Multivariable Predictive Control:The Scope is Wider Than You Think

By Rafael Lopes, Robert K. Jonas and Alexandre Dalmax Honeywell International |

More and more, the chemical process industries (CPI) are seeking out the benefits of flexible production and maximizing energy and material recovery. Process units are becoming tightly integrated, and the failure of one unit can seriously degrade overall productivity. Meanwhile, with the influx of larger and larger scale operations, even small changes in productivity can seriously affect profitability. While the petrochemical industries have been successful in using multivariable predictive control (MPC) to manage such complexities, the rest of the CPI leaves room for much wider and more frequent MPC deployment and the higher productivity and lower costs that accompany it. These sectors have been slow to adopt MPC, but that trend appears to be changing. The reliability and amount of automation in industries, such as pulp and paper, and mining and metals have improved. MPC has been successfully implemented in ore grinding, smelting, and in all parts of alumina refining. In the pulp industry, MPC also is now a reality and has been implemented successfully in lime kilns and bleach plants. MPC requirements are to deeply study and understand the process, use operators’ and engineers’ experience, find the key variables and solve…
