TWO:"Hi! that ought to cook his dough!--with her face--and her voice!"How do I guess it is warm or cold? I feel it. Tell me.

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:Very well. I engage you from to-day. There is a good deal to do this morning. If you are ready we will begin at once.Hm! I wonder if youd have thought that if you had been the purchaser.
  • 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:In a secluded north-and-south road he looked back and beckoned me to his side: "You saw Major Harper's brother land safe and sound, you say? He told you this morning he is acquainted with your mother, eh; but not how?"When I said I would try she looked distressfully unassured and I added "I'll do whatever risks no life but mine."

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

THREE:Kind of you, remarked Charles. My{95} sister designed and cut a book-plate for him, sir.I had not. Her driver gathered the reins and I drew back.
  • 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:At the first opportunity our friends paid a visit to the Chinese part of Shanghai. They found a man at the gate of the city who was ready to serve them as guide, and so they engaged him without delay. He led them through one of the principal streets, which would have been only a narrow lane or alley in America; and they had an opportunity of studying the peculiarities of the people as they had studied in the Japanese cities the people of Japan. Here is what Frank wrote down concerning his first promenade in a Chinese city:"Yes," I guilefully replied, "I came with him."

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