TWO:She reloaded for him, and fired from time to time herself, and he moved from the little round hole in the wall to one in the window blind, in the feeble, the faithless hope that the Indians might perhaps be deceived, might fancy that there was more than the one forsaken man fighting with unavailing courage for the quiet woman who stayed close by his side, and for the two children, huddled whimpering in one corner, their little trembling arms clasped round each other's necks.

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 beautiful part of it, to Sandy, was that he could sit by and watch, do nothing, except pay out rope and let them tie themselves up in it.Taking an arm of each, Sandy led them, wordless, up the path.

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

THREE:Jeff explained. He had sent a radiogram to the yacht, and as its owner had already sent one identifying Jeff, he was given the information that the real necklace was being brought back, extra heavily insured in a London company, by the captain himself.Landor recalled the twenty years of all winter campaigns, dry camps, forced marches, short rations, and long vigils and other annoyances that are not put down in the tactics, and smiled again, with a deep cynicism. Barnwell sat silent. He sympathized with Stone because his interests lay that way, but he was somewhat unfortunately placed between the military devil and the political deep sea.
  • 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.
