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:On the 21st of October the British fleet sailed from Copenhagen Roads; at Helsingfors the fleet was saluted by the King of Sweden, who invited the admirals to breakfast; and, by the end of the month, was anchored in Yarmouth Roads safely, with all its captives. Fresh offers of alliance with Denmark were made before leaving, accompanied with promises of restoration, but were indignantly refused by the Crown Prince; and no sooner were the British gone, than the Danes converted their trading-vessels into armed ones, and commenced a raid amongst the British merchants, now in the Baltic, for the protection of which some men-of-war ought to have been left. The Crown Prince, now thrown completely into the arms of the French, made a declaration of war against Britain, and the British Government issued an order for reprisals on the ships, colonies, and property of the Danes. They also seized on the island of Heligoland, a mere desolate rock, but, lying at the mouth of the Elbe, and only twenty-five miles from the mouths of the Weser and the Eider, it was of the greatest importance, during the war, as a safe rendezvous for our men-of-war, and as a dep?t for our merchandise, ready to slip into any of the neighbouring rivers, and thus, by smugglers, to be circulated all over the Continent, in spite of Buonaparte's embargo. It served also to remind the people of those regions, that, though Buonaparte ruled paramount on land, there was a power on the sea that yet set him and all his endeavours at defiance.
  • 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.

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

  • 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:The claims of Ireland seeming, for the moment, to be happily satisfied, Ministers now proceeded to carry out those reforms for which they had loudly called during the many years that they had been in opposition. They adopted and introduced the Bills of Sir Philip Clerke and Mr. Carew for excluding contractors from the House of Commons, and revenue officers from voting at elections. The Bill against the contractors passed the Commons with little difficulty; but the Ministers immediately felt the mischief of allowing Lord Thurlow to retain his place of Chancellor. He opposed the measure vehemently, and divided the House upon it. Lord Mansfield gave it his cordial resistance, and the new Lord Ashburton, though created by the present Administration, tacked to it a clause exempting all gentlemen who merely contracted for the produce of their estates. The clause, however, was lopped away again on the return of the Bill to the Commons, and the Act passed without it. The Bill for disqualifying revenue officers was opposed with equal pertinacity by Thurlow and Mansfield; though Lord Rockingham stated that the elections in seventy boroughs depended chiefly on revenue officers, and that nearly twelve thousand of such officers created by the late Ministry had votes in other places. The Bill passed, after exempting all officers who held their posts for life, and therefore were charitably supposed to be beyond the reach of undue influence, as if no such thing as promotion had its effect.
