High moisture content in coke after quenching presents challenges in blast furnace operations
and product quality. This study explores a novel approach to reducing coke moisture content
during quenching by utilizing a patented water-soluble surfactant. The surfactant addition
aims to decrease the surface tension of the quench water, promoting better wetting and faster
evaporation from the coke surface.

Bokaro Steel Plant has six functional Coke Oven Batteries catering to the coke demand of
Blast Furnace. Hot coke is cooled through wet quenching process. The investigative study
covers Quenching Tower 4 where the coke moisture varies from 5-6 % (wt/wt). The research
investigates the effectiveness of surfactant concentration and its impact on the final coke
moisture level. The study will also assess the influence of this method on other crucial coke
quality parameters such as strength and reactivity.

The objective is to evaluate the potential of surfactant-aided quenching as a viable strategy


for achieving lower coke moisture content without compromising coke quality. This approach
can lead to improved blast furnace performance, reduced coke rate, lower emissions and
potentially enhanced product quality.
