Introduction and Background: Catalytic Off-Gas Treatment in Metallurgical Processes
Catalytic conversion of carbon monoxide (CO) and volatile organic compounds (VOCs) in metallurgical off-gases presents several challenges. These include the presence of catalyst poisons (e.g., arsenic, lead, hydrogen fluoride), high dust loads, and fluctuating inlet temperatures.
One specific challenge—the variable and often undefined concentrations of sulfur dioxide (SO₂) in the gas stream— is mitigated by increasing the inlet temperature. The non specified and changing concentrations of SO2 in the gas stream is tackled by the increase of the inlet temperature to the catalyst, which is positioned on top of a hot gas filter system keep the temperature loss and dust load minimal (see Fig. 1).
The Catalytic Performance
a) The Inlet Temperature
As a rule of thumb Arrhenius´ law states that reaction rates shall double every 10 °C of temperature-increase. This chemical law is employed to enhance the catalytic activity of overall system.
b) The Catalyst Volume
The calculation of the catalyst volume plays an essential role by the efficient oxidation. Furthermore, regularly renewal of catalysts is advised. Older catalyst can stay and serve as a first-contact, sacrificial layer to absorb poisons and prolong the activity of fresh material.
All Non-Ferrous Metallurgy Companies can benefit from this process reducing their emissions and cutting the CAPEX and OPEX!
This process demonstrates the feasibility of catalytic off-gas treatment for CO and TVOC oxidation in non-ferrous metallurgical processes.
The second way to increase the reliability of the catalytic turnover is to oversize the catalyst volume to tackle possible poisoning or aging of the catalyst.
P&Ps catalyst experts can recommend a service interval for catalytic layers based on the actual process gas composition and plant operation.
