Abstract (en)
[origin: WO2018024711A1] The present invention relates to a method for controlling a concentration of a first component of a rectification column for separating a binary mixture of the first component with a second component on the basis of temperature measurements, wherein a control path defined by temperature sensors (T3, T2, T6) arranged in the longitudinal direction of the column is linearized with the aid of an estimated temperature profile, wherein a real temperature profile T*(h), determined by means of the temperature sensors, is approximated by a function T(h) in dependence on a column height h, wherein the column is divided into two sections along the column height h and the function T(h) is defined section by section on the basis, in each case, of a logistical function.
