Article Preview

In this paper, a new coke dry quenching (n-CDQ) technology is proposed. The advantages of this technology are energy conservation, pollution reduction, coke quality improvement and the full use of resources. Based on the idea of the n-CDQ technology, process modeling is conducted using the process simulator of Aspen Plus. The impacts of the flow of the coke-cooling coke oven gas and the consumption of the steam on the new CDQ technology are discussed. The results show that the maximum concentration of CO reaches about 16% and the H2 56% when the steam consumption is approximately 0.5 t/t coke and coke oven gas 150-160 Nm3/t coke. The steam produced is more than the consumed, which means that the excess steam can be used for power generation. In this way, the advantages of the n-CDQ technology are fully revealed.
