Reply to ‘Comment on “Vapor–Liquid Equilibria in Porous Media”’ We would like to thank Drs. Shapiro and Stenby for the attention which they have given to our article [1]. First of all, we are glad that they recognize the experimental data as worthy of interest. There is a dearth of such results in this area. Validation of model predictions with experimental data is a key tenet of our work. Secondly, they are correct in pointing out that there are significant differences between the approach they presented [2] and that which we presented [1]. However, we believe that our “error” was calling our model a “modified version” of theirs. Although their work was seminal in our thinking and we wished to honour that, in retrospect, we should have limited ourselves to giving them credit at the appropriate point in the text. We will not commit this mistake again. The differences between the two approaches warrant that we do not call our work the “modified SS model”. Using the Shapiro and Stenby article [2] as a point of departure, we had gone further by introducing the PRSV equation of state to correct for pressure–volume effects in the vapour state. This treatment allowed us to predict results borne out by experimental work. References [1] Y.-O. Shin, J. Simandl, Fluid Phase Equilibria 166 (1999) 79–90. [2] A.A. Shapiro, E.H.
