It is important to understand the process and optimizeits operation. A 1-dimensional (1D) pseudo-dynamic model was developed based on first principle andimplemented in gPROMS®. Coke buildup inside the tube wall was also accounted for. The model wasvalidated dynamically. The impact of process gas temperature profile, and constant tube outer wall temperatureprofile on product yields and coking rate are assessed. Finally, dynamic optimization was appliedto the operation of this tubular reactor. The effects of coking on reduction of production time and thedecoking cost have been considered. The tube outer wall temperature profile and steam to propane ratioin the feed were used as optimization variables. Dynamic optimization investigation indicates that it canimprove operating profit by 13.1%.
