TWO:Lucy promised to be circumspect, and in less than ten minutes placed a flagon of her father's best ale before the galleyman, and then bounding away with a light laugh, as Wells sprang forward to pay for it with a kiss, her little form was instantly lost in the darkness of the evening.

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 15
  • 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:She stole out of the kitchen into the peace of the dark house, ran up the stairs, and found the right door in the unlighted passage. The bedroom was very big and cold, and on the threshold she wrinkled up her nose at a strange scent, something like hay and dry flowers.Chapter 6

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

THREE:"What'll Handshut think it?"Naomi's money had been the greatest possible help. He had roofed the Dutch barn, and retarred the oasts, he had bought a fine new plough horse and a waggon, and he was going to buy another piece of Boarzellten or twelve acres this time, of the more fruitful clay-soil by the Glotten brook. Naomi was pleased to see all the new things. The barn looked so spick-and-span with its scarlet tiles, and the oasts shone like polished ebony, she loved to stroke the horse's brown, snuffling nose, and "Oh, what a lovely blue!" she said when she saw the waggon.
  • 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:He had struck the path that ran by the bottom of the garden, and swaggered along it with the seaman's peculiar rolling gait, accentuated by strong liquor. Caro felt him coming nearer, and told herself uneasily that she had better go back into the house. He was drunk, and he might speak to her. Still she did not move, she found herself clinging to the gate, leaning her breast against it, while her tongue felt thick and dry in her mouth.

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