Vaporizer bubbling evaporation

2009-04-10View Original

Thread Content

Is the mixture formed by the bubbling evaporation in the carburetor uniform? For example, if the liquid level and outlet pressure of the vaporizer are kept constant, and bubbling evaporation is used (with the two substances being immiscible), and the flow rates of these two substances at the inlet are fixed, then is the flow rate ratio of the mixture at the outlet also fixed?

It seems that the question posed by the original poster is somewhat similar to those in distillation processes; the two substances cannot form an azeotrope (they are immiscible). Volatilization through bubbling occurs at the boiling point of the substance with the lower boiling point, so the composition of the material at the outlet will have a higher proportion of this substance with the lower boiling point, but the overall composition remains unchanged
