In tubular reactors inside a cracking furnace, heat transfer, thermal cracking reactions and coke buildup
take place and closely interact with each other. It is important to understand the process and optimize
its operation. A 1-dimensional (1D) pseudo-dynamic model was developed based on first principle and
implemented in gPROMS®. Coke buildup inside the tube wall was also accounted for. The model was
validated dynamically. The impact of process gas temperature profile, and constant tube outer wall temperature
profile on product yields and coking rate are assessed. Finally, dynamic optimization was applied
to the operation of this tubular reactor. The effects of coking on reduction of production time and the
decoking غير مجاز مي باشدt have been considered. The tube outer wall temperature profile and steam to propane ratio
in the feed were used as optimization variables. Dynamic optimization investigation indicates that it can
improve operating profit by 13.1%.
