In the heavy crude oil upgrader I used to work, we had emergency steam on the atmospheric distillation, vacuum distillation and coker heaters.
 
However, we had one emergency shutdown event where the emergency steam line to the vacuum heater had condensate (water) in it because of non working steam traps.
 
The result was a damaged packing in the vacuum tower, and failed piping support guides on the transfer line (between the heater and the tower).
