Claims
- 1. A process for producing at least one of chlorite, chlorine dioxide and chlorate comprising:(a) feeding ozone and oxygen into a water stream containing chloride to produce ozonated-chloride water; and (b) electrolyzing said ozonated-chloride water inside an electrolytic cell to produce at least one of chlorite, chlorine dioxide and chlorate wherein the feeding step takes place in a contact chamber having a central vertical axis and defining an enclosed space and having an inlet, an outlet, a top and a bottom, wherein said ozonated-chloride water enters at the top of said enclosed space and is withdrawn within 2 inches of said bottom to produce ozonated water, wherein the ozonated-chloride water is injected into said enclosed space through said inlet and tangential to said central axis to impart turbulence and a swirling motion to ozone and water contained within said enclosed space; wherein said ozone generally forms a laminar stratification within said enclosed space, with larger bubbles forming upper strata and progressively finer bubbles forming progressively lower layers; and wherein said ozonated-chloride water with dissolved ozone is withdrawn via said outlet.
- 2. A process according to claim 1, wherein the at least one of chlorite, chlorine dioxide and chlorate are formed in the electrolytic cell by the following reactions:1) Cl−+O3+H+=HOCl+O2 2) HOCl+O3=ClO2−+H++O2+e−3) O3+2ClO2−+2H+=2ClO2+H2O or1) Cl−+O3+H+=HOCl+O2 2) HOCl+O3=ClO2−+H++O2+e−3) O3+3ClO2−+2H+=3ClO3+O2+H2O.
- 3. A process according to claim 2, wherein the at least one of chlorite, chorine dioxide and chlorate are introduced into a water reservoir.
- 4. A process of producing at least one of chlorite, chlorine dioxide and chlorate, the process is carried out in an electrolytic cell by reacting ozone and a chloride water as follows:Cl−+H2O=HOCl+H+2e−(anode reaction in electrolysie cell) Cl−+O3+H+=HOCl+O2 HOCl+O3=ClO2−+H++O2 O3+2ClO2−+2H+=2ClO2+O2+H2O or1) Cl−+O3+H+=HOCl+O2 2) HOCl+O3=ClO2−+H++O2+e−3) O3+3ClO2−+2H+=3ClO3+O2+H2O wherein the ozone and the chloride water are mixed in a contact chamber having a central vertical axis and defining an enclosed space and having an inlet, an outlet, a top and a bottom, wherein ozonated-chloride water enters at the top of said enclosed space and is withdrawn within 2 inches of said bottom to produce ozonated water, wherein said ozonated-chloride water mixture is injected into said enclosed space through said inlet and tangential to said central axis to impart turbulence and a swirling motion to ozone and water contained within said enclosed space; wherein said ozone generally forms a laminar stratification within said enclosed space, with larger bubbles forming upper strata and progressively finer bubbles forming progressively lower layers; and wherein said ozonated-chloride water with dissolved ozone is withdrawn via said outlet.
- 5. A process of producing at least one of chlorite, chlorine dioxide and chlorate comprising reacting ozone and chloride water in an electrolytic cellwherein the ozone and the chloride water are mixed in a contact chamber having a central vertical axis and defining an enclosed space and having an inlet, an outlet, a top and a bottom, wherein ozonated-chloride water enters at the top of said enclosed space and is withdrawn within 2 inches of said bottom to produce ozonated water, wherein the ozonated-chloride mixture is injected into said enclosed space through said inlet and tangential to said central axis to impart turbulence and a swirling motico to ozone and water contained within said enclosed space; wherein said ozone generally forms a laminar stratification within said enclosed space, with larger bubbles forming upper strata and progressively finer bubbles forming progressively lower layers; and wherein said ozonated-chloride water with dissolved ozone is withdrawn via said outlet.
