    摘要： A method for supplying a chlorine gas to a reactor (7) which comprises the steps of cooling the chlorine gas to convert it into liquefied chlorine, transferring the liquefied chlorine to a location near the reactor by pressure and heating the liquefied chlorine to convert it into a chlorine gas, and supplying the chlorine gas to the reactor (7). Using this method, a chlorine gas can be stably supplied to a reactor (7) under a small load and the amount of impurities contained in the chlorine gas and undesired for a chlorination reactor (7) can be reduced in this process.

    摘要： This invention provides a method for purifying a chlorine supply that includes a chlorine component, a bromine component, and nitrogen trichloride. The method includes the steps of introducing the chlorine supply into a vaporizer, heating the chlorine supply in the vaporizer to form a vapor, and introducing the vapor into a distillation system to provide purified chlorine gas, a distillate that includes liquid chlorine and the bromine component, and a bottoms component including the nitrogen trichloride. The method also includes the steps of condensing the vapor in a reflux condenser, heating the condensate in a reboiler, removing the purified chlorine gas from the distillation system, and removing the distillate from the distillation system.

    摘要： It is intended to provide methods of producing a chlorine gas having a small bromine content, an aqueous sodium hypochlorite solution having a small bromic acid content, and liquid chlorine having a small bromine content. More specifically, a chlorine gas is produced by a method comprising the steps of: (A) washing a chlorine gas that contains bromine, in a gas washing unit composed of a packed column or a tray tower, wherein the chlorine gas introduced via a lower part of the gas washing unit is brought into counterflow gas/liquid contact with a liquid chlorine introduced via an upper part of the gas washing unit; and (B) taking out a purified chlorine gas thus washed, via the upper part of the gas washing unit, wherein a weight ratio of the chlorine gas and the liquid chlorine introduced in the step (A) is 1/1.0 to 1/0.3.

    摘要： A crystallization separation process for separating an at least partially liquid mixture containing two volatile components (A and B) the two components forming a binary system in which the vapor pressure ratio of A:B is 0.1 to 10 at the B-triple point and is less than the ratio of the heat of sublimation to the heat of melting of the B-component at the B-triple point, the constant pressure phase diagram having a B-enriched solid-vapor two phase region covering a substantial concentration range above the three phase state temperature and a B-enriched solid and liquid region below such temperature wherein a first vapor mixture and first condensed mass are formed by vaporizing the two components in a first zone at a temperature and pressure lower than the triple point temperature and pressure, the first condensed mass comprising a mother liquor and a solid phase which is B-enriched, the heat released in the formation of the solid being utilized to vaporize the volatile components.
    Such process can be extended to a gas mixture containing two volatile and condensable components (A and B) into substantially pure B and a B-lean component, in which heat is removed from the gas to cause part of the B to desublime, the A remaining in the vapor stream, the vapor stream then having heat removed therefrom while the vapor is at a temperature and pressure below the B-triple point values thereby causing formation of a further condensed mass.
