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: Whatever improvement our penal laws have undergone in the last hundred years is due primarily to Beccaria, and to an extent that has not always been recognised. Lord Mansfield is said never to have mentioned his name without a sign of respect. Romilly referred to him in the very first speech he delivered in the House of Commons on the subject of law reform. And there is no English writer of that day who, in treating of the criminal law, does not refer to Beccaria.
  • 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:Would you prevent crimes, contrive that the laws favour less different orders of citizens than each citizen in particular. Let men fear the laws and nothing but the laws. Would you prevent crimes, provide that reason and knowledge be more and more diffused. To conclude: the surest but most difficult method of making men better is by perfecting education.[20]

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

  • 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:Paley, of course, defended the thing he found established; nor, considering the system he had to defend, did he state the case for it without ingenuity. He had, indeed, nothing to add to what Blackstone had said regarding punishment, namely, that it was inflicted, not in proportion to the real guilt of an offence, but in proportion to its facility of commission and difficulty of detection. To steal from a shop was not more criminal than to steal from a house, but, as it was more difficult to detect, it was more severely punished. Sheep, horses, and cloth on bleaching-grounds were more exposed to thieves than other kinds of property; therefore their theft required a stronger deterrent penalty.There is an apparent discrepancy in Beccarias first condemning death as too severe a punishment and then recommending lifelong servitude as one of more deterrent power; but Beccaria would have said that the greater certainty of the latter more than compensated for the greater severity of the other. As regards the relative power of the two punishments, it probably varies in different individuals, some men having a greater dread of the one, and some of the other. The popular theory certainly goes too far, when it assumes that all men have a greater dread of the gallows than of anything else. When George III. once granted a pardon to the female convicts in Newgate on condition of their transportation to New South Wales, though seventeen of them accepted[39] the offer, there were yet six who preferred death to a removal from their native country. It is also stated by Howard that in Denmark the punishment in cases of infanticide, namely, imprisonment for life, with labour and an annual whipping on the place of the crime, was dreaded more than death, which it superseded as a punishment.
