TWO:CHAPTER III. CONSEQUENCES.

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:
  • 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:It would, therefore, be a mistake to ascribe to one, who only discusses social conventions and their consequences, principles contrary either to natural law or to revelation, for the reason that he does not discuss them. It would be a mistake, when he speaks of a state of war as anterior to a state of society, to understand it in the sense of Hobbes, as meaning that no obligation nor duty is prior to the existence of society, instead of understanding it as a fact due to the corruption of human nature and the want of any expressed sanction. It would be a mistake to impute it as a fault to a writer who is considering the results of the social compact[115] that he does not admit them as pre-existent to the formation of the compact itself.In such a zigzag path has our penal legislation been feeling, and is still feeling, its way, with evident misgiving of that principle of repression, as false as it is old, that an increase of crime can only be met by an increase of punishment.

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

THREE:In order that a punishment may attain its object, it is enough if the evil of the punishment exceeds the advantage of the crime, and in this excess of evil the certainty of punishment and the loss of the possible advantage from the crime ought to be considered as part; all beyond this is superfluous and consequently tyrannical. Men regulate their conduct by the reiterated impression of evils they know, not by reason of evils they ignore. Given two nations, in one of which, in the scale of punishments proportioned[167] to the scale of crimes, the severest penalty is perpetual servitude, and in the other the wheel; I say that the former will have as great a dread of its severest punishment as the latter will have; and if there be any reason for transporting to the former country the greater penalties of the other, the same reasoning will serve for increasing still more the penalties of this latter country, passing imperceptibly from the wheel to the slowest and most elaborate tortures, nay, even to the last refinements of that science which tyrants understand only too well.
  • 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:Such was legal opinion generally as expressed by its ablest representatives with respect to the due punishment for pocket-picking not a hundred years ago. It is easy now to smile at such errors, and, at the barren waste of wisdom spent in their defence, but what weight after that can be attached, on subjects of the general policy of the law, to the opinion of its chief professors? Can it be too much regretted that Lord Chief Justice Ellenborough should have sacrificed to his own authority, whilst alive, the authority of all judges ever destined to succeed him?CHAPTER XIII.
