Railcar Unloading: Sodium Chlorate
Railcar Unloading: Sodium Chlorate - Hydro-Thermal Corp. Flow Rate: Up to 1200 GPM [273 m3/hr] Inlet Temperature: 30°F [-1°C] Discharge Temperature: 190°F [88°C] Steam Supply Pressure: 60 PSIG [4 barg] A major pulp and paper company needed to unload rail cars filled with sodium chlorate using tempered water to dissolve the NaClO3 and create the proper solution strength. They use an elemental chlorine- free process for bleaching in their pulp mills. Traditional ECF replaces elemental chlorine with chlorine dioxide in the bleaching process. 10-20% of product can remain undissolved in railcars and then returned to the chemical manufacturer if the water is not at proper temperature. This company wanted to improve their railcar unloading process by eliminating loss of product due to inc
