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:Pederasty, so severely punished by the laws, and so readily subjected to the tortures that triumph over innocence, is founded less on the necessities of man, when living in a state of isolation and freedom, than on his passions when living in a state of society and slavery. It derives its force not so much from satiety of pleasure as from the system of education now in vogue, which, beginning by making men useless to themselves in order to make them useful to others, causes, by its too strict seclusion, a waste of all vigorous development, and accelerates the approach of old age.
  • 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 close connection, therefore, of crime and punishment is of the utmost importance, if it be desirable that in rough and common minds there should, together with the seductive idea of an advantageous crime, immediately start up the associated idea of its punishment. Long delay has no other effect than the perpetual separation of these two ideas; and whatever the impression produced by the punishment of a crime, it produces it less as a punishment than as a sight, and only produces it when the horror of the particular crime, which would serve to strengthen the feeling of the punishment, has been weakened in the minds of the spectators.

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

THREE:But, in spite of the liberalism of the Count, the penal laws and customs of Lombardy remained the same; and the cruel legal procedure by torture existed still, untouched by the salutary reforms effected in other departments of the Government. There was the preparatory torture, to extort confession from criminals not yet condemned; there was torture for the discovery of a criminals accomplices; and there was the extraordinary or greater torture, which preceded the execution of a sentence of death. It is true that torture could only be applied to crimes of a capital nature, but there was scarcely an act in the possible category of crimes that was not then punishable with death. Proofs of guilt were sought almost entirely from torture and secret accusations, whilst penalties depended less on the text of any known law than on the discretionthat is, on the capriceof the magistrate.DAlembert, Diderot, Helvetius, Buffon, Hume, illustrious names, which no one can hear without emotion! Your immortal works are my continual study, the object of my occupation by day, of my meditation in the silence of night. Full of the truth which you teach, how could I ever have burned incense to worshipped error, or debased myself to lie to posterity? I find myself rewarded beyond my hopes[6] in the signs of esteem I have received from these celebrated persons, my masters. Convey to each of these, I pray you, my most humble thanks, and assure them that I feel for them that profound and true respect which a feeling soul entertains for truth and virtue.
  • 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.
