The performance of a fractionation column is typically monitored and adjusted during operation by analyzing product stream compositions, monitoring column temperatures and pressures, and adjusting reflux ratio and reboiler duty. Fractionation columns separate components of a liquid mixture based on their boiling points. Analyzing the compositions of the top and bottom product streams is crucial to determine how effectively the column is separating the components. Gas chromatographs or online analyzers provide continuous monitoring of ....
