TWO:"I used to know Mrs. Cairness in Washington," Forbes went on, undisturbed; "she has probably told you so."

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:"Where do you want me to go?" he almost moaned, and finished with an oath.

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

THREE:The effect of the American war, so extremely unsatisfactory to the nation, had now perceptibly reduced the influence of Lord North and his Ministry. Their majorities, which had formerly been four to one, had now fallen to less than two to one; and this process was going rapidly on. The changes in the Cabinet had been considerable, but they had not contributed to reinvigorate it. The removal of Thurlow to the House of Lords had left nobody equal to him in the Commons to contend with such men as Fox, Burke, Barr, and the several others. Wedderburn had taken Thurlow's place as Attorney-General, and Wallace had stepped into Wedderburn's as Solicitor-General. Lord Weymouth, who had held the posts of Secretary of State for the North and South Departments since the death of the Earl of Suffolk, now resigned, and Lord Hillsborough was appointed to the Southern Department, and Lord Stormont to the Northern Department. Neither of these changes was popular. The Duke of Bedford's party had become more and more cool towards Lord North, and in every respect there was a declining power in the Cabinet. It was at variance with itself, and was fast losing the confidence of the public. Lord George Germaine was still retained by the king as Secretary of the Colonies, notwithstanding the disgust he had excited by the unfortunate planning of the expedition of Burgoyne.
  • 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:Retreat was now inevitable, and Burgoyne determined to attempt to reach Fort George, at the southern end of Lake George. He had but three days' provisions left, and his force was now reduced to three thousand five hundred men, and these had to make their way through a wilderness swarming with active and elate enemies. Gates, aware of the movement which Burgoyne was intending to make, sent troops up the river to occupy the banks of the Hudson, and to guard all[244] passages of escape. The distance to Saratoga was only six miles, but the rain fell in torrents, the roads were almost impassable, the bridges over the Fishkill were all broken down by the Americans. Burgoyne sent forward detachments of soldiers to repair the bridges and re-open the roads; but they found the woods swarming with riflemen, and that it was impossible to execute the task assigned them. On the 10th, when he arrived at the fords of the Fishkill, he found them obstructed by strong forces of Americans. He soon dispersed them with cannon, but they only retired to the Hudson, where still stronger bodies of troops were posted to oppose his crossing. He might, perhaps, have dispersed these too, but other bodies were seen already in line on the left bank, and to cross there appeared hopeless.The minister nodded his head. "Yes, I reckon there is," he agreed.
