Predictions Using Literature Values of Parameters

The correlations given by Equations 12.7 through 12.24 were used to predict hydrotreating product properties such as API gravity, CCR, RCR, asphaltenes, metals, and sulfur contents. They have as independent variables some product properties as well as some operating conditions. Most of the equations are relatively simple

Parity plots of experimental versus calculated product properties were also obtained. It was found that other five correlations (Equations 12.38, 12.51, 12.58, 12.84, and 12.104), of different types adequately reproduce the results of some feedstocks.
