Light Naphtha Sulphur

[Hedewandro Lucredi]

What is it the FCCU process variables to reduce Sulphur in the Light Naphtha ? Besides feed quality, naphtha end point. We are processing a huge amount of heavy coker gasoil in our UFCC (+/- 25 % of the feed). How Can I reduce the suphur in the Light Naphtha by changing the process variables ?

You generally cannot change the sulphur content by changing process variables. The sulphur needs to be reduced either upfront with treated feed or processing the gasoline to remove the sulphur.
