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 ... Webtemperature (WABT) was determined from the average of the various temperatures measured inside the length of the reactor. The WABT is commonly used to summarize the temperature of a non-isothermal reactor. In this work, whenever the tem-perature of the large-scale reactor is referred to, WABT was used. 2.2 Single-Pellet-String Reactor

WebAs reactor WABT increases, product sulfur decreases. For example, when processing a 1.1 wt% sulfur LCO blend at 1.0 LHSV (where LHSV = volumetric charge rate/ catalyst volume) at1000 psig and 2100 scfb H2/Oil, prod- uct sulfur drops to approximately 50 ppm at WABT of 629°F, and drops down to approximately 5 ppm sulfur at a WABT of 670°F. WebOct 1, 2007 · Considering all NMs, a 1:10,000 catalyst-to-polymer ratio (far below the industrial minimum), and 0.1 wt % metal loading (all conservative estimates) reveals the scale of the problem: > 350 times...
WebWABT= weighted average bed temperature x i = fraction of catalyst in a given bed ( i) or reactor EIT = equivalent isothermal temperature.
