In my experience, it took 7 days to start CDU. First, cold circulation for 3~4 days ,then, hot circulation for 3~4 days ,then, load up slowly.

To live CCR and BTX , it took almost one month. When you heat up big column, take care of thermal expansion.

Unfortunately, I don't have documents show detail.

Hi Hoang Nguyen


For your help.


Has your refinery operation manuals to review?
How about records of your refinery startups?
And the technical documentation for consult about this issue.
You need specifically the operation manuals for each units and review and studied it carefully.
You need a technical advisor for this job if your refinery has not experience in complex refinery start ups. This is the cheapest solution. if you think about HSE.


I think this little bit will be useful.


Good luck
