Norm -> Square root of the sum of squares of the departure of the VLE equations (residuals) of the tower. The smaller the norm equates to solution confidence
Residual -> The result of the tower equation with the largest deviation from 0 (0 implies solved).
VLE -> Sum of Yi/Xi of all species Y – Vapor : X – Liq 1
M-Balance -> Mass balance across tower Out - In
H-Balance -> Enthalpy Balance across tower Out - In
Sumx+Sumy -> MBG group balance across tower Out - In
