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:After the party had recovered from the fatigues of the journey to Fusiyama, the boys were on the lookout for something new. Various suggestions were made, and finally Frank proposed that they should go to a theatre. This was quite to Fred's liking, and so it did not take a long time to come to a determination on the subject. The Doctor agreed that the theatre was an interesting study, and so the matter was settled.

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

THREE:Her voice suddenly ceased again, as if a tap been turned off by some external agency, and Alice wisely made no reply of any kind, feeling sure that in a minute or two her mother would begin to give vent to that faint snoring which betokened that she had gone to sleep again. That did not interrupt the flow of her ecstatic musings, whereas her mothers general attitude to all the novel institutions which were so precious to her gave her a tendency to strong shudderings. Only half an hour ago Mrs Keeling had said that she was sure she saw nothing wrong in confession and{100} would not mind going herself if she could think of anything worth telling Mr Silverdale about.... Alice had drawn in her breath sharply when her mother said that, as if with a pang of spiritual toothache.The heaviness of my soul, by reacting upon my frame and counterfeiting sleep better than I could have done it in cold blood, saved me, I fancy, from death or a northern prison. When I guessed my three visitors were gone I stirred, as in slumber, a trifle nearer the window, and for some minutes lay with my face half buried in the pillow. So lying, there stole to my ear a footfall. My finger felt the trigger, my lids lifted alertly, and as alertly reclosed. Outside the window one of the officers, rising by some slender foothold, had been looking in upon me, and in sinking down again and turning away had snapped a twig. He glanced back just as I opened my eyes, but once more my head was in shadow and the moonlight between us. When I peeped again he was moving away.
  • 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.
