is investigated.Objective – increasing the productivity of the process of rectification and reducing the energy costs by using mobile control actions and a multi-criteria approach to the calculation of their optimal values.
boundary of the working region of the rectifying column in the coordinates of traditional control actions is suggested to be carried out by the method of secants. Since the magnitude of the desired mobile control action can only take on discrete, integer values, a scanning method is proposed to solve the optimization problem.
productivity achieved by the use of mobile control actions is 1 to 5%, while the heat savings in the reboiler of the column are 6–8%.
two degrees of freedom, modeling of transient responses in rectification columns at mobile control.
