TWO:"Great God!" cried Holgrave, rushing forward to look at the infant,the feelings of the father overcoming every selfish consideration.

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:
  • 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:Reuben, though he would not have confessed it, was much taken with his son's appearance. Richard looked taller, which was probably because he held himself better, more proudly erect; his face seemed also subtly changed; he had almost a legal profile, due partly no doubt to a gold-rimmed pince-nez. He looked astonishingly clean-shaven, he wore good clothes, and his hands were slim and white, not a trace of uncongenial work remaining. He had quite lost his Sussex accent, and Reuben vaguely felt that he was a credit to him.Meantime affairs at Grandturzel were going from bad to worse. Reuben did not speak much about Grandturzel, but he watched it all the same, and as time wore on a look of quiet satisfaction would overspread his face when it was mentioned at the Cocks. He watched the tiles drip gradually off its barn roofs, he watched the thatch of its haggards peel and moult, he watched the oasts lose their black coats of tar, while the wind battered off their caps, and the skeleton poles stuck up forlornly from their turrets. Holes wore in the neat house-front, windows were broken and not mended, torn curtains waved signals of distress. It was only a question of waiting.

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

THREE:Immediately upon De Boteler's departure, which occurred in a few days, measures were taken to procure a royal grant of the villein to his late lord; and upon the instant of its being obtained, Calverley, attended by about a score of retainers, left the castle, without the slightest apprehension for his personal safety, or the most distant fear that his application would fail.Chapter 20
  • 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:For some obscure reason Caro did not like to see [Pg 284]herself credited with the harshness of inexperience. She did her best to assume an air of worldly toleration."I tell you, steward," said the smith who had before spoken, and stepping so near Calverley that he involuntarily drew back, "if you prize your life, you will call no man here a bondman. I am freethat man is free" pointing to Holgrave, "and we are all freeall sworn brothers; and no one shall dare," raising his voice, "to brand, with such a name, a mother's son among us! You have received fair warning, and leave to go: retire nowinstantly, if you are wise! Clear a passage there for my Lord de Boteler's steward! There is now room for you to passyour retainers are waiting withoutand now take the man you call a bondman, and away with you all. What! you will not lay hold of him? Take him, I say!" elevating his voice"seize the villein, and drag him back to his bondage! What! not a finger, after all the trouble you have taken?then, away with you alone!away!" And Calverley, from the mere instinct of obedience to a superior power, moved towards the door. "And if ever," continued the smith, "you are found hunting in this forest again for bondmen, as you call them, we may chance to give you a lodging where you will have little reason to complain that the sun shines too brightly!"
