The raw gas composition from primary aluminium production depends mostly on the process technology applied and the composition of the raw materials. At steady state, a stationary condition is established among the material sources, gas production and sinks: the gas treatment centre and escaping gases. Only a few papers …
Aluminum smelters worldwide are challenged by increasing ecological and economical pressure. Higher line amperages gain production output but increase the HF load on dry scrubbers. Another important factor today is the tight alumina market, hence it …
The main air pollution control systems in primary aluminium smelters are focused on control of particulates and fluorides. Generally, only some smelters apply additional control systems to abate the emissions of sulfur, primarily in the form of sulfur dioxide (SO 2).This is driven by specific conditions, like in Norway, or by cumulative …
Aluminum smelters worldwide are challenged by increasing ecological and economical pressure. Higher line amperages gain production output but increase the HF load on dry scrubbers. Another important factor today is the tight alumina market, hence it is necessary to accommodate dry scrubber and potline operations to different alumina …

NOx Scrubber . Valmet NOx Scrubber is the best solution when low NOx emissions are required, process conditions are challenging for conventional methods such as SNCR or SCR. The scrubber suits well for recovery boilers, lime kilns, incinerators, waste-to-energy plants, refineries and other industrial applications. A true multi-emission control ...
Wet scrubbers use liquid to capture pollutants via absorption or chemical reaction, while dry scrubbers employ dry sorbent materials like lime or activated carbon for adsorption. These systems are vital for mitigating airpollution by removing harmful emissions from industrial processes before release into the environment.
Therefore, these types of scrubbers find use in most types of plants, including energy production, manufacturing and waste treatment facilities. Other Types of Industrial Scrubbers While wet and dry scrubbers are the two most commonly used types of industrial scrubbers, electrostatic precipitators are another option.
