Abstract: 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.

Abstract: A method of analysis of turbo-machinery that is used in control, monitoring and analysis of turbo-machinery; in improving the operation of a computer system running programs programmed to calculate, inter alia, turbomachinery operation parameters and performance; and which novel approach may be expressed in machine readable language and disposed on non-transitory machine-readable media. The method allows (1) a real-time performance monitoring a computer implemented applications that communicates with Process Simulation (CPS) systems and process plant information (PI) systems describing turbo-machinery equipment performance at design and off-design operating conditions.

Abstract: A process for simulating the composition and properties of hydrocarbon mixtures such as petroleum fractions with a reduced number of representative compounds that closely match the characteristics of the complete molecular composition of the mixture.

Abstract: Disclosed is a process to evaluate radial turbo-machinery equipment performance for comparison between “actual” (measured or calculated) performance and “target” (calculated) performance and, optionally, to provide a real-time monitoring system for equipment performance and means for analysis and optimization.
