Description
Estimates binary interaction parameters using available correlations:
- Nikos (PR, temperature-dependent): for N2-HC, CO2-HC, CH4-HC pairs
- Elliot-Daubert (SRK): for N2-HC, CO2-HC, H2S-HC, C1-heavy pairs
- Chueh-Prausnitz: from critical volumes (individual pairs)
The Kij.Matrix function generates a full N×N symmetric matrix that can be passed to Flash, BubbleP, and other calculation functions.
