BAT is to reduce the sulphur content of the coke oven gas (COG) by using one of the following techniques:
- I..
desulphurisation by absorption systems
- II..
wet oxidative desulphurisation.
The residual hydrogen sulphide (H2S) concentrations associated with BAT, determined as daily mean averages, are < 300 – 1 000 mg/Nm3 in the case of using BAT I (the higher values being associated with higher ambient temperature and the lower values being associated with lower ambient temperature) and < 10 mg/Nm3 in the case of using BAT II.
