Correlations of Maples

Maples (1993) derived similar correlations based on conunercial and pilot plants at typical operating conditions. The database corresponds to straight-run residues with API gravity and CCR content ranging from 1.4 and 2.5 and 2.84 and 25.5 wt%, respectively. Linear plots to determine product yields in weight percent were reported, from which the following correlations were obtained. A correlation for naphtha yield can be developed from the plot however, Maples (1993) suggested its calculation by difference  

Similar plots than those for product yields were reported for sulfur distribution and API gravity of the products, from which the following lineal correlations were derived  

Maples (1993) also reported another set of correlations for flexi-coking
