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:The Captain interrogated him as to who he was and what he was doing out there, while the scout fidgeted in his saddle over the time that was being wasted."There's likely to be from 100 to 150 in there," said the Lieutenant, after a moment's consideration. "We've got 27 or 28. We'll jump them, though, if they're a thousand. Corporal Elliott, you go forward and make your way inside, if you can, and see what they are doing. If you can get inside, stay 10 or 15 minutes, and come out and report. If you can't get out, or you think they are ripe for jumping, whistle, and we'll pile in. Sergeant Klegg, you hold your squad together and move down as near the door as you can without being seen and be ready for a rush. Find a rail or a log to smash the door in if they try to hold it against us. Sergeant Ramsey, deploy your men quietly around to the rear there to cut off retreat, but be ready to rally again and help Sergeant Klegg out if he strikes a big snag. You make the circuit of the house and post yourself where you can see what's going on, and signal your men. Everybody keep under the shadow of the trees and make no noise. Go on to the house, Corporal."
  • 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:Cadnan felt a surge of hope. Marvor might leave, take away the disturbance he always carried with him. "You will go and join them?""I tell you. Shorty, there's a gun in there that'd just tickle your boy to death. It's an Enfield, new one, and has a Yankee bullet sticking in the butt. Must've knocked the Johnny a double somersault when it struck. I've been thinkin' sending it home myself. But I'll let you have it, and I'll tell you how you can get it. See that camp over there? Well, that's a regiment being organized out o' Tennessee refugees. They and their officers are the carelessest lot of galoots that ever lived. Their Quartermaster stores and their Commissary stores, and everything they have is allowed to lie around loose, just wherever they get the notion to drop them. I've had my eye on 'em for several days, and've helped several of my friends to straighten up their company accounts, and replace things that they'd lost. You just waltz over there, careless like, as if you belonged to the regiment, pick up a gun and traps, put 'em on, and sail back here, and I'll turn your things in, and give you that gun with the bullet in the stock in exchange."

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

THREE:"Well, SO far's you're concerned and to all general purposes he is. You needn't pay no partickler attention as a rule to nobody else, but when the Orderly speaks, you jump, and the quicker you jump the better it'll be for you. He don't draw as much salary, nor put on as many frills as the bigger fellers, but you hain't nothin' to do with that. You kin find fault with the Captain, criticize the Kurnel, and lampoon the General, but you don't want to give the Orderly no slack. He's not to be fooled with. Russell, run up there and snatch that spade to dig ditches around these tents."
  • 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:"Word came to Headquarters," explained the Lieutenant, "that a squad of recruits were rioting, and had killed a citizen, and I was sent down here on the run to stop it and arrest the men. This Sergeant, who seems to be in command, refuses to go with me."Another swift push of two or three miles brought them toward the foot of Mission Ridge, and near the little, unpainted frame house which had once been the home of John Ross, the chief of the Cherokees.
