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:It was late in the afternoon before Prout hit upon the trail he was looking for. He had been keeping the telegraph and the telephone busy. The scent was still hot, and it was just possible that he might come upon some trace of the missing notes before they left the country.
  • 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:An apprentice in entering the workshop should avoid everything tending to an appearance of fastidiousness, either of manner or dress; nothing is more repulsive to workmen, and it may be added, nothing is more out of place in a machine shop than to divide one's time between the work and an attempt to keep clean. An effort to keep as neat as the nature of the work will admit is at all times right, but to dress in clothing not appropriate, or to allow a fear of grease to interfere with the performance of work, is sure to provoke derision.

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

THREE:Near each staircase stood a blackboard on which the Germans had written that to go upstairs was prohibited under penalty of death. The Head explained that the Germans alleged that light signals had been given from the top storey.
  • 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 new teacher gathered round him a distinguished275 society, comprising not only professional philosophers, but also physicians, rhetors, senators, and statesmen. Among the last-mentioned class, Rogatianus, who filled the office of praetor, showed the sincerity of his conversion by renouncing the dignities of his position, surrendering his worldly possessions, limiting himself to the barest necessaries of life, and allowing himself to be dependent even for these on the hospitality of his friends. Thanks to this asceticism, he recovered the use of his hands and feet, which had before been completely crippled with gout.409
