Hi there,
In a complex petrochemical plant with a lot of piping, it's obvious that modeling all of the piping in a CAESAR II job is not a wise approach. But, is there any guideline/s for selection of lines that fall into a single job? Considering a pump station within a complex refinery, which lines and to what extent shall be selected for the modeling? I should be grateful if you answer this question by description of corresponding boundary conditions at the peripheries.
