A computer-implemented method and system for modeling chemical reaction in a chemical reactor is disclosed. The method and system employ a molecule-based equation-oriented approach. Local-stored pre-estimated thermodynamic properties are generated based on a set of homologous series of compounds defined by the method and system. A set of reaction rate equations is automatically generated in equation-oriented format based on the defined set of homologous series of compounds, a system-defined set of permissible reactions, system-defined properties of the reactor compounds, and the locally-stored pre-estimated thermodynamic properties. The automatically generated set of reaction rate equations forms the model of chemical reactions in the chemical reactor.

A method for controlling lingerature of a chemical reaction. Changes in mass of a chemical reaction are monitored and are used to calculate a lingerature of the system. The reaction can be maintained at a desired lingerature (?) by selective addition or removal of heat or by adjusting the surface area the reactants are exposed to during the reaction. The disclosed method is useful for reactions that occur at non-equilibrium conditions where any measured lingerature would presume steady-state conditions.

Devices and methods for controlling the properties of chemical species during time-dependent processes. A device includes a reactor for containing one or more chemical species of a time-dependent process, an extraction pump for automatically and continuously extracting an amount of the one or more chemical species from the reactor, one or more detectors for measuring property changes of the one or more extracted chemical species and generating a continuous stream of data related to the one or more property changes to the one or more chemical species during a time interval, and a process controller configured to fit the continuous stream of data to a mathematical function to predict one or more properties of the one or more chemical species at a future time point and make one or more process decisions based on the prediction of one or more properties at the future time point.

An actuator is provided that includes a housing, a linear actuating shaft disposed within the housing, a piston coupled with the shaft, and a fluid barrier disposed on an end of the shaft and encircled by the piston. The piston is movable longitudinally between an extended configuration and a retracted configuration upon rotation of the shaft. The fluid barrier engages an inner surface of the piston preventing fluid communication across the fluid barrier. The fluid barrier has a shaft engaging side which receives the shaft and a fluid facing side. A cavity is formed between the piston and the fluid facing side and expands when the piston moves to the extended configuration and contracts when the piston moves to the retracted configuration. A port is disposed in the piston and extends from the cavity to external the piston thereby permitting fluid communication between the cavity and external the piston.

A method for controlling lingerature of a chemical reaction. Changes in mass of a chemical reaction are monitored and are used to calculate a lingerature of the system. The reaction can be maintained at a desired lingerature () by selective addition or removal of heat or by adjusting the surface area the reactants are exposed to during the reaction. The disclosed method is useful for reactions that occur at non-equilibrium conditions where any measured lingerature would presume steady-state conditions.

A project planning system for creating a program for monitoring exothermal reactions in a reactor, wherein in order to create the program the project planning system provides at least one first functional module with a mathematical module for determining a maximum temperature and/or a maximum pressure in the reactor in the case of a continuous reaction, based on measured values and based on material data of components in the reactor, preferably by determining concentrations of components in the reactor, and at least one second functional module for determining the material data, in particular a heat capacity, density, vapor pressure, conductivity, solubility and/or viscosity of one or more components in the reactor, where the program is suitable, in particular, for implementation in a safety-oriented, memory-programmable controller.
