Linear methods to predict TOX (toxic emissions), NOx (nitrogen oxides), and VOCs (volatile organic compounds) of a blend can help refiners calculate the likelihood that their blend recipes will meet requirements of Phases I and II complex models for reformulated gasoline (RFG).
Multiple regression techniques to predict TOX, NOx, and VOCs are based on the following variables:
Oxygenates content, wt % oxygen
Reid vapor pressure (Rvp), psi
Sulfur content, ppm
Aromatics content, vol %
Olefins content, vol %
E200, % fuel evaporated at 200° F...
