Latest Patents

Rizzo holds a patent for a "Method for predicting haze in lubricant base stocks." This invention provides a technique for predicting future haze formation in dewaxed, petroleum-derived lubricant base stocks. The method measures changes in light scattering caused by the formation and disappearance of wax crystals in a dilute test sample of neat base stock over a temperature profile. The data obtained is compared to a historical correlation of measurements taken using light scattering data to assess haze potential. This technique focuses on haze disappearance temperature as a reference point and utilizes a solvent to accelerate wax crystal formation. It offers a robust early warning system for refineries, allowing them to determine the long-term haze potential of base stock production prior to release. The process can be performed in real time, typically in less than an hour.
