TWO:The daughter must be the girl who was talking to him now. She sat on a little stool by the fire, and had brought out some sewing."By my faith! my lord," said Richard eagerly, "these knaves will not be trifled with; but lo! who have we here?" as he perceived a single horseman gallop forward from the centre.

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:or:
  • 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:"What a dear little creature!""Yes," cried Holgrave, starting up eagerly, "if the court-rolls are burned, who can claim the bondman?"

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

THREE:"I don't often come here," she said"this is a bit too classy for me. I go mostly to the coffee stalls down by the harbour. You mustn't think as I'm coining money at this, you know. I work mostly among the[Pg 403] fishermen, and they're a seedy lot. I started up town, but I'm not so young as I was, and sometimes even at the harbour I find it unaccountable hard to git off.""Yes I am. I'll go down and talk to him at the bend, and you can creep along and watch us through the hedge; and I'll shut my eyes and maybe part my lips, and he'll kiss me, you see if he don't."
  • 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:He then wandered about with a look of still deeper despondence, till the trampling of the returning horses sent a transient tinge across his cheek. He followed Roland's attendants, and again entered the court-yard. By some chance, as the young rider was alighting, his eye fell on the dejected stranger, who was standing at a little distance fixing an anxious gaze upon the heir.

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