A Review of Plantwide Control Methodologies and Applications

Simple Rules for Economic Plantwide Control

“…Just to mention a few, starting with the pioneering work of Page S. Buckley (1964), are: (Price et al, 1994), (Luyben et al, 1997), (Skogestad, 2004), (Aske et al, 2007). For a more detailed overview of Vladimiros Minasidis plantwide control design methodologies we refer the reader to (Larsson and Skogestad, 2000) and (Vasudevan and Rangaiah, 2012).

Optimal operation of parallel dead-end filters in a continuous bio-based process

“…Due to the absence of a high-fidelity plantwide model, batch-operated extraction tanks and filters, as well as the overall restriction to the filtration-evaporation section, successful complete application of a process-oriented or hybrid (Vasudevan & Rangaiah (2012)) plantwide control structure synthesis method (Luyben et al (1997); Luyben (2012); Skogestad (2004Skogestad ( , 2012; Murthy Konda et al 2005) was deemed problematic.…”

Plantwide Control of Biodiesel Production from Waste Cooking Oil Using Integrated Framework of Simulation and Heuristics

“…A good control system distributes the effects of disturbance(s) to unit operations involved to avoid severe snowball effects. The design of PWC systems for safe, stable, and efficient operation of complex chemical processes has been studied extensively. − Methodologies in these studies can be categorized as heuristics, optimization, mathematical, and mixed approaches . Rigorous mathematical- and optimization-based methodologies are complicated and require extensive computations, especially for complex chemical processes.…”

“…For example, rigorous process simulators can be effectively used to aid in decision making in the selection of suitable pairings of controlled variables (CVs) and manipulated variables (MVs) keeping in mind the PWC perspective, such as product quality, throughput, and inventory control. The integrated framework of simulation and heuristics (IFSH) methodology ,, makes effective use of rigorous process simulators. Another PWC methodology is economic plantwide control. − The IFSH methodology is attractive because it is easy to implement and involves minimal computations other than process simulation.…”

“…The PWC of many industrial processes has been studied so far . Recently, a few articles on the PWC of biodiesel processes have been reported in the literature.…”
