Abstract
A method of reducing plant emissions includes providing a MPC model for a flaring process including one-to-one models between controlled variables (CVs) including a smoke count and/or a flare count (CV) and a noise level (CV), and flow of assist gas as a manipulated variable (MV) and another process gas flow as a disturbance variable (DV). The MPC model receives sensed flare-related parameters during the flaring process including a measure of CV(CV*) and CV(CV*). Provided CV* is above a minimum setpoint for CV(CVsetpoint) and CV* is above a setpoint for CV(CVsetpoint), the flaring process is automatically controlled using the MPC model which determines an updated flow setpoint for MV from CV* and CV*, the CVand CVerror, and the identified one-to-one models.
