Low gas velocity in the converter
Thread Content
I have a question: if the gas flow rate through the converter is low, less than 0.2 Nm3/s, and domestic catalysts are used, are there any issues with catalyst loading and production, and what are the solutions?
I’ve never seen a converter with such low gas velocity; the catalyst loading must be extremely high. What type of acid production is this?
Low gas velocity leads to uneven airflow distribution, resulting in a decrease in conversion efficiency.
Is the gas velocity 0.2 Nm/s? In domestic designs, it is generally greater than 0.3 Nm/s, while in foreign designs it is usually around 0.4 Nm/s. Solutions: 1. Use a lining inside the converter; 2. Fill it with crushed catalyst.
An inner cylinder can be made at the height where the catalyst is loaded
