TWO:The rest was lost to me, for the men crowded round the innkeeper, who now aired his knowledge about the occurrence and evidently spoke with true conviction. At the end of the conversation they took their tankards from the bar, and shouted and cried: "Ah, well, if that is so, vive la Hollande! vive la Belgique! vive notre roi!" Suddenly we were the best of friends.

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 chafed under the flippancy. He was quite undecided what to do. Beyond all question the patient whom he had attended under such mysterious circumstances was the murdered man. Was it his duty at once to go to the police and tell them all he knew? On the other hand he had no desire to violate professional confidence. Certainly the lovely Spaniard and the people of the house could have nothing to do with the murder. If they had, they would never have called in a doctor's aid and paid him a handsome fee to save the life of that poor dissipated wretch. It must have happened after they had gone.
  • 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 aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.

THREE:The lesser is the greaters enemy,
  • 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:Meanwhile the strength of the analytical method was doubled by its extension to the phenomena of growth and change; for, as applied to these, it became the famous theory of Development or Evolution. No idea belongs so completely to modern philosophy; for even the ancient thinkers who threw their cosmology into a historical form had never attempted to explain the present by the past. If anything, they explained the past by the present, assuming a rough analogy to exist between the formation of the universe as a whole and the genesis of those natural or artificial bodies which were continually growing or being built up before their eyes. Their cosmology was, in fact, nothing but the old mythology stripped of its personal or conscious element; and, like it, was a hypothesis unsupported by any external evidence;a criticism not inconsistent with the admission that to eliminate the supernatural element from speculation was, even in the absence of any solid addition to human knowledge, an achievement of inestimable value. The evolutionary method is also an elimination of the supernatural, but it is a great deal more. By tracing the history of compound structures to their first origin, and noting the successive increments to which their gradual growth is due, it reveals, as no statical analysis ever could, the actual order of synthesis, and the meaning of the separate constituents by whose joint action their movements are determined; while, conversely, their dissolution supplies us with a number of ready-made experiments in which the influence of each particular factor in the sum total may be detected by watching the changes that ensue on its removal. In a word, the method of evolution is the atomistic method, extended from matter to motion, and viewed under the form of succession instead of under the form of co-existence.
