Control of crude refining by a method to predict lubricant base stock's ultimate lubricant preformance |
摘要 |
A model to predict the quality of a lubricant base stock for use in a plurality of products having a plurality of viscosities. The compositional model is based on a quantitative analysis of key compositional parameters and performance criteria for the plurality of products representing the plurality of viscosities. The compositional model provides a method for making a lubricant base stock to be used in manufacturing a lubricant for a particular application from a refinery stream wherein the lubricant base stock and the refinery stream are characterizable according to a plurality of compositional components common to the base stock and to the refinery stream. This method begins with determining the acceptable region and adjusting for viscosity variations. Next, the amounts of the identified compositional components are identified for a lubricant base stock that, in combination, are required for acceptable lubricant performance and the amounts of identified components, in combination, in the refinery stream are determined to be outside of the acceptable range for such identified components. The refinery stream is then refined to produce a lubricant base stock having a combination of identified components within the acceptable range as determined by the model.
