Prediction of binary diffusion coefficients in supercritical CO2 with improved behavior near the critical point

- Predictive model for tracer diffusivities (D12) in SC-CO2, accurate far and near the critical point.
- Model comprehends background (regular) and singular (critical enhancement) contributions.
- Average error of 6.20% achieved with 149 systems and 4469 data points totally.
- A spreadsheet for the prediction of D12 in SC-CO2 is provided in Supplementary data.
