Benzene at Cracked Naphta

[Hedewandro Lucredi]

We are having benzene at cracked naphata in the range of 0.9 % . Is it number “normal” ? How can I reduce benzene in our FCCU ? what are the process variables in order to reduce benzene ? Our feed is Straight Vaccum Gasoil, Heavy coke gasoil and light coke naphta

We still have benzene at light naphtha. It seems to be from the feed more lighter than usually is. How can I reduce the benzene in the light naphtha ? What are the process variables that affects benzene in the naphtha?
