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:CHAPTER XX. CERTAINTY OF PUNISHMENTSPARDONS.This, then, is the way to avoid confounding the relations and invariable nature of things, which, being unlimited by time and in ceaseless operation, confounds and overturns all narrow regulations that depart from it. It is not only the arts of taste and pleasure which have for their universal principle the faithful imitation of nature; but the art of politics itself, at least that which is true and permanent, is subject to this general maxim, since it consists in nothing else than the art of directing in the best way and to the same purposes the immutable sentiments of mankind.
  • 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: From the simple consideration of the truths hitherto demonstrated it is evident that the object of punishment is neither to torment and inflict a sensitive creature nor to undo a crime already committed. Can he, whose function it is, so far from acting from passion, to tranquillise the private passions of his fellows, harbour in the body politic such useless cruelty, the instrument either of furious fanatics or of weak tyrants? Shall perchance the shrieks of an unhappy wretch call back from never-receding time actions already executed? The object, therefore, of punishment is simply to prevent the criminal from injuring anew his fellow-citizens, and to deter others from committing similar injuries; and those punishments and that method of inflicting them should be preferred which, duly proportioned to the offence, will produce a more efficacious and lasting impression on the[166] minds of men and inflict the least torture on the body of a criminal.It would also seem to demand no great insight to perceive that a voluntary intention must be a universal attribute of a criminal action. No one would think of punishing a man who in his sleep killed another, although, if the injury to society be the measure of punishment, his crime is equivalent to intentional homicide. Yet at Athens an involuntary murderer was banished until he could, give satisfaction to the relatives of the deceased; and in China, though the penal code generally separates intentional from accidental crimes, anyone who kills a near relation by accident or commits certain kinds[72] of arson by accident undergoes different degrees of banishment and a fixed number of bamboo strokes.[40]

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

THREE:There are a few obvious remedies by which the inducements to crime might be easily diminished. In 1808 Sir Samuel Romilly brought in a bill, to provide persons tried and acquitted of felony with compensation, at the discretion of the judge, for the loss they incurred by their detention and trial. This was objected to, on the ground that the payment of such compensation out of the county rates would discourage prosecutions; and the only justice done to men falsely accused from that day to this is the authorisation given to goal-governors in 1878 to provide prisoners, who have been brought from another county for trial at the assizes and have been acquitted, with means of returning to their own homes. Something more than this is required to save a man so situated from falling into real crime.
  • 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:The treatise Dei Delitti, instead of throwing any light on the subject of crimes, or on the manner in which they should be punished, tends to establish a system of the most dangerous and novel ideas, which, if adopted, would go so far as to overturn laws received hitherto by the greater part of all civilised nations.
