Pressure-compensated temperature control in rectification column [PDF]
CHEMISTRY AND CHEMICAL ENGINEERING, 2020 The focus of this work is to study the control of a rectification column (RC) for separating n-butane (nC4) and n-pentane (nC5) mixtures. Two control structures based on conventional temperature control (TC) and pressure-compensated control (PTC) structures are studied and compared using Aspentech software.

Investigation of material cost of a propane-propylene rectification column [PDF]
Multidiszciplináris TudományokIn this study a propane-propylene rectification column was investigated in terms of diameter of the column, number of trays, reflux ratio and the construction material costs of the column. During the calculations the reflux ratio was modified between 8 and 30. The chosen material of the column and trays was 1.4404 grade austenitic steel.
