ABSTRACT:
Control of a fractionation column is maintained by obtaining two differential temperatures between pairs of selected temperature-sensing points along the height of the column. One pair of temperature sensors is vertically-spaced above the feed tray, while the second pair is below the feed tray. Signals representing the sensed and measured delta-T's are employed in conjunction with a signal representing the flow rate of the feed stream in regulating the quantity of reflux to the rectification zone and in maintaining the required reflux to feed ratio.
