Hello everyone,

 

We have built a static model of an atmospheric rectification column that converges. We need to run a dynamic simulation of the crude switch on this model. When converting the model into a dynamic mode, PetroSIM demands additional specifications. The problem is with the two separators: condenser and stripper. Why do flow specifications need to be added in dynamic mode that were not necessary in the static mode?

 

Thanks in advance

Every dynamic simulation computer program I am aware of is based on internal instructions and procedures to generate predictive solutions from input data. The required input data is either supplied by the user or derived from some other source. Because of the additional time-based parameters needed for dynamic simulation, the solution has an additional order of magnitude complexity. Static mode can ignore equipment volumes to reach solution since the answers are for steady state at a distant future. Dynamic models must also predict the rate of change which is very dependent on flow rate and volumes. The software company should be glad to help with specific questions about using their product.
