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:Behind his paper Prout gave a start. Here was a case where the pursuit of one crime led to another. The leader of the gang of thieves had large orange coloured freckles on his hand the same as Prout had seen on the hands of the victim of the Corner House tragedy.
  • 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 Lige people were already up and about, and wandered through the streets full of fear, for all sorts of rumours were heardthat civilians were murdered, the town was to be burned down, and that a start would be made very soon. As they looked at those burning hamlets yonder they believed the rumours, and went nearly mad for fear; the men as well as the women could not help46 themselves, and wept. During the night various posters were stuck on the walls about military action. The following is the translation of one of these:

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

THREE:Artistic drawing is addressed to the senses, geometrical drawing is addressed to the understanding. Geometrical drawing may, however, include artistic skill not in the way of ornamentation, but to convey an impression of neatness and completeness, that has by common custom been assumed among engineers, and which conveys to the mind an idea of competent construction in the drawing itself, as well as of the machinery which is represented. Artistic effect, so far as admissible in mechanical drawing, is easy to learn, and should be understood, yet through a desire to make pictures, a beginner is often led to neglect that which is more important in the way of accuracy and arrangement.
  • 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:They constantly heard the boom, boom of the shells exploding near by, and each time thought that their last hour had struck. The gloomy cellar depressed them still more, and nobody really believed that there was any chance of being saved. So the44 little sisters prayed on, preparing each other for death, and looking for the approaching end in quiet resignation.On August 12th I came for the first time to Tongres. They had been there only a few days, and only near the town-hall did I see a goodly number of the garrison. Many wounded were brought there, and carried in through the door under the outside stairway. They came from Haelen, where a battle was being fought that afternoon and for which they had left in the morning. For the attack on the entrenched Belgians they had used cavalry exclusively, who were simply mowed down by the murderous fire from the hidden mitrailleuses and the infantry fire from the trenches. The Germans suffered a great reverse, and were deeply embittered.
