Abstract: The process of gasoline blending is slowly transitioning from the tank blending to the online blending in China. The effect of the optimization depends on the reliability of gasoline quality measurement and the accuracy of the blending rule. This article analyzes the cascade structure of recipe generations and execution in the blending process, then a new recipe PID control algorithm based on conventional PID control theory is introduced. Said algorithm was tested in a blending of a gasoline pool with streams from RFCC, FCC, reforming and MTBE. Results show that said algorithm can meet the basic quality requirements for online gasoline blending.
