Home / Industries / Chlor-Alkali / Sodium Chlorate Production Sodium Chlorate ProductionThe production of
sodium chlorate for the pulp and paper industry's chlorine dioxide generation
systems has grown dramatically since the EPA Cluster Rule forced modification
of the bleach plant bleach sequence to favor chlorine dioxide instead
of chlorine and hypochlorite.
Sodium chlorate plants feature an electrolytic cell line and reactor chambers to allow the slow reaction to form NaClO3 to occur. Crystalizers are employed to form solid crystal chlorate. Shipment to the customer is typically made in crystal form or by redissolving the crystal to form specialized concentrations for use in a particular chlorine dioxide facility. The bleaching of pulp accounts for the vast majority of consumption of sodium chlorate made. Andritz Automation's personnel have managed both monopolar and bipolar sodium chlorate plants and fully understand this process. Of the many projects and upgrades done in chlorate plants, our particular emphasis has been in managing the largest production cost in the manufacture of chlorate, the cost of electricity. Because of Andritz Automation's extensive background in High Voltage Systems and DC rectification, we have been able to upgrade and solve operating problems for several chlorate manufacturers while preserving the strict confidentiality inherent in this industry. Serving the needs of sodium chlorate facilities remains a core business for Andritz Automation.  |
