TWO:"Ah, he is, I doubt not, but the burnt-out ruin of what he was half a year ago. You perceive, he has not succeeded; he has not devoured her; actually she has turned his fangs upon himself and has defeated his designs toward her as if by magic. And yet the only magic has been her vigilance, her courage, her sagacity. Smith,"--again he stroked the mane of his charger--"if I tell you--"The Doctor removed his hat as though in honour of the mere mention of his visitor. "Did you give her my love?" was his light rejoinder, hat still poised at an elegant angle.

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:
  • 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 story of the coolie-trade and some of the conversation that followed cleared the mystery that surrounded the narrator and had given him the name by which he was known. He had been an active participant in the peculiar commerce of the East, which includes the violation of laws whenever they prove inconvenient, such as the smuggling of opium and the shipment of coolies to the countries where they are in demand. His latest venture was one that required considerable secrecy, as it involved the purchase of arms for the rebels in Japan. For this reason he had been very cautious in his movements around Yokohama and during his whole stay in Japan, and he had found it judicious to leave the country on the vessel that came so near being wrecked in the typhoon that overtook our friends. He was safely away from Japan now, and the arms that he had purchased for the rebels were in the hands of the government. He had made money by the operation, and was on the lookout for something new.

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

THREE:"Lovely evening," she remarked, presently.
  • 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:"What is it?" Fred asked.Mr Silverdale laughed gleefully.

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