Abstract

1,137, 983. Electrolytic production of chlorine from molten salt baths. PHILBLACK Ltd. May 19, 1966 [June 1, 1965], No.22291/66. Addition to 1, 011, 818. Heading C7B. Chlorine which will cause no appreciable corrosion to iron or steel is obtained from a molten salt process in which a molten metal chloride salt is electrolyzed in a substantially airtight electrolysis zone maintained at a pressure not exceeding the existing atmospheric pressure and maintained at a temperature sufficient to maintain the salt in a molten state whereby gaseous chlorine is evolved, which gaseous chlorine is withdrawn from the electrolysis zone at the temperature of said zone, co-mingled with a second stream consisting of dry chlorine having a greater linear velocity and at least twice the mass of the evolved chlorine stream and having a sufficiently low temperature that the resultant co-mingled chlorine stream has a temperature of less than 300‹ F. The mass of the second chlorine stream is preferably at least five times that of the evolved chlorine, and the pressure in the electrolysis zone may be maintained so as not to exceed the existing atmospheric pressure by regulation of the mass and velocity of said second chlorine stream. Apparatus described is as in the parent Specification.
