TWO:While Si was going back the way he had come Shorty was tearing through the tangled brush, turning over the tree-tops by main strength, searching for Pete Skidmore. The rest of the company were seeking out the fallen ones hither and thither, and calling to one another, as they made discoveries, but Shorty only looked for Pete Skidmore. Si and Harry presently came to Gid Mackall's body, lying motionless in a pool of blood that dyed crimson the brown leaves thickly covering the ground. His cap had fallen off, and his head had crushed down into a bunch of slender oak twigs; his eyes were closed, and his callow face white as paper.Si trembled a httle, for fear that they had his father cornered. But the Deacon was equal to the emergency.

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:"Goodness," moaned some of the boys, as they were trying to obey what seemed a' hopeless mass of directions, "do we have to do this every mornin' before we kin have breakfast? We'll starve to death before we git anything to eat. No use tellin' us to draw our stomachs in. They're clean in to our backbones now."
  • 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 aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.

THREE:
  • 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 ain't one of 'em within cannon-shot, and won't be till we go out and hunt 'em up again. You've come near spilin' the spring with your tormented foolishness. What on earth possessed you to climb that boss? You need half killin', you do. Go up higher there and fill your canteens from where the water's clear. Be slow and careful, and don't rile the water. Say, I see some nice sassafras over there. I always drink sassafras tea this time o' year. It cleans the blood. I'm goin' over and see if I can't git a good root while you're fillin' your canteens."
