Air pollution control systems
Most of the air pollution control systems built in the Chinese WTE plants are similar to the predominant gas control systems in the US: a combination of semi-dry scrubber, activated carbon injection (to remove volatile metals and organic compounds) and fabric filter baghouses (to remove particulate matter). In some WTE plants, selective non-catalytic reduction is included to remove nitrogen oxides, such as, for example, the WTE plants under design for Guangzhou, Shantou, and Chongqing.
