Waste-to-Energy and Syngas
Air Pollution Control in the Waste-to-Energy Industry
Waste-to-energy (WtE) or Energy-from-Waste (EfW) is the process that generates electricity and/or heat from the combustion or the gasification of waste, RDF (Residual Derived Fuel), MSW (Municipal Solid Waste) or biomass. It can also produce a combustible fuel such as methane, methanol, ethanol or synthetic gas (Syngas).
Fives designs state-of-the-art air pollution control and gas cleaning technologies to meet the very stringent requirements of the Waste-to-energy.
Fives’ air pollution control systems comply with most of the feedstock types: coal, waste, biomass, petcoke or fuel oil. They can also suit to hazardous and medical waste incineration and treatment applications.
The new Dry Scrubbers AD-NOx™ and EAD-NOx™ for NOx control have been developed to avoid the use of an additional SCR or SNCR in the waste-to-energy processes. DeNOx is achieved directly within the baghouse.
Fives can reduce or remove most of the pollutants often released from Energy from Waste and Syngas processes:
- Particulates (PM10, PM2.5), ash, tar, SO2, SO3, HCl, HF, NOx, mercury, dioxins/furans, heavy metals, VOCs
- HCN, H2S, COS and NH3 (syngas additional pollutants)
- Flue Gas Desulfurization and Scrubbing
- NOx control on combustion turbine, boiler or engine Flue Gas
- Tars removal from Syngas on gasifier
- Syngas cleaning on gasifier for further downstream use
- High temperature Scrubbing on thermal processes
