The main objective of this research project is to increase the efficiency of GE centrifugal compressors by optimizing fuel consumption. Approximately 39% of ADNOC Gas Processing’s compressors that are currently in operation are centrifugal compressors manufactured by GE or companies acquired by GE. Other compressors are from companies such as Siemens and MHI. The optimization of these compressors is to be accomplished using Model Predictive Control to solve for operating points for which at steady state the fuel consumption is minimized. Model predictive control solves an optimization problem to calculate the optimal control signals. At each step in the controller operation, an optimization problem is defined based on a mathematical model of the system.
