In all cases environmental as well aseconomic issues have been considered and optimized.An interesting enhancement is the alternative utilization of coke oven gas e.g. forthe production of DRI with high potentials for minimizing of investment andproduction costs.In cases, where the demand is predominantly for coke and energy the heatrecovery coking is a reasonable option, especially in connection with compactedcoal charges.REFERENCES/1/ H.B.
