TWO:The man looked and nodded. He winked at his companion, and together they strode out of the house. With a silent laugh Maitrank crept up the stairs.

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:"At six o'clock a captain separated the men from the women and children. The women were placed behind a line of infantry. The men had to stand alongside a wall; those in the first row were ordered to sit on their haunches, the others to remain standing behind them. A platoon took a stand straight opposite the group. The women prayed in vain for mercy for their husbands, their sons, and their brothers; the officer gave the order to fire. He had not made the slightest investigation, pronounced no sentence of any sort.
  • 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:A short time after the destruction I was even obliged to accept it for a whole week, as on the same day on which I arrived in Louvain for another visit there was renewed fighting round the town. The Belgians had advanced as far as Rotselair, where the next day they held their ground against overwhelmingly superior numbers; but at last they had to retire, leaving a great many dead behind. The Belgians had even got on to the road Tirlemont-Louvain, and blown up the railway line in two places.

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

THREE:"Numbers?" Prout snapped. "Which part of them?"
  • 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:By examining automatic hammers it will be found that their valves are connected to the drop by means of links, producing [162] coincident movement of the piston and valve, and that the movement of one is contingent upon and governed by the other. It will also be found that these connections or links are capable of extension, so as to alter the relative position of the piston and valve, thereby regulating the range of the blow, but that the movement of the two is reciprocal or in unison. Reasoning inductively, not discovering or inventing, it may be determined that to secure a stamp blow of a hammer-head, the valve must not open or admit steam beneath the piston until a blow is completed and the hammer has stopped.

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
