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:"Observing the positions of the sun and moon, and of certain stars with relation to each other. That is done with the quadrant and sextant; and then they use a chronometer, or clock, that tells exactly what the time is at Greenwich. Then, you see, this book is full of figures that look like multiplication-tables; and with these figures they 'work out their position;' that is, they find out where they are. Greenwich is near London, and all the tables are calculated from there."MONUMENTS IN MEMORY OF MARTYRS. MONUMENTS IN MEMORY OF MARTYRS.
  • 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:Rose looked cautiously around as though to make sure no one else was in a position to observe her decollet. But the road was empty. It seemed pleasant to see Arthur standing there twirling his walking stick and looking upwards at her. She decided to keep him there for a few moments.

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

THREE:From the place where our friends left their horses to the summit the distance is said to be not far from twenty miles, but it is not exactly the equivalent of twenty miles on a level turnpike or a paved street. Frank said it reminded him of a very muddy road somewhere in California, which a traveller described as nine miles long, ten feet wide, and three feet deep; and he thought a fair description of the way up the mountain would include the height and roughness as well as the length.OVERLAND TO CALIFORNIA.
  • 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:But the wife was absorbed. "Yayse, seh," she was saying to the lieutenant, "and he told us about they comin' in on the freight-kyahs f'om Hazlehurst black with dust and sut and a-smuttyin' him all oveh with they kisses and goin's-on. He tol' me he ain't neveh so enjoyed havin' his face dirty sence he was a boy. He would a-been plumb happy, ef on'y he could a-got his haynds on that clerk o' his'n. And when he tol' us what a gay two-hoss turn-out he'd sekyo'ed for the ladies to travel in, s' I, Majo', that's all right! You jest go on whicheveh way you got to go! Husband and me, we'll ride into Brookhaven and bring 'em out to ow place and jest take ca'e of 'em untel yo' clerk is found."
