Flue Gas Abatement

In order to comply with the stringent legislation such as EU Industrial Emissions Directive 2010/75/EC it is required that all exhaust gases must be processed through a dry gas abatement plant in order to cleanse emissions before they are released to the atmosphere.

This unit, which is built into the final phase section of the incinerator plant, comprises either a specially manufactured bag or a ceramic filter house together with a reagent storage/feed system.

All gases exiting the energy recovery plant are then injected with lime or sodium bicarbonate, together with activated carbon that is held in bulk containers or silos sited adjacent to the gas cleaning system.

As the gas stream passes through the flue gas abatement unit the lime or sodium bicarbonate will create a chemical reaction that effectively neutralizes any acid components such as sulfur dioxide or hydrogen chloride that are present in the gas stream. Simultaneously the activated carbon will adsorb any heavy metals that may be present along with any dioxins.

Following this cleansing stage residual dust from the combustion process along with the spent lime, sodium bicarbonate, and carbon will be captured on the abatement plant filters.

At pre-programmed intervals, this residue is forced from the filters by compressed air into sealed containers that can then be safely transported for controlled and regulated disposal.
