Abstract: Combined strengthening and corrosion protection of a ferrous metal pipeline is obtained by means of a wrap of ferrous metal strip, the strip being coated with a less noble metal, such as zinc or aluminum or a zinc alloy or an aluminum alloy, and the strip being under sufficient tension to strengthen and reinforce the pipe or to arrest fracture propagation. The less noble metal coating of the strip is electrically connected to the pipe to provide cathodic protection for the pipe. A coating of electrically insulating material may be interposed between the pipe and the wrap. An external power source may be utilized for primary cathodic protection in which case the coated strip is relied upon as a secondary or back-up system.

Abstract: A crude alcohol-containing mixture comprising a saturated aliphatic alcohol of not more than three carbon atoms and associated impurities is processed in a three-tower distillation system to permit recovery of the desired alcohol product in highly concentrated and purified form. In the first tower the crude feed is subjected to extractive distillation with water to remove substantially all the impurities overhead. An aqueous bottoms stream from the first tower containing 5 to 10 wt.% alcohol and only minor amount of impurities is fed to the second tower where the alcohol product is concentrated and recovered. Overhead and intermediate purge streams containing low boiling and hgh boiling impurities are removed from the second tower and are fed to the third tower along with the overhead from the first tower. Stripped aqueous effluent is withdrawn from the bottom of the second tower and is recycled in part to the first tower.
