TWO:It having come to my attention that the process of metals shipment is in danger because of a threat to the materials and procurement divisions of AMP, Ltd., I wish to advise you, as current Chairman of the Board, of the nature of the emergency, and request your aid in drawing up plans to deal with it.

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:Hours before the train was due Maria had Abraham Lincoln bring out the spring-wagon and hitch the horses to it. Then he had to lay in a bed of clean straw, and upon this was placed a soft feather bed, blankets and pillows. Maria decided that she would drive to the station herself.
  • 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:CHAPTER XX. AFTER THE SKIRMISH"That's so," said Jake Humphreys. "I don't think any of us is in shape to throw up anything to another about shaking. I own up that I was never so scared in all my life, and I feel now as if I ought to get down on my knees before everybody, and thank God Almighty that my life was spared. I ain't ashamed to say so."

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

THREE:Then the great problem became one of proper food for the boys. Daily the rations were growing shorter in Chattanooga, and if they had been plentiful they were not suited to the delicate stomachs of those seriously ill. Si was slowly improving, but the Deacon felt that the thing necessary to carry him over the breakers and land him safely on the shores of recovery was nourishing food that he could relish.
  • 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:

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