This flow diagram corresponds to the emergency section of a chemical process. For safety reasons, any relief due to high pressure in the reactor system discharges to this scrubbing section before releasing to atmosphere.
Traditionally the scrubbers have been designed based on a mass balance / steady state flow and assuming that the scrubber reaches a steady state condition.

The objective of this project was to create a dynamic model of this process section in order to simulate a full emergency scenario. The results from this model would be the basis for recommending the most effective way to allow the chemical plant to run at higher rates without overloading the scrubber system.
