Equation of the absorption equilibrium line for hydrochloric acid
Thread Content
How is the equation for the absorption equilibrium line of hydrochloric acid determined? Should we refer to the test data?
By default, it is set to full absorption, and all simulation calculations are performed via direct flash calculation.
The books cover examples where the pressure is low and the concentration is low, cases that conform to Henry’s law; moreover, an equilibrium line equation is provided for each example. Clearly, the absorption of hydrochloric acid does not follow Henry’s law – so how can we determine the equilibrium line equation for its absorption?

Without simulation software, full absorption is assumed by default; is the relationship between y* and x therefore the relationship between the concentration of the acid in question and the concentration of HCl in the saturated vapor?
