TWO:Careful milker that he was, he did not stop until he had stripped the last drop, and the cow, knowing at once that a master hand was at her udder, willingly yielded all her store.This is the same as before the fighting. It is always the same. A master is a master.

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 Alberts were shunted off without trouble. Albin, heaving a small sigh, fixed the details of his next job in his mind: quality control in a smelting process. It took him a few seconds to calm down and get ready, and then he headed for room six, where one Albert waited for him, trying to think only of the job ahead, and not at all of the party, of Dr. Haenlingen, of Johnny Dodd, of rebellion and war.Presently, on mounting a roll of the ground, they saw sloping down from them a few rods away, and running obliquely to their right, a small "deadening," made by the shiftless farmer for his scanty corn crop. A mob of fugitives flying through had trampled the stalks to the ground. Si and Shorty had seen some of them and yelled at them to come up and form on them, but the skedaddlers either would not or could not hear.

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

THREE:"And didn't I shoot one, too?" put in Gid Mackall. "Just as much as you did. They want tall men in the company, don't they, Corpril? Not little runts."
  • 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.
