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:Bruce bowed. He knew that he had done a foolish thing in betraying the fact that Hetty had sent for him. And her message would not have been in the nature of a prayer had not the need been urgent.
  • 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:Leona smiled in a queer, strange way."Precisely. But not quite in the way you imagine. Directly Maitrank saw those deeds he knew exactly what had happened. But that wonderful man did not betray himself. His confidential secretary told me that he never turned a hair. He simply regretted that he had no spare capital; he got a warrant for your arrest, and he will be in London tomorrow morning."

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

THREE:Hetty ceased to speak for a moment. The recollection of what she had gone through overcame her. Bruce kissed her tenderly.We have also to consider in what relation the new193 Scepticism stood to the new Platonism by which, in common with every other school, it was eventually either displaced or absorbed. The answer usually given to this question is that the one was a reaction from the other. It is said that philosophy, in despair of being able to discover truth by reason, took refuge in the doctrine that it could be attained by supernatural revelation; and that this doctrine is the characteristic mark distinguishing the system of Plotinus from its predecessors. That a belief in the possibility of receiving divine communications was widely diffused during the last centuries of polytheism is, no doubt, established, but that it ever formed more than an adjunct to Neo-Platonism seems questionable; and there is no evidence that we are aware of to show that it was occasioned by a reaction from Scepticism. As a defence against the arguments of Pyrrho and his successors, it would, in truth, have been quite unavailing; for whatever objections applied to mens natural perceptions, would have applied with still greater force to the alleged supernatural revelation. Moreover, the mystical element of Neo-Platonism appears only in its consummationin the ultimate union of the individual soul with the absolute One; the rest of the system being reasoned out in accordance with the ordinary laws of logic, and in apparent disregard of the Sceptical attacks on their validity.
  • 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:I found sailors also in Brussels, but for the rest there was only a little military display there. In this town reigned a certain oppressive silence and157 the cafs were not much frequented. The Brussels people did not hide their patriotic sentiments, and nearly every house displayed the Belgian flag, thanks chiefly to the strong attitude of Burgomaster Max. Outwardly Brussels had not suffered by the war; not a house was damaged and nobody had been killed yet. Nor was there lack of provisions, as was proved by the fact that at the "Mtropole," one of the largest restaurants, I paid only seventy-five centimes (sevenpence-halfpenny) for bread, cold beef, and pickles.
