(76a) The Role of Process Simulation in the Digital Transformation

While Digital Transformation hits every corner of industry, the process engineering discipline has been largely excluded from this trend so far. PwC foresee that for process licensors / EPCs, data driven digital services can displace process technology as a differentiator¹.

The objective of this presentation is to provide an overview of the obstacles to Digital Transformation for the process discipline and explain how these can be overcome. A special emphasis will be given on the role of the process simulation tool (white box modelling) as a catalyst for transformational change.

The presentation will examine several challenges specific to process engineering:

1) According to DECHEMA, one major obstacle for digital transformation is the division of process simulators into single-purpose point solutions. Today, separate models may be created – often in different tools – for process design, control strategy design, operator training simulation, performance monitoring and online optimization. This drives up the total cost of modelling to a degree than can become prohibitively expensive. One single model should be able to cover the entire plant lifecycle from idea to operations².

2) Engineering disciplines, other than process, collaborate closely with database-driven tools and assured workflows. Process simulators are typically poorly integrated into this workflow, and if so, with a single directional information flow. This lack of integration makes it nearly impossible to break down silos and enable new ways of working, like the agile development methods that have transformed software engineering.

3) Over the decades, legacy process simulators got overloaded with niche features and functions only usable by experts. This bloat makes them not suitable for automation and operations.

4) The potential benefits of Artificial Intelligence and Machine Learning for process engineering are not widely understood. Appropriate black box tools are not deeply embedded within white box models.

More recently, stakeholders see the Digital Twin as the most important building block for Digital Transformation of the process industries. The process discipline must be a central part to this transformation³.

While legacy simulators are well-suited to accurately simulate processes, their decades-old architectures mean they are not ideal to serve the entire plant lifecycle and support the Digital Transformation. We will use the AVEVA SimCentral Simulation Platform⁴ as an example of how the identified obstacles can be overcome with a next generation process simulator. Case examples from leading EPC and Operating companies will be outlined and will serve as a way to explain the related benefits.
