RE: Blowdown/quench system operation

#5452

with cold weather or not these finfan are going to get clogged/plugged with wax, when the temperature is below 350 F, we have implemented a routine procedure to avoid these plugging or to kept operational
to determine which are blocked, it’s as simple as going to the field and touch the box heads, the procedure is at the stage of stripping / cooling to the blowdown, we turn off a bay, we close the louver and we put the heat exchanger (steam coiler), we do this routinely to all finfan everyday

we do it this procedure in all our coker and operate very well

best regards
