The system and method of automated determination of the optimal parameters' values of chemical technology system (CTS) functioning in real time mode. The technical result of CTS optimization consists in determining the optimal values of CTS parameters in real time mode on the basis of the current values of CTS functioning parameters and prediction of the values of CTS functioning parameters through a time interval. The result is achieved by supplementing CTS data array by using a mathematical model, including the thermodynamic process description. On the basis of the obtained data array, a mathematical model is formed, based on a statistical modeling or machine learning, which allows to determine the necessary parameters of CTS in real time mode and the values of CTS parameters through a time interval. Based on CTS description in real time mode and the prediction of CTS state through a time interval, the optimal values of CTS functioning parameters in real time mode are determined.

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.

Some embodiments of the present invention provide components for a serpentine fluid reactor which is optimized for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs. The components are designed by computer modeling the components individually and collectively in which the cross section of flow path is substantially circular under industrial conditions to validate the model design and its operation. Then iteratively the component designs are deformed and the operation of the deformed part(s) is modeled and compared to values obtained with other deformed models until the value of the objective function is optimized (e.g. at an extreme) or the change in the objective function is approaching zero.

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.
