Abstract: The present invention relates to a system for the computer simulation of a chemical process comprising a plurality of functional modules for completing respective simulation levels of said chemical process, a storage module for storing experimental data relating to chemical species in a data structure that can be used by at least one functional module, a performance evacuation module, in which said process is defined by a set of files shared by ail the modules of the system, each file comprising a description of a raw material and a description of a decomposition of this raw material into chemical species, said files being the inputs and the outputs of said modules of the system, the decomposition into chemical species being preserved throughout the processing operations.

Abstract: A system for computer simulation of a chemical process includes at least a first operation which is described by an explicit algebraic equation. The system includes a receiving module for receiving the first explicit algebraic equation, a processing module which is configured to convert said explicit algebraic equation into an algebraic/differential equation and a resolution module which is configured to solve the algebraic/differential equation.
