Hi, 

I have a problem for calculating the firewater demand in fire scenario in a plant. There are columns, vessels, heat exchangers, reboilers and aircoolers in the plant. Which equipment shall be taken into account for calculating the firewater. 

Please note that in NFPA 15, only mentioned that vessel areas should be considered. What about other types of pressure vessels, like reboilers, exchangers, etc.? 

 

Thank you for your help.

If you are focused on prescriptive methods, refer to API 2001.

 

If you want to look at real life scenarios (i.e. considering actual configuration / volumes of your plant and equipment and what could go wrong), organize a team consisting of Process Engineer, Tech Safety, Operations, and identify realistic fire scenarios - consider how far they could possibly escalate. Then, design the fire protection system capable to cope with these events.

Hi,

Consider the documents attached.

Past projects in China and Thailand, requirements were 2000 m3 and 1300 m3 capacity, for 2 hours operation.

For China a spent water pond for 2000 m3.

Note:

You should consult also your safety bureau and /or the fire brigade and/or the Insurance Broker in charge of the facility where the project is being installed.

Good luck

Breizh
