Incineration in industrial incinerator (or other furnace, kiln, power plant...)

Incineration in industrial incinerator (or other furnace, kiln, power plant...)

Type of treatment: Treatment

Description:

Incineration of the waste in specialized incinerators used for hazardous waste / industrial waste.


Waste:

Any type of waste but mainly used for:
Liquids
Semi-solids and solid
Polluted solid waste


Situation/Possibilities in the country:
Installation that may incinerate oil spill waste:
·         Industrial incinerator (850° to 1,100°C)
·         Power plant
·         Lime kiln (operates at 950° to 1050° C)
·         Glass industry
·         Smelting industry

Interest:
·         Permanent waste elimination.
·         Could achieve up to 99% volume reduction.
·         Operated at very high temperature (at 1,200°C), the process is suitable for the destruction of many hazardous air pollutants.
·         Able to handle waste with hazardous substances (Cl, S, heavy metals, PAH, PCB…).

Entry criteria:
Industrial incinerator can accept a wide variety of waste, even heavily oiled (over 30% of oil). Entry criteria depends on the gas and fume treatment capability of the plant.
 
Power plant can accept solid waste (when operating with grill incinerator or fluidized beds). Power plants with fuel burner/ gas burner can accept liquid waste and solid waste (if it is finely shredded).
Other kilns have more restrictive entry criteria, e.g. for lime kiln (France):
·         Size of particle < 10 mm,
·         Calorific power > 2500 kcal/Kg,
·         Water content < 30%,
·         Sulphur < 1%,
·         Total halogens (Cl, Br, F, I) < 1%,
·         PCB < 100 mg/Kg, and PCT < 100 mg/Kg.
 

The oily waste will be added to the incinerated material in a proportion depending on the composition of the oily waste.


Operational constraints:
Requires personnel, site, incinerator and waste handling equipment.
·         No energy is recovered.
·         Air pollution control devices must be suited to monitor the incineration of large quantities of petroleum product.
·         Salt in recovered oil could increase corrosion in system.
·         If the facility does not exist, this type of project needs a long period to be implemented.

Impacts:

Incineration (e.g. in power plants) results in the production of ashes and co-products that must be disposed of correctly.
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.
 


Legal constraints:

Refer to incineration and atmospheric releases legislation.
Special authorisation may be required for such work.


Efficiency:

Relies on the type of incinerator and gas treatment.


Cost:

CAPEX: very high investment cost.
OPEX: 100 to 400 euros / m3 (Source: KOLLER).
