WebAug 15, 2014 · Usually it just means to supply thermal heat to a solution or a solid. For example, heat the flask containing a solution of potassium chlorate. A more detailed experimental procedure would specify how much heat and for how long (e.g. dissolve the potassium chlorate in water and then heat to reflux for 1 hour). – ron. WebThe section efficiency in a distillation column is related to the tray efficiency by (2): When the equilibrium line is steeper than the operating line, as is typically the case for the stripping section of a column, the stripping factor is greater than one and the section efficiency is less than the tray efficiency.
