Analyzing the value of first-principles dynamic simulation

Use it to test new control schemes before implementing them in a plant

Control engineers can make practical use of first-principles dynamic modeling technologies, which are now becoming mature enough to provide significant value for control purposes. The modeling efforts used in this case study have been analyzed from the control engineer's perspective, including a discussion of best practices to optimize the use of internal resources. A first-principles dynamic model of a depropanizer column is used to test and to confirm a new proposed operation and control mode that improves the steam consumption and the stability of the column. The previous column operation mode was not suitable for the planned advanced process control (APC) project in the area of this un
