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. 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 incheon frigate
