Integrated Scheduling and RTO of RGP with MPC and PI Controllers
This paper proposes an integrated framework of scheduling and real-time optimization (RTO) of a refrigerated gas plant (RGP). At the top layer, a high fidelity dynamic model of RGP is subjected to scheduling of plant operating mode from natural gas liquids to sales gas, and vice-versa. Set points fr...

| description | This paper proposes an integrated framework of scheduling and real-time optimization (RTO) of a refrigerated gas plant (RGP). At the top layer, a high fidelity dynamic model of RGP is subjected to scheduling of plant operating mode from natural gas liquids to sales gas, and vice-versa. Set points from mode scheduling are passed down to the steady-state RTO layer. Modeling mismatch is minimized by rigorously exchanging values of key variables between dynamic and steady-state models. Optimal trajectories of set points are obtained using sequential quadratic programming algorithm with constraints. These trajectories are disjointedly implemented by model predictive control (MPC) scheme and proportional-integral (PI) controllers for comparison. Four case studies for each mode scheduling are performed to illustrate efficacy of the proposed approach. |
