Webcontrolled the WABT for each of the two reactor trains between tight operator given limits. In the revamped version, these WABT limits were opened and the controller now gets the opportunity to maximize the WABT (for both of the parallel reactor trains) against clearly defined constraints in the distillation section. WebThis model can be used to estimate the date when the WABT will reach the system’s maximum operating temperature, which will allow for improved maintenance planning. In …

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. WebJul 10, 2024 · The weight-average bed temperature (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 temperature of the large-scale reactor is referred to, WABT was used.
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 ...
