thais98 Posted January 30, 2021 Share Posted January 30, 2021 Hello, So, I'm trying to follow the steps from a paper, in order to understand the process they made in the software. Firstly, they injected CO2 fugacity in a water sample and the result is an increase in the CO2 fugacity to 68.88 and an increase in the porosity. On the second step, they stop injecting CO2.From what I understood, the resulted solution of the reaction with CO2 is reacted with the minerals that constitute the rock. Their results showed a big decrease in the CO2 fugacity (from 68.88 to 3), porosity and an increase in the pH. However, when I tried to replicate this second step, I didn't get this result at all. My results indicate only a slight decrease in the CO2 fugacity (from ~68 to 63 ). In relation to the pH, something strange happens, which I couldn't figure out why. There's a increase peak, but not considerable in the pH, then it decreases a little bit and then increases again, but actually it increases nothing, only 0.2. And regarding the porosity, it happens quite the same thing as the pH. I'm not sure what I'm doing wrong, I think maybe there's something to do with the reactants that I added. I'm attaching the file of the reaction of the step 2 I made. Thank you ! fase 1 react luben CO2 mais agua 2.rea Quote Link to comment Share on other sites More sharing options...
