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:But if the custody of the criminal class has been overrated as a preventive of crime, or regarded as the sole preventive instead of one amongst many, it does not follow that crime on that account must be left to itself. It only follows that we should trust to punishment less and to other agencies more in our war with[104] crime, and that we should seek to check the latter at its source, not in its full stream, by attending to the improvement of the general conditions of life. It is quite certain, for instance, that the spread of education, of which Beccaria wrote in terms of such despair, means the diminution of crime; and as the majority of crimes are committed between the ages of twenty and forty, it may be predicted that from the present year onwards the great Act of 1870 will bear increasing fruit in lowering our criminal statistics. More too may be hoped for from the electric light than from any multiplication of prisons.
  • 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 aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.

THREE:Capital punishment becomes a spectacle for the majority of mankind, and a subject for compassion and abhorrence for others; the minds of the spectators are more filled with these feelings than with the wholesome terror the law pretends to inspire. But in moderate and continuing penalties the latter is the predominant feeling, because it is the only one. The limit, which the legislator should affix to the severity of penalties, appears to lie in the first signs of a feeling[173] of compassion becoming uppermost in the minds of the spectators, when they look upon the punishment rather as their own than as that of the criminal.What can be thought of an author who presumes to establish his system on the dbris of all hitherto accepted notions, who to accredit it condemns all civilised nations, and who spares neither systems of law, nor magistrates, nor lawyers?
  • 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:From this we see how useful is the art of printing, which makes the public, and not a few individuals, the guardians of the sacred laws, and which has scattered that dark spirit of cabal and intrigue, destined to disappear before knowledge and the sciences, which, however apparently despised, are in reality feared by those that follow in their wake. This is the reason that we see in Europe the diminution of those atrocious crimes that afflicted our ancestors and rendered them by turns tyrants or slaves. Whoever knows the history of two or three centuries ago and of our own, can see that from the lap of luxury and effeminacy have sprung the most pleasing of all human virtues, humanity, charity, and the toleration of human errors; he will know what have been the results of that which is so wrongly called old-fashioned simplicity and honesty. Humanity groaning under implacable superstition; the avarice and ambition of a few dyeing with human blood the golden chests and thrones of[132] kings; secret assassinations and public massacres; every noble a tyrant to the people; the ministers of the Gospel truth polluting with blood hands that every day came in contact with the God of mercythese are not the works of this enlightened age, which some, however, call corrupt.It would appear at first sight that there could be[71] little to say about crimes and punishments, so obvious and self-evident seem the relations that exist between them. Many people still believe in an innate sense of justice in mankind, sufficient always to prevent wide aberrations from equity. Is it, they might ask, conceivable that men should ever lose sight of the distinction between the punishment of guilt and the punishment of innocence?that they should ever punish one equally with the other? Yet there is no country in the world which in its past or present history has not involved the relations of a criminal in the punishment inflicted on him; and in savage countries generally it is still common to satisfy justice with vengeance on some blood-relation of a malefactor who escapes from the punishment due to his crime.
