Improving the performance of dry-quenching units by minimizing coke losses

Resumo

In assessing the operational efficiency of dry-quenching units at coke plants, it is important to consider the coke losses. In the present work, existing methods of determining the coke losses are analyzed. The method selected is based on continuous measurement of the flow rate and composition of the excess circulating gas released from the dry-quenching unit; it is compatible with different coke-discharge systems. Methods of determining the productivity of the dry-quenching unit are assessed. Means of reducing the coke losses are discussed.
