Coke is an essential component of the feed to iron blast furnaces. The present technology for its manufacture is based on heating coal in retorts in absence of air then quenching the product with a limited supply of water shower which is highly polluting. In dry quenching process nitrogen is used in a closed circuit to avoid environmental emissions. In addition, heat is recovered in the form of steam, from the red-hot coke. This fits the industry very well because oxygen is used extensively in steelmaking and therefore by-product nitrogen from air liquefaction can be effectively utilized in this way.
