Halogenated compounds (specific catalysts required)
(Fine organic particles)
The yield for heat recuperation can be as high as 98 %, as in regeneration with non-catalytic afterburning. In recuperative catalytic afterburing, autothermic combustion is possible from 1 -2 g/m³ of solvent . According to BAT [7,9] autothermicity is realised from 0.5 -1.5 g/m³.
In the interest of safety, the hydrocarbon concentration in the flue gas mix must be kept below 25% of the lowest
explosion limit (LEL).
Dust concentrations less than 3 mg/m³ .
Only extra fuel needed. The amount required is much lower than a set-up with afterburning.
See technique sheet 35
Determined by gas composition. Low energy use compared to situation without heat recuperation. Autothermicity is realised from 0.5 -1.5 g/m³ [7,9].
- Operating costs
Personnel costs: 2 days per year 
Operating costs: 3 600 to 12 000 USD per year for 1 000 Nm³/h 
Total cost aspects per ton of solvent amounts to 150 – 26 000 USD/ton per year 
Major cost factors
Flow rate: Size of installation
Energy content of gases: Higher energy content means less extra fuel
Required removal efficiency determines the residence time. Higher efficiency means higher costs
Type of catalyst
Measurement and configuration equipment
Case study: Glue spraying booths 
Flow rate: 10 000 m³/h
Load: 1 270 mg C/Nm³
16 hours per day operation
Investment costs: 307 000 EUR excl. VAT
Case study: flexographic printing :
Flow rate: 13 000 m³/h
Investment costs: 340 000 EUR excl. VAT
Advantages and disadvantages
See catalytic oxidation
No corrosion problems with heat exchanger
Homogenisation of gas stream in the bed
Extensive energy recuperation:
Relatively low operating costs
See catalytic oxidation
High investment costs
Ceramic beds may become blocked
In discontinuous operation, the bed must be re-heated every time
Large size and weight
A lot of maintenance and moving parts
In most cases, a thermal regenerative system is installed instead of a catalytic system because thermal yield is very high. A catalytic system is relatively expensive.
Applications are more-or-less the same as thermal regenerative afterburning , on the condition that no catalyst poisons are present.
