Abstract

A rigorous dynamic simulation is performed to find optimal operating conditions of a crude distillation unit with 56 trays and 65,000 barrel per day capacity. The model includes not only mass and energy balance equations but also nonlinear equations capturing the fluid behavior in the column such as downcomer load, jet flooding, hole velocity limit and downcomer backup. Discrete behavior of pump and heater on/off, valve open/close are also included. Hundreds of thousand differential algebraic equations(DAEs) are set up and solved by gPROMS simultaneously. As a result, the dynamic behavior of the unit during the starting and shutdown procedure is fully understood.
