BurninghamOttoMethod Implements the Burningham–Otto Sum-Rates (SR) method for solving the MESH equations of absorption and stripping columns. Unlike the Bubble-Point method, the SR method tears on stage temperatures rather than compositions, making it more suitable for wide-boiling-range systems.
NaphtaliSandholmMethod Implements the Naphtali–Sandholm Simultaneous Correction (SC) method for solving the full set of MESH equations of distillation, absorption, and stripping columns. All equations (material balance, equilibrium, summation, and enthalpy balance) are solved simultaneously using a Newton–Raphson linearisation with Jacobian matrix evaluation.
Tomich Provides the Tomich Tridiagonal Matrix Algorithm (TDMA / Thomas algorithm) for solving the linearised MESH material-balance equations in stage-wise distillation and absorption column calculations.
WangHenkeMethod Implements the Wang–Henke Bubble-Point (BP) method for solving the MESH equations of distillation and absorption columns. The method iteratively adjusts stage temperatures via bubble-point calculations and solves the linearised material-balance equations with the Tomich tridiagonal-matrix algorithm.
WangHenkeMethod2 Implements a Modified Wang–Henke Bubble-Point (MBP) method that enhances the standard BP approach with per-stage flash calculations for improved robustness in systems with non-ideal behaviour. Uses the Tomich TDMA for the material-balance equations.
