Optimizing an energy-intensive distillation section (Depropanizer, Deethanizer and Propane–Propylene Splitter) critical for product quality and profitability, while improving reliability, measurement accuracy, and early detection of operational issues.
Hydrogen plays a critical role in refinery and petrochemical operations, directly impacting process performance, operating costs and plant flexibility. However, managing hydrogen networks efficiently across complex industrial facilities remains a significant operational challenge.
High-fidelity Aspen HYSYS Dynamics models of the three major distillation columns of a Propane Dehydrogenation (PHD) plant were transformed into an online digital twin, connected to plant data every 2-3 seconds and running for more than a year. Discover how the twin provides virtual sensors, analyzer backup, flowmeter corrections, instrument anomaly detection, flooding analysis and product quality verification. It has also been extended to rotating equipment, exchangers, and emissions KPIs, delivering measurable reliability, energy, and quality benefits.
Dynamic process simulation is increasingly being used in the assessment of flare systems to provide a more accurate understanding of system behavior and to identify potential constraints. For complex refinery units, its role becomes even more crucial, ensuring process efficiency and operational safety.
In this session, we have explored how Inprocess applies Steady State and especially Dynamic process simulation techniques to analyze flare loads and flare network behavior. Learn how our expertise has helped clients identify hidden constraints, optimize system performance, and reduce CapEx spending —without compromising the plant safety.
In this webinar, Jaume Bagasse, our Senior Process Simulation Engineer, walks you through our approach, featuring a case study on the Cold Box within a Steam Cracker Unit.
The Multi-Purpose Dynamic Simulator (MPDS) introduces an innovative approach that extends the application of dynamic process modelling across the design, commissioning, and operational phases, maximizing its value throughout the plant lifecycle.
This white paper from Inprocess introduces the Multi-Purpose Dynamic Simulator (MPDS) approach—demonstrating how a single dynamic simulation model can be reused throughout the entire lifecycle of a process facility. From early engineering and virtual commissioning to operator training and real-time operational support, MPDS helps reduce project risks, improve safety, and maximize the return on simulation investment.
This webinar showcases how Ascensus Specialties has achieved significant benefits by implementing an Operator Training Simulator (OTS) for their hydrogen production plant.
This webinar showcases validation and development of a dynamic simulation model as well as identification of bottleneck and critical points.
