordy, and he tarried but a moment, yet he explained his paralysis. In the dreary monotone of a chronic sour temper he related that some Confederates, about a year before, had come here impressing horses, and their officer, on being called by him "no gentleman," had struck him behind the ear with the butt of a carbine. I asked what punishment the officer received, and I noticed the plural pronoun as he icily replied, "We didn't enter any complaint."At that moment there was nothing in the world for him but she.

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:She could not improve on that either for silliness or pathetic sincerity, and unable to contemplate the delay which the post would entail, she gave it to the boy covered with buttons to carry it at once by hand to the Vicarage and wait for an answer. That would take half an hour: there were thirty delicious minutes of suspense, for though she did not doubt the purport of his answer, it was thrilling to have to wait for it.{217}
  • 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:Frank was looking through the captain's glass at the persons who were moving about the deck of the bark. Suddenly he observed something and called out to his companions:

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

THREE:"Because," was the reply, "they want to keep the cable straight while they are braiding it. As fast as they braid it it hangs down by its own weight, and coils on the ground beneath. No expensive machinery is needed, and the principal labor in the business is to carry the bamboo fibre to the platform where it is wanted. This cable is very strong and cheap, and takes the place of hemp rope in a great many ways. It is larger and rougher than a hempen rope of the same strength, but the Chinese are willing to sacrifice beauty for cheapness in the majority of practical things."
  • 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:Mr Keeling passed him this latest acquisition.

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