(OP)
We would like to cool coker cutting/quench water below the current 120 - 130 degF to reduce deheading vapor cloud and hot spot eruptions. 90 degF is the target. We are considering a stand alone, direct contact cooling tower, and recycling back to the coke pit maze. Is microbio fouling of the tower going to be a problem? We are also considering instead to divert relatively cold waste treatment feed water (storm, not process) as pit make-up and routing hot surface water to WWTP. Both options rely on temperature stratification in the sump. Any experience with cooling this water?

When you remove the top head (prior to coke cutting), the vapor plume is best managed with an ejector to suck vapors away from the cutting deck.
Cooling the cutting water has no effect on "hot spot eruptions". Good steaming, quench and drain procedures minimize the potential for hot spots.
