United States Patent No.: US 10,566,079
Date of Patent: Feb. 18, 2020
Characterization Of Complex Hydrocarbon Mixtures
Disclosed are processes for improving the performance of a computer system operating a software program for calculating operating parameters and results of hydrocarbon processing units by
providing a method of estimating and consolidating molecular composition components and properties of hydrocarbon mixtures such as petroleum fractions. The method provides a reduced number of
representative compounds that closely match the characteristics of the complete molecular composition of the mixture that may be used to increase efficiency of a computer system, improve the
operation of refinery process and that may be disposed on non-transitory machine-readable media.
United States Patent No.: US 11,776,667
Date of Patent: Oct. 3, 2023
COMPOSITION TRACKING OF MIXED SPECIES IN CHEMICAL PROCESSES
Systems and methods of chemical process simulation providing improved methods and systems for expressing the
composition of a stream in a chemical process model in a
manner that is not immediately indicative of the underlying
composition, providing for improved accuracy of allocation
of a process output stream to the appropriate source(s),
avoiding duplication of components or other inaccurate
component representations in relation to critical calculations, and improving the operation of a computer or other
computing system for performing chemical process modeling and simulation. The systems or methods provide for
three distinct layers of interaction, separating mixed species
displayed to the user from individual species used in calculations, while providing transformation objects between
dataset layers to provide for accurate modeling, calculation, and display.
