Why are degassing holes installed in the sulfuric acid production process, and what is their function?
If you are referring to the inlet ports of the desorption tower: This helps to improve the efficiency of SO2 desorption from dilute acid and to fine-tune the SO2 concentration in the system, thereby increasing the conversion rate. Openings in the packing tower and purification equipment pipelines: These are used to fine-tune the SO2 concentration in the system and increase the conversion rate. Openings in the pipelines before the drying tower: They are used to adjust the negative pressure of the exhaust gas drawn from the circulation tank, thereby fine-tuning the SO2 concentration in the system and increasing the conversion rate. All of these adjustments are made based on the system’s negative pressure level, and large changes should be avoided to prevent a decrease in production volume
It is mainly used to adjust the SO2 concentration in the furnace gas to ensure optimal conversion efficiency.
