Discharge capacity of plate heat exchangers. This is a department alternative to the requirements in ANSI/IIAR 2 section 11.2.7:
The minimum required relief device capacity for a plate heat exchanger based on an external heat addition scenario may be calculated in accordance with the following equation:
where:
Cr,plate HX = minimum required relief device capacity for the
plate heat exchanger (lbm/min of air)
f = relief device capacity factor
L = length of the plate pack (ft)
W = width of the plate pack (ft)
H = height of the plate pack (ft)
