Antifoam injection in feed line (Delayed Coker)

Antifoam injection in feed line (Delayed Coker)

Antifoam injection in feed line (Delayed Coker)

Silicon.based antifoams (PDMS) is routenily injected in the top of coker drums to reduce foam height. However, it has been claimed by some refiners that injecting the antifoam directly with the vacuum residue in the feed line, before entering in the drum, is more efective, with a fast response and a lower dossage required.
Has anybody experience with this kind of injection? If so, which is the optimum injection point and which are the issues that must be taken into account?
Thank you very much for your help
Best regards
