Brazed Aluminum Heat Exchanger Dashboards

Sjoerd Hoogwater, Consulting Engineer, Phillips 66

Brazed aluminum heat exchangers (BAHX) allow high rates of heat transfer, but the equipment is susceptible to mechanical failures and internal/external leaks. As recognized by BAHX manufacturers, thermal cycling and high temperature differentials between adjacent streams can cause fatigue on the equipment and contribute to equipment failures. Seeq functionality was utilized to calculate the historical and current thermal cycling and temperature differential magnitudes on each BAHX across the fleet.
