Abstract

The goal of optimization is to determine the best, i.e. the most advantageous state of the system. One of the optimization methods is the scanning method, the essence of which is to sequentially view the optimality criterion at a number of points belonging to the region of change of independent variables, and find among these points one in which the optimality criterion has the maximum (minimum) value. The main advantage of the scanning method is that the use of sufficiently “densely” located points of interest always guarantees the search for a global optimum. At the first stage, scanning is carried out with a large step, then the segment within which the largest value of the function is obtained is divided into smaller segments, a new segment is found, inside which the refined value of the maximum is located. The obtained data on the optimal operating parameters of the process of CO₂-extraction of licorice root are necessary for the engineering calculation of equipment for the implementation of this process, the optimal operating parameters of the liquorice root CO₂ extraction process were determined. In this case, the calculated and experimental values are equal to the extract yield of 35,7678 and 31,60, respectively, which confirms the adequacy of the generalized equation.
