Predicting the Quality of OAO Altai-Koks Coke by Laboratory and Box Coking 1. Laboratory Coking

Abstract

Laboratory coking of experimental batch simulating the industrial batch at OAO Altai-Koks provides the basis for a model predicting the quality (CSR, CRI) of laboratory coke on the basis of the coking indices $$C{{I}^{{{{V}_{{\text{o}}}}}}}$$ and CI. The relation derived between the quality (CSR, CRI) of the laboratory coke and the quality (CSR, CRI) of industrial coke produced by wet and dry quenching permits prediction of CSR,CRI for the industrial coke on the basis of predicted or experimental CSR and CRI values for the laboratory coke. This approach permits ongoing determination of the CSR and CRI values of industrial coke produced with wet and dry quenching in the following circumstances: (i) in correcting production batch on the basis of the coal components available in the store and other nearby coal resources; (ii) in correcting production batch by means of outside concentrates not currently available at the plant; (iii)in analysis of the reasons for quality changes of the coke at any moment; (iv) in developing promising batches as the market for coking coal changes.
