Use of the Taylor Series as a Convergence Technique for the Solution of Multicomponent Dew Point and Flash Vaporization Problems
Separation of non-electrolyte components at low pressures by distillation requires the column feed to be characterized as to the amount of each phase, composition, temperature, and pressure. For multicomponent, non-ideal solutions this requires solution of simultaneous, non-linear equations. This thesis demonstrates the use of the Taylor Series to linearize these equations while employing an outer bi-section loop to determine the temperature, pressure, or fraction flashed given one of these latter variables.
