CO2 temperature at the outlet of the regeneration tower
Thread Content
Controlling the CO2 temperature at the outlet of the decarbonization regeneration tower at a low level results in less water being carried away, which is unfavorable for maintaining water balance; on the other hand, if the CO2 temperature is too high, its acidity increases, leading to corrosion of pipeline equipment. Please discuss how to properly control the CO2 temperature at the outlet of the regeneration tower
The water balance should not be adjusted by changing the temperature of the CO2 product; even if too much water is removed, it can be adjusted through recycling
I agree with the opinion from the second floor; efforts should be made to reduce the outlet temperature of CO2 in order to minimize equipment corrosion. The horizontal balance of the system can be achieved through gas-based measures.
Reply to 1# Jiangjiang: The one we use for decarburization in our factory works very well. It’s very convenient to adjust the temperature
For the precise control of the CO2 temperature at the outlet of the regeneration tower, our company uses the Kellogg process, and there are no specific means for adjustment; generally, only the regeneration temperature of the regeneration tower is controlled. The regeneration temperature is high, so the CO2 temperature at the tower top is high; if the regeneration temperature is low, then the CO2 temperature is low ； Furthermore, it involves adjusting the amount of water used for washing at the top of the regeneration tower, thereby reducing the CO2 temperature through this water flow. But this wash water is generally rarely used to adjust the temperature. Furthermore, the water balance of the decarbonization system is primarily controlled by the amount of condensate sent out; the quantity of water sent out is adjusted according to the volume of water in the system.
