A process for application of alcoholic derivative on heat treated pellets for inhibition of particulate emission is provided, and the process includes weighing the amount of heat treated pellets discharged from furnaces, measuring the temperature of the heat treated pellets discharged from furnaces, applying cooling fluid on the heat treated pellets until they reach temperatures below 140&#xb0; C., and spraying the alcoholic derivative on the heat treated pellets. Also provided is a first device for applying cooling fluid that is capable of calculating a dosage of cooling fluid to be applied to the heat treated pellets, a second device for applying alcoholic derivative that is capable of calculating a dosage of alcoholic derivative to be applied to the heat treated pellets already cooled, and a carrier device that continuously communicates with the first device for applying cooling fluid and with the second device for applying alcoholic derivative.
