Division 51

BAT for coke quenching is to reduce dust emissions by using one of the following techniques:

1. I..

   using coke dry quenching (CDQ) with the recovery of sensible heat and the removal of dust from charging, handling and screening operations by means of a bag filter

2. II..

   using emission-minimised conventional wet quenching

3. III..

   using coke stabilisation quenching (CSQ).

The BAT-associated emission levels for dust, determined as the average over the sampling period, are:

• < 20 mg/Nm³ in case of coke dry quenching

• < 25 g/t coke in case of emission minimised conventional wet quenching^f1

• < 10 g/t coke in case of coke stabilisation quenching^f2.
