TWO:The moon was standing round and bright in a sky gemmed with stars, and, as the rover had just said, her beams fell unshadowed upon the open space where the roads met;and here, directly in the centre, two dark figures were revealed. One was kneeling, while the other stood erect, holding at arm's length a cross. The galleyman gasped for breath as he drew closer to his companions, who, concealed in the shade of the hedge, looked eagerly at the objects of their alarm.

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:"Oh Lord!" wailed Ditch"Oh Lord!""Baron de Boteler, I have not willingly obtruded myself. The duty of affording counsel to this unfortunate man impelled me to enter thus once again. Stephen Holgrave must choose the bondage, because he would live for his wife and his yet unborn child; but, ere he resigns his freedom, he would stipulate for his offspring being exempt from the bond of slavery."
  • 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:"Perhaps you will be out of it some day."So Albert's letter remained unansweredCaro felt that Reuben was unjust. She had grown very critical of him lately, and a smarting dislike coloured her [Pg 337]judgments. After all, it was he who had driven everybody to whatever it was that had disgraced him. He was to blame for Robert's theft, for Albert's treachery, for Richard's base dependence on the Bardons, for George's death, for Benjamin's disappearance, for Tilly's marriage, for Rose's elopementit was a heavy load, but Caro put the whole of it on Reuben's shoulders, and added, moreover, the tragedy of her own warped life. He was a tyrant, who sucked his children's blood, and cursed them when they succeeded in breaking free.

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:Albert sat upthen asked for some water.

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