TWO:"Because," was the reply, "they want to keep the cable straight while they are braiding it. As fast as they braid it it hangs down by its own weight, and coils on the ground beneath. No expensive machinery is needed, and the principal labor in the business is to carry the bamboo fibre to the platform where it is wanted. This cable is very strong and cheap, and takes the place of hemp rope in a great many ways. It is larger and rougher than a hempen rope of the same strength, but the Chinese are willing to sacrifice beauty for cheapness in the majority of practical things.""We are now at the Great Wall, which comes straggling over the hills that surround the city, and forms its northern boundary. It is very much in ruins, but at the town itself there is a portion of it kept in good repair, and one of the gates is regularly shut at night and opened in the morning. Some of the old towers are still in their places; but the weather is slowly wearing them away, and in time they will all be fallen.

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:It isnt only his attendance there that I mean,{104} said Mr Silverdale. But you know his Stores are in my parish, and he employs some four hundred work-people there. I went to see him at his office this morning, and asked him if I couldnt have a daily service for them.
  • 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:KIOTO AND LAKE BIWA.

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

THREE:
  • 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:"Wish what?"

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
