Defining Digital Twins in the Context of Process Safety

A digital twin is far more than a 3D model. It is a dynamic, data- driven simulation that continuously syncs with it signal control- contropart thrugh sensors, IoT devices, andd operational data sources. In process safety, digital twins fall into several distrant divories:

Each twin ingests data at intervals from milliseconds to minutes, uses physics-based models or machine learning to simulate behavor, and provides outputs such as alarms, risk scores, or recommended actions. Organizations can implement twins att any scale, from a single column to at an entire refinery, with incremental cott and complex.
