TWO:"Hello, Alf," said Si delightedly. "I'm so glad to see you. I've bin huntin' everywhere for you. What's happened to you? Badly hurt?""There's more than 3D tapes," the squat man said, and grinned.

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:So he cooked as good a breakfast for the boys as he could prepare from his materials, woke up Shorty and put him in charge, and an hour before daybreak turned the horse's head toward the pontoon bridge, and started him on a lively trot.
  • 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:"Git your guns and fall in two ranks on that sod, there, at once," commanded Si, in quick, curt accents.

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

THREE:"Well," answered Bob, with a gulp, "let me go along, then, as a CorporalI'll change my blouse and borrow a Corporal's"
  • 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:There was a rush of infuriated men, which carried Shorty over and made him the object of a storm of blows and kicks. So many piled on him at once that they struck and kicked one another in their confusion. The door was torn out, and its pieces fell with the tumble of cursing, striking, kicking men that rolled outside.

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