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:He despised himself for feeling such intense annoyance. It was extraordinary how, as one grew older, it became less possible to restrain primitive and savage impulses. When things went wrong, you wanted to do something violent and unforgivable, something that you would regret afterwards, but which you would be quite willing to do for the sake of immediate satisfaction. As he approached the pavilion, he wanted to charge into the little group of players gathered around the scoring tablehe wanted to rush at them and clump their heads with his bat. His mind was so full of the ridiculous impulse that his body actually jolted forward as though to carry it out, and he stumbled slightly. It was absurd to feel like this, every little incident pricking him to the point of exasperation, everything magnified and translated into a conspiracy against him. Someone was manipulating the metal figure plates on the black index board. He saw a "1" hung up for the last player. Surely he had made more than One! All that swiping and thwacking, all that anxiety and suspense, and nothing to show for it! But, he re[Pg 4]membered, he had only scored once, and that had been a lucky scramble. The fielders had been tantalisingly alert. They had always been just exactly where he had thought they were not.Too muchee culio; allee same gong
  • 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:Black, dark, deserted, grimy shuttered windows--a suggestion of creeping mystery about it. Time ago the Corner House was the centre of what might have been a thrilling tragedy. Some of the older neighbours could tell of a cry in the night, of the tramping of feet, of a beautiful woman with the poison still in her hand, of the stern, dark husband who said never a word, though the shadow of the scaffold lay heavily upon him.At this moment the steward rang the preparatory bell for dinner, and[Pg 52] the conversation ended. Half an hour later dinner was on the table, and the passengers sat down to it.

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

THREE:So far as the Clockwork man's features were capable of change, there passed across them a faint expression of triumph and satisfaction. "I perceive," he remarked, "that I have indeed lapsed into a world of curiously insufficient and inefficent beings. I have fallen amongst the Unclocked. They cannot perceive Nowhere. They do not understand Nowhen. They lack senses and move about on a single plane. Henceforth, I shall act with greater confidence."
  • 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:"Good-morning," he responded, tardily and grimly. "Well, you air in a hurry."
