Hi Evan,

Thanks for the response. We are using 600k cSt antifoam and our refinery does not process extremely heavy feeds so it sounds like the 1-lb of AF per 1000 bbl of feed should be a good general guideline for our unit.

I want to make sure that I am doing the calculation correctly. For example, if the unit was running 16,000 bpd, following the rule of thumb we would need to use 16 lb of antifoam in a day, correct?

By my calculations for our DCU, we’re averaging ~14 lb AF per 1000 bbl of feed per day.

This doesn’t seem correct because it does not feel like we are using an excessive amount of antifoam for the unit.
