Calculation of equilibrium of hydrocarbon mixtures considering the nonideal nature of phases

Control of Catalytic Divided Wall Column

“…DWC can separate three components at the same time, and it consists of a single shell column and a dividing wall, in which a prefractionator and a main column inside a single structure are set up [3,4]. Petlyuk [5] proposed that DWC is a special structure of thermal coupling columns and the former can be considered equivalent to the latter from thermodynamic perspective without heat passing the wall. DWC is receiving increasing interest in chemical industry due to its potentiality in energy and capital cost saving [6].…”
