SABIC implemented, in collaboration with Inprocess, an Aspen HYSYS®-based Operator Training Simulator (OTS) that replicates the plant control environment, allowing operators to safely train for disturbances, upsets, start-ups, and other critical operating scenarios.
Discover how Inprocess helped MOEVE Chemicals strengthen commissioning and start-up readiness for its new Isopropyl Alcohol (IPA) plant through an Operator Training Simulator (OTS) developed with Aspen HYSYS® Dynamics.
This presentation shows how dynamic modelling has played a crucial role in supporting the safe expansion of a North American oil and gas facility. These models, continuously updated and refined through four major plant upgrades, helped simulate emergency scenarios, assess flare system performance, and integrate both unit and network responses.
An Operator Training System (OTS) was developed for existing ammonia and urea plants to enhance operator skills and improve safety, availability, and performance. Learn how the implemented OTS effectively replicates plant dynamics, improving operational proficiency, safety awareness, and process understanding, and serves as a valuable tool for engineering and control strategy analysis.
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.
In this presentation, learn how CHS and Inprocess have developed and implemented a digital tool to monitor the performance of heat exchangers and support maintenance planning. Using Aspen EDR in Aspen HYSYS, fouling trends were analyzed to identify units exchangers with the greatest impact on process efficiency and cost. Integrated online with real-time plant data, the monitoring tool flags when equipment performance drops below defined thresholds, enabling dynamic updates to cleaning strategies and supporting data-driven decisions that can increase throughput and reduce downtime, energy consumption, and emissions.
Discover how Twelve, a company producing low-carbon jet fuel from CO₂ and renewable electricity, partnered with Inprocess to develop a comprehensive dynamic simulation and Operator Training Simulator (OTS) based on Aspen HYSYS® Dynamics, supporting the commissioning and operational readiness of this pioneering facility.
Inprocess eposter contribution, in collaboration with Wison Energies detailing the extensive use of dynamic simulation to support the design, commissioning and start-up of a Floating Liquified Natural Gas facility (FLNG)
Inprocess oral contribution to the SLB Users Group Meeting showing an example of an OTS application where the holistic dynamic model contained the subsea lines modeled with OLGA and the processing facilities with HYSYS.
Inprocess poster contribution that explains how our holistic dynamic simulations bridge the gap between upstream and downstream models, offering realistic insights and improved operation strategies.
