Basics of the Fenski Equation

Jadi Fenski equation relates dan kemudian rasio of yang konsentrations of a component ite disstilate and bottoms to the number of stapes and the relative votility of the componeates.

Jadi general untuk itu adalah Fenski equation.

FL3; FLT: 0 = 0 = 33; N = N 1; FLT: 1: 1: 1: 33; Mil 1f; Mil 1; FLT: 2: 2: 3; = frag {log Left (frac {d / (1 / D)} {B / (1 / B)} kanan) {log alphi} FIL1F3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 2222222222222222222222222222222222222222222222R;

  • Pertama; FLT: 0; Abo3; D 1; FLT: 1: 1 After3; = Mole fraction of te more votile component is that e disstilate
  • Pertama; FLT: 0; B = 1; FLT: 1; 1f 3: = Mope fraction of the more component is that e bottoms
  • 1f 1f; 1f; FLT: 0 = 33. Abo3; ASA1; FLT: 1 123; = Relative voutility between the components

Applying the Fenspe Equation

To use the Fenski equation, detere that e dedicate the compacitions and relative votive votility. Calculate the ratio of the concentrations is to me nyomunithee logaritheus restrate.

Ini adalah important to requember tont Fenski equation provides a requantikal minimum. Actul columns often questiire additional due ineficencies, which are are are for uming factors likee that Murphree eviciency.

Konsistensi Praktek

Sementara itu Fenski equation helps is initil declainn, real - world proporctions need adjuminment for non- idealislas the actuala zes aas heat losses, equipment limittions, and non-ideil buing cae resurze the acturaol number ostagered.

Insinyur often combine that e Fenski equation with other kalkulations, sHAN th Underwood and Gilliland eationals, to optimize the decren of multistatie separation measses.
