TWO:The Elltons' pretty child was like its mother, [Pg 288]gentler and more caressing. It lay placidly in her arms and patted her lips when she tried to talk, with the tips of its rosy fingers. She caught them between her teeth and mumbled them, and the child chuckled gleefully. But by and by it was taken away to bed, and then Felipa was alone with its father and mother. Through the tiresome evening she felt oppressed and angrily nervous. The Elltons had always affected her so.

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:He rode beside Mrs. Landor along the road in the ravine bed, and the soldiers followed some twenty yards in the rear. They were making as much haste as was wise at the outset, and Felipa bent forward against the ever rising wind, as her horse loped steadily on.
  • 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:It was not very dark. The sky was thick with clouds, but there was a waning moon behind them. The only light in the garrison was in the grated windows of the guard-house.The advance guard advanced less and less. Half drunk and ever drinking, in quaking fear of the timber, it kept falling back.
  • 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:The men came running. They had scanned the place by the wharf, and, satisfied that no one lurked there and that the tender was secure, they had gone further along the inlet coast.

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