PSE Update: Developments & directions in high-fidelity predictive modelling and its application in model-based engineering in the process industries
PSE is continuing to drive the application of high-fidelity predictive modelling throughout the process industries. MD Costas Pantelides explains why model-based engineering approaches now needs to focus on putting the power of such models in the hands of end users as well as modelling specialists, in order to maximise return on modelling investment. |

Keynote: Implementing a corporate-wide model-based engineering approach in a large organisation
Procter & Gamble faces many challenges in the area of process modelling, not least the fact that traditional simulation tools are not readily applicable to their processes. This means that it is necessary to create fundamental building blocks in the form of models libraries that can be provided to engineering and operations users before applying these address challenging problems. Ben Weinstein describes how P&G has formulated a model-based approach to engineering design and operations and is developing the modelling infrastructure within the organisation to support this. He illustrates this with current work with PSE in creating a comprehensive solids modelling capability aimed at consumer goods manufacture. |

High-fidelity modelling of phthalic anhydride reactor systems: challenges and opportunities
High-fidelity predictive models of tubular reactor systems pose numerous challenges and opportunities when it comes to overall optimisation strategies. Süd-Chemie applies such models to support PA producers in maximising plant performance. The presentation will discuss various aspects of this task, from laboratory through pilot plant to the final commercial plant operation. |

Utilising process modelling to drive yield improvement in an inorganic chemical process
Modelling was used to improve the process yield of a mature chemical process that has undergone decades of continuous improvement but is prone to frequent operations disruptions. The process contains highly non-ideal solutions, a blend of batch and continuous unit operations and many recycle streams. Determining the impact of key variables on a critical side reaction has allowed design of a relatively low-cost process change to improve yield. |

Simulation and dynamic optimisation of products blending
Dynamic optimisation is used to optimise the cumulative production of certain final products obtained by blending different product streams in which composition and flowrates vary over time, taking into account process and hardware limitations and product specification constraints. The optimisation considers a time horizon during which a significant change in composition of the streams takes place. |

Modelling of a Fischer-Tropsch three-phase slurry bed GTL reactor
The F-T slurry bed reactor is a complex operation whose design benefits significantly from the application of detailed modelling. This presentation describes the modelling of the reactor in gPROMS and – as covered in the joint PSE-TOTAL-Invensys presentation at 2009 AICHE Annual Meeting – its deployment in PRO/II. With acknowledgement to TOTAL and Invensys |

Whole plant design optimisation for a large-scale process
PSE worked with Repsol to perform a simultaneous design optimisation of a process involving a multitubular reactor coupled with a separation section that included a number of distillation columns, two with chemical reaction. Mixed integer optimisation techniques based on an economic objective function and applied simultaneously to the entire plant resulted in substantial CAPEX and OPEX savings. |

Refinery preheat train modelling, simulation and energy optimisation –
the next generation
New model-based techniques for optimising refinery preheat train operation are being applied to large refineries, resulting in significant bottom-line gains. This presentation describes the theory, its implementation within the gPROMS framework, some exciting results of initial applications with two major oil refiners, and benefits. |

SESSION 3 – gPROMS & model-based engineering developments |
gPROMS v3.3 – towards a tool for Engineering
With v3.3, gPROMS takes a further step towards becoming a process flowsheeting tool for engineers while retaining – and extending – the custom modelling power that makes it the tool of choice for expert process modellers.
Major new features include model initialisation procedures, more sophisticated specification dialogs and a graphical task language for describing complex operating procedures.
This session takes a look at the new capabilities and their potential for driving productivity across the organisation. More in-depth information on some of the new features can be found in the workshop sessions of Wednesday 15 September.

Exploring the space for innovation in Real-Time Dynamic Optimisation
While commercial RTO/MPC engines base their applications on low-order empirically-determined process models, the space for innovation in APC is far richer, allowing for different model formulations, control problem specifications and solution methods. In this presentation PSE shows how first-principles process models can deliver value when embedded in a prototype engine to solve complex industrial control and optimisation problems in real-time. |

Unlocking the potential value of corporate knowledge in legacy models
Much valuable corporate knowledge is locked up in legacy programs across the process industries. Converting legacy code to gPROMS allows easy maintenance, extension of capabilities, addition of dynamics and use of optimisation, and the potential for application by users throughout the corporation. This presentation describes various applications, including Gas-to-Liquid Fischer-Tropsch reactors, evaporators and multi-stream heat exchangers. |

Moderated discussion
Where to from here? Future directions for high-fidelity predictive modelling
With the enormous strides that have been made in high-fidelity predictive modelling to optimise many different aspects of process design and operation, where does the technology and its application go from here? The panel of experts will provide their views briefly, followed by a question-and-answer session. |

Dynamic modelling of a new polylactide (PLA) production process
Purac and Sulzer Chemtech are collaborating to develop a new process based on static mixer technology for production of PLA from lactide. This presentation describes how model-based techniques allow the use of lab data for process design, to better understand and predict process behaviour and speed-up and optimise the design of PLA production plants. |

Model-based CAPEX decision support for large-scale surfactant plant
Procter & Gamble is using modelling extensively to underpin key commercial capital decisions related to the design and operation of surfactant plants. This has involved a substantial activity focused on creating a modelling infrastructure in this 'non-typical' application area, including development of model libraries, large-scale flowsheet development and deployment across engineering and operations departments. |

Energy efficiency in waste water treatment plants: optimisation studies and process analysis
Veolia R&D and Ecole Polytechnique Fédérale de Lausanne (EPFL) are working together to optimise the energy efficiency of an industrial waste water treatment process. Plant-wide models of the process, which includes activated sludge reactors coupled with an anaerobic digestion reactor, are used within an optimisation framework to minimise energy consumption taking into account the bio-chemical transformations occurring inside the bio-reactors. |
