Dynamic simulation for process design. C.A. Depew and R.B. Nielsen. Hydrocarbon Processing, July 1996, 75(7), 67--75.

Dynamic simulation is recommended as a process engineering design tool. It predicts process and control responses to various upsets as a function of time and determines the reliability and safety of unit designs before capital expenditure is required. The technique is also used to evaluate startup and shutdown sequences. Typical dynamic simulation applications in refinery operations include hydrocracker/hydrotreater depressurizing, distillation/fractionation relief load reduction, and heat exchanger tube rupture analysis. Features of these operations are described and illustrated. Other applications are control analysis of refinery steam production and distribution systems, compressor surge control analysis, vacuum unit transfer line design, cryogenic depressurizing studies, and distillation column control analysis. 9 refs.
