Definition parameters of mathematical model of the distillation process ethanolamine
The problem of parametric identification of the mathematical model of the process of rectification of ethanolamines in the known structure of the object and the unknown parameters of the process of mass transfer in the system of diethanolamine-triethanolamine. A mathematical model of the process is an analytical description of the fundamental laws of mass transfer. The unknown parameters of the model proved to surround the mass transfer coefficient and the coefficients according to a formalized, describing the vapor-liquid equilibrium in the system, diethanolamine-triethanolamine. Directly measure these parameters is not possible. Therefore, it was proposed settlement and experimental identification method to estimate the parameters of the model based on minimizing the sum of squares of the differences between the calculated and experimental values of the output of process parameters on a series of experiments. Identification results of the experiment conducted on an industrial plant for the separation of a mixture of diethanolamine-triethanolamine packing type distillation column. Testing of the developed mathematical model and prove its value, and shows the future direction of its use in optimal control problems.
