TWO:"You have made him a freeman since then?" inquired Sir Robert.

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:"Is he dead?" asked Reuben.In the month of August, in the year thirteen hundred and seventy-four, this distinguished place, called Sudley Castle, presented an interesting scenethe then owner, in consequence of his father's death, holding his first court for receiving the homage and fealty of his vassals.
  • 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:"Woman!" interrupted De Boteler impatiently, "your son has answered for himselfretire.""NaunI'm thinking."

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

THREE:Reuben was going through a new experience. For the first time in his life he had fallen under the dominion of a personality. From his boyhood he had been enslaved by an idea, but people, in anything except their relation to that idea, had never influenced him. Now for the first time he had a life outside Boarzell, an interest, a set of thoughts, which were not only apart from Boarzell but antagonistic to it.
  • 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:It made her blood boil to think of Robert and Albert in their exile. Robert had now been released from gaol, and had been sent by a charitable society to Australia. Reuben had refused to move a hand to help him. As for Albert, a few months ago a piteous letter had arrived, begging for money. He had, through Mr. Hedges, found work on a small Radical paper which soon came to grief, and since then had been practically starving, having had no success as a freelance. A friend of his wanted to start a weekly reviewTory this time, for Albert's politics were subservient to occasionand only required funds. Did Reuben feel prepared to make an investment? Thus poor Albert cloaked and trimmed his begging.
