Co-incineration as fuel source (cement works, lime kiln, power plant...)
Co-incineration as fuel source (cement works, lime kiln, power plant...)
Type of treatment: Treatment
Description:Incineration of the liquid oil recovered as fuel source in cement works (and/ or industrial furnaces)
Note. Co-incineration is the incineration of waste in industrial incinerators, kilns, furnaces as an alternative or complementary fuel source and/ or as material source.
Waste:
Liquid
Pasty waste
Depending on installation: solid waste
Situation/Possibilities in the country:
Some cement facilities have special adaptations to receive OSW as fuel.
Interest:
Entry criteria:
Pre treatment is often needed.
Operational constraints:
Impacts:
Incinerators may release carcinogenic and toxic chemicals, including heavy metals, partially-burned organic material such as polyvinyl chloride (PVC), and other organic chemicals, including polycyclic aromatic hydrocarbons (PAHs), dioxins and furans.
The concentration of the release depends on the type of waste, of incinerator and of filter installed on the chimney.
See the Appendix “Emission limits for co-incineration in cement kilns”, p.107
Legal constraints:
Refer to incineration and atmospheric releases legislation.
Special authorisation may be required for such work.
Efficiency:
Depends on the substitution rate : from 1 to 1.5 tons/ day
Cost:
CAPEX: use of already existing installation, may require adaptation to handle oil spill waste.
OPEX: Estimated to 30 to 50 Euros/ ton (may be 0 euro if oil does not need pre-treatment), depending on the quality of the recovered oil and on the additional cost for waste pre-processing in the plant (demulsifying, screening for absence of heterogeneous elements etc.).
