What is a good pressure setting for the vacuum dechlorination tower? Sodium sulfite consumption is high; what is the typical level of sodium sulfite consumption among you all?
The pressure in the dechlorination tower is generally maintained between 0.2 and 0.4 MPa, but this depends on the process design and actual conditions. The pressure in a vacuum dechlorination tower is generally lower than that in a atmospheric-pressure dechlorination tower, usually maintained between 0.05 and 0.1 MPa. As for the consumption of sodium sulfite, it is affected by various factors such as raw material composition, reaction conditions, and catalyst dosage. Generally, sodium sulfite consumption can be reduced by optimizing reaction conditions and controlling the amount of catalyst used. Different production lines and processes may vary, and the specific consumption levels need to be assessed based on the actual circumstances. .
The pressure in the vacuum dechlorination tower is maintained at a negative pressure level, which generally depends on the specific process requirements and the design parameters of the equipment. The commonly used operating pressure is -0.05 to -0.08 MPa; this range ensures the proper operation of the dechlorination tower, allowing it to effectively remove harmful gases such as hydrogen chloride and chlorine dioxide from exhaust gases. Sodium sulfite is a commonly used reducing agent in vacuum dechlorination towers, capable of reducing hydrogen chloride and chlorine dioxide into harmless salts and water. The consumption of sodium sulfite is related to factors such as the levels of hydrogen chloride and chlorine dioxide, the volume of air inlet, and the operating parameters of the equipment; generally speaking, it is difficult to specify a precise range for the consumption of sodium sulfite. However, in order to control the consumption of sodium sulfite, it is possible to reduce its consumption by controlling the operating parameters of the vacuum dechlorination tower. For example, methods such as using more efficient tray packing, adjusting the inlet gas flow rate, and adjusting the amount of reductant added can all effectively reduce the consumption of sodium sulfite.

The pressure in the vacuum dechlorination tower is generally controlled between -72 and 68 JPa. As for the consumption of sodium sulfite, it is affected by various factors such as the amount of acid added, temperature, the efficiency of spraying in the dechlorination tower, and the flow rate of the dechlorinated brine. With proper control, the consumption of alkali per ton is around 2 KG; some competitors may achieve even lower values
