thanks all for the input.. does anyone uses the blowdown settling drum water for quenching? if yes, what is the limit in temperature at coke drum when intorducing this water? we’d recently switch to open top tank (by incident), what we see is that the the water tank accumulates some oils (over the time), which we perform daily skimming. We are thinking of using demulsifier in the the settling drum to help separate water and oil. Any good chemicals?
