The products  of  the  process  were  heavy  naphtha,  kerosene,  diesel,  atmospheric  gas  oil and reduced crude.  However, the dynamic and multivariable nature with strict quality was makes it difficult to operate the process units steadily.  More, the dynamics of CDU are complex  due  to  its  complex  vapor-liquid  equilibrium  relationships.    It  is  necessary  to predict  the  new  steady-state  values  for  any  changes  in  the  operating  conditions. This research  aims  to  develop  a  steady-state  model  for  CDU  based  on  the  fundamental modeling  approach.  The  simulation  was  carried  out  in  Aspen  Plus.  The  effect  of  feed flow  rate,  feed  composition  and  steam  flow  rate  on  product  compositions  and tray temperatures  were  studied.  The  results  were  compared  with  the  data  available  in  the   literature and the accuracy of the model has been proved. 0aDistillation apparatusxDesign and construction
