Zusammenfassung:	An advanced control method for the butadiene rectifying apparatus consisting of the first and the second rectifying towers include such steps as measuring the real-time data of the first rectifying tower, filtering, running the soft measuring model, inputting the filtered data to it to obtain the water contant of its tower still and the methyl ethyne content of its tower top, and in-line closed-loop optimizing control on the basis of DCS.
