Flue gas treatment with powder activated carbon
The incineration of waste such as Municipal Solid Waste (MSW), hazardous industrial waste, medical waste and sewerage sludge results in the formation of a flue gas containing a range of pollutants. Most of these pollutants can be removed by conventional treatment methods such as scrubbing, bag filters and Electrostatic Precipitators (ESP). However, dioxins and heavy metals such as mercury and cadmium are not normally removed to low enough concentrations by conventional treatment. The dosing of Powder Activated Carbon is an effective technology to remove these substances to the low limits required by legislation.
Chemviron Carbon has two standard products, PULSORB® FG4 and FG5.
PULSORB® are a range of steam activated powder activated carbons from coal and coconut precursors used for the removal of dioxins and mercury in the following types of incineration facilities:
- Municipal Solid Waste
- Industrial and hazardous waste
- Medical waste
- Sewerage sludge
PULSORB® can also be used for the treatment of gases in metal process industries. Both products are available in big bags, sacks or in bulk.
PULSORB® carbons have several properties, which explain their superior performance in most types of flue gas treatment systems:
- The most simple and effective method to meet stringent regulations of 0.1ng/Nm³ TEQ for dioxins and 0.05mg/Nm³ for mercury.
- High adsorption capacity for dioxins and mercury, giving lower carbon consumption with reduced operating cost.
- Low capital cost. Can be incorporated into an existing flue gas treatment system very quickly
- Optimal mesh size that ensures a rapid rate of adsorption.
