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:Proceeding from these premises, the first thing should be to examine the action of existing valve gear, to determine where this want of the dead-stroke function can best be supplied, and to gain the aid of such suggestions as existing mechanism may offer, also to see how far the appliances in use may become a part of any new arrangement.
  • 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:"I never want another woman like you to deal with," he said. "I prefer a man, however great a scoundrel he may be. But you would have robbed me; I have turned the tables on you. And I am going to squeeze you. Give me those diamonds, take a receipt for the sum I mentioned, and I wait a fortnight."Before leaving we went back to the hotel for breakfast. Thereit was a first-class hotelthey gave us an apology for coffee, without milk or sugar, and two flimsy pieces of bread, as hard as wood and as black as shoe-polish. I was intensely hungry, and as nowhere at Charleroi anything else could be had, I did my best with the wooden bread and succeeded in washing it down with much chewing and jawing. But the sweet, hard stuff did not suit my digestion, and I felt ill already when at six o'clock we got into the motor-car and left for Dinant.

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

THREE:Prout looked keenly around him. He opened the back door into a yard that gave on to a lane at the back of the house. The bricks were damp and mossy, and on them was something that looked like the print of wheels. The door leading to the lane was wide, and on the edge on both sides something patchy glistened. Prout touched it with his fingers.
  • 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:The speaker asked the question quite fiercely.

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