Abstract
A method for blending fuel streams to produce a low-sulfur distillate blend includes formulating a blend composition using a model, calculating a projected stability of the determined composition using a predictive stability model, and forming a low-sulfur distillate blend based on the determined composition by mixing determined input streams at the blending ratio. A low-sulfur distillate blend (LSDB) for marine engines includes a blend of residual and distillate fuel streams that satisfies the IMO global sulfur cap of 0.5 wt % sulfur and is stable without any separation of blend components.
