Summary Accurate prediction of carbon dioxide (CO2) solubility in brine is crucial for the success capture and storage (CCS) by means geological formations like aquifers. This study investigates effectiveness a novel genetic algorithm-mixed effects random forest (GA-MERF) model estimating CO2 brine. The model’s performance compared with established methods group method data handling (GMDH), backpropagation neural networks (BPNN), traditional thermodynamic models. GA-MERF utilizes experimental collected from literature, encompassing key factors influencing solubility: temperature (T), pressure (P), salinity. These are used to train validate ability predict values. results demonstrate superiority other Notably, achieves high coefficient determination (R) 0.9994 unseen data, indicating strong correlation between estimated actual Furthermore, exhibits exceptionally low error metrics, root mean squared (RMSE) 2×10-8 absolute (MAE) 1.8×10-11, signifying outstanding accuracy Beyond its accuracy, offers an additional benefit—reduced computational time models investigated, 65 seconds. efficiency makes particularly attractive tool real-world applications where rapid reliable predictions critical. In conclusion, this presents as powerful efficient predicting Its superior existing previous literature highlights potential valuable researchers engineers working on CCS projects utilizing aquifer storage. rates, reduced make promising candidate advancing development effective technologies.

This study focuses on the equilibrium adsorption of diethyl ketone, a VOC widely used in printing industry, activated carbon supercritical CO2 environment at pressures range 10 MPa to 20 and temperatures between 313 K 353 K, which provides wider data for ketone under different pressure temperature conditions allows comparative analysis with other VOCs. It is found that exceeds methyl ethyl probably due differences their respective affinities volatilities fluid context. The Dubinin-Astakhov model was interpret showed an average relative deviation approximately 3.8 % modeled observed values. Additional parameters influenced by density characteristics performed gain better insight into dynamics contribute design improvement regeneration process.
