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:"I'd like to do it," answered Lieut. Bigelow, "but I haven't the guard to spare. So many of my men got disabled that I won't have more than enough to guard the cars on the way back and keep these whelps from jumping the train or being rescued by their friends when we stop at the stations. The news of this affair is all over the country by this time, and their friends will all be out."Left alone, the tongues of the excited boys became loosened, and ran like the vibrations of a cicada's rattle.
  • 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:"It's a go," said the delighted boy. "I'm goin' to learn someway to write without bitin' my tongue, an' I'll write you as many words every day as I want catridges to shoot off, so that I'll have enough for the next Fourth o' July, and kill all old Pete Walker's snappin' dogs besides."In despair, the Deacon turned to a man who wore a Major's shoulder-straps.

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

THREE:The yells that soon rose from that thicket would have indicated that either a boy was being skinned alive or was having his face washed by his mother.
  • 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:"Col. Billings, some day I won't belong to the staff, and you won't have no shoulder-straps. Then I'll invite you to a little discussion, without no moderator in the chair."Si and Shorty started off with their long, easy campaign stride, which, in some incomprehensible way that the veteran only learns by practice, brought their feet down every time in exactly the right place, avoiding all stumbling-blocks, and covering without apparent effort a long distance in the course of an hour. The boys pattered industriously after, doing their best to keep up, but stumbling over roots and stones, and slipping on steep places, and dropping to the rear in spite of themselves.

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