WHAT'S COKE DRY QUENCHING (CDQ)? "The red-hot coke is cooled by inert gases, instead of conventional water quenching. It not only effectively utilises the thermal energy of red-hot coke (80% of the sensible heat of coke can be recovered and made use of for production of steam) but also results in improvement of the coke quality"
