WebEOR WABTs are known and depend on design specifications or process limitations. To meet the cycle length, SOR WABT of the P/T can be determined from the expected deactivation … WebInside reactors during normal operation, fluid flow is the only significant way to remove process heat. Uneven fluid flow can impair performance. It can lead to hot spot formation, which can jeopardize process safety and catalyst life. ... The data shows that the operating WABT is reduced significantly. Fig. 23.8. Graph comparing WABT, before ...
