화공에서 Yield 의 정의

1. Recation yield

<batch reactor>

 

  Y_D = N_D / (N_R0 - N_R)

Nd : moles of desired product

Nr0 : moles of initial reactant

Nr : moles of final remained reactant

 

<flow reactor>

  Y_D = r_D / -r_R

 

 

2. Plant yield

 

 Plant Yield = (mols D produced)×(stoichiometric factor)/(mols R fed to process)

3. percentage yield

 

Amount of product obtained     x   100

Theoretical maximum product
