The increasing focus on sustainability of Steel Industries worldwide has brought in new trends, viz. maximizing utilization of assets and reduction of energy consumption and carbon footprint. Coke dry quenching (CDQ) technology for recovery of waste heat from hot coke to generate process steam and power is well established and adopted worldwide that meets these objectives of sustainable operation. Conceptualizing and executing CDQ technology in brown field site conditions throws up many challenges requiring innovative approach for technically and financially feasible solutions. The complexity of the situation is compounded with the requirement of proper technology selection based on space availability, synchronization of CDQ operation with oven pushing schedule, integration of the process with existing system, keeping the existing coke oven batteries operative as well as adhering to maintainability, process safety protocols and constructability of new facilities within the project execution schedule. Brief description of CDQ process, advantages and challenges for implementation of the same in brownfield unit has been described in this paper with examples/ references.
