TWO:Laws should only be considered as a means of conducting mankind to the greatest happiness.

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:[19]
  • 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 voice of a philosopher is too feeble against the noise and cries of so many followers of blind custom, but the few wise men scattered over the face of the earth will respond to me from their inmost hearts; and, amid the many obstacles that keep it from a monarch, should truth perchance arrive in spite of him at his throne, let him know that it comes there attended by the secret wishes of all men; let him know that before his praises the bloody fame of conquerors will be silenced, and that posterity, which is just, will assign him the foremost place among the pacific triumphs of a Titus, an Antonine, or a Trajan. Palpable but consecrated abuses, which in many nations are the necessary results of a weak political constitution, are Secret Accusations. For they render men false and reserved, and whoever may suspect that he sees in his neighbour an informer will see in him an enemy. Men then come to mask their real feelings, and by the habit of hiding them from others they at last get to hide them from themselves. Unhappy they who have come to that; who, without clear and fixed principles to guide them, wander lost and confused in the vast sea of opinions, ever busied in saving themselves from the horrors that oppress them, with the present moment ever embittered by the uncertainty of the future, and without the lasting pleasures of quiet and security, devouring in unseemly haste those few pleasures, which occur at rare intervals in their melancholy lives and scarcely console them for the fact of having lived! Is it of such men we can hope to make intrepid soldiers, defenders of their country and crown? Is it among such men we shall find incorrupt magistrates, able with their free and patriotic eloquence to sustain and develop the true interests of their sovereign, ready, with the tribute they bear, to[143] carry to the throne the love and blessings of all classes of men, and thence to bring back to palaces and cottages alike peace and security, and that active hope of ameliorating their lot which is so useful a leaven, nay, which is the life of States?

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

THREE: There remain two questions for me to examine: the first, whether asylums of refuge are just, and whether international agreements of extradition are expedient or not. There should be no spot within the boundaries of any country independent of the laws. Every citizen should be followed by their power, as every substance is followed by its shadow. There is only a difference of degree between impunity and the right of asylum; and as the effective influence of punishment consists more in its inevitability than in its violence, asylums do more to invite to crimes than punishments do to deter from them. The multiplication of asylums is the formation of so many petty sovereignties; for where there are no laws to command, there it is easy for new laws, opposed to the general laws of a country, to be formed, and consequently for a spirit opposed to that of the whole collective social body to arise. All history shows that from asylums have issued great revolutions in States and in the opinions of mankind.
  • 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.
