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

THREE:The sun set, and Reuben had given up even the attempt to work. He wandered on Boarzell till the outline of its crest was lost in the black pit of night. Then a new anxiety began to fret him. Possibly all was going well since everybody said so, butsuppose the child was a girl! Up till now he had scarcely thought of such a thing, he had made sure that his child would be a boy, someone to help him in his struggle and to[Pg 84] reap the fruits of it after he was gone. But, suppose, after all, it should be a girl! Quite probably it would bewhy should he think it would not? The sweat stood on Reuben's forehead.She asked him a few questions about the lambing, then:
  • 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:Peter's strong frame and broad shoulders were shown off in all their glory by his tight blue coathe was spoiling for the fight, every now and then clenching his fists under the table, and dreaming of smart cuts and irresistible bashes. Albert thought of the pretty girls he would dance with, and the one he would choose to lead away into the rustling solitude of Boarzell when his father was not looking ... to lie where the gorse flowers would scatter on their faces, and her dress smell of the dead heather as he clasped her to him. Richard was inclined to sneer at these rustic flings, and to regret the westward pastures where Greek syntax and Anne[Pg 164] Bardon exalted life. Jemmy and George thought of nothing but the swings and merry-go-rounds; Tilly and Caro did not think at all, but wondered. Reuben watched their big eyes, so different from the boys', Tilly's very blue, Caro's very brown, and felt relieved when he looked from them to their grandmother, sitting stiffly in a patched survival of the widow's dress, her knotted hands before her on the table, at once too indifferent and too devoted to pity the questing youth of these two girls."It is only a stranger," said Margaret, answering to Lucy's glance, "whom Stephen has promised to shelter.You need not fear."
