2022, Chemical Engineering Research and DesignCitation Excerpt :If foam forms in the evaporators and rises up to the separation columns, this can lead to premature flooding of distillation columns, increased pressure losses, reduced throughputs and a reduced separation performance due to backmixing (Lieberman et al., 1989). In the worst case, the occurrence of undesired foam leads to a complete shutdown of the plant operation (Chen et al., 2007; Kister, 2003; Leuner et al., 2020; Senger and Wozny, 2011). Foam-prone circumstances exist during gas/liquid contact when the phase interface is stabilised by surface-active substances (Senger and Wozny, 2011; Thiele et al., 2003).
