Low conversion rate
Thread Content
After the maintenance, the conversion rate remained low; manual removal of a portion of the catalyst was carried out and 10 liters were added. Production of acid from copper smelting flue gas. 31442 process. Two rotations, two suction cycles. 89.94%. 92.71%. 98.17%. 98.37% The exhaust emissions are connected to the online monitoring system of the Environmental Protection Agency. Calcium carbide slag is used for desulfurization. The heat exchanger has no leaks. Imported Topsox catalyst. 414-623 451-556 451-481 416-424 Seeking advice from experts

The cumulative conversion rate for all three tiers of exits is 98%! It might be a problem with the testing or sampling. There is too little data; at least the following information is required: the volume of flue gas processed (or the daily acid production amount)? Local atmospheric pressure, converter inner diameter, and diagram of the converter nozzle positions. It would be ideal to have DCS screens showing purification, conversion, and drying processes; you can send them to my email: 1304699132@qq.com
It is recommended to retest the conversion rate data; the conversion efficiency in the second stage is too low
