Small operational issues in the sulphur recovery unit (SRU) can lead to higher emisisons — or worse, a frustrating and costly shutdown. Simulation of the SRU can enable more reliable operations and fewer shutdowns through the prevention of issues and quick and effective troubleshooting. In this paper, we present three common operational issues and show how simulation was used to prevent or quickly resolve the situation.

The refining market is ever evolving due to market trends continuously changing. Typically, refiners use spreadsheets to develop a schedule, but are often limited to time-based scheduling due to spreadsheet limitations. In Aspen Refinery Multi-Blend Optimizer, schedulers use rundown components continuously, while respecting tank inventories and constraints, to generate a refinery-wide blend schedule on a single database.

Having insight into the hydraulic performance of trays and packing can empower you to make better decisions and get the most out of new and existing columns. With the new Column Analysis feature in V9 of Aspen HYSYS and Aspen Plus, interactive visualization and new and updated correlations can enable you to understand the behavior of the column and its effect on the full process.

With new insight into the hydraulic performance of trays and packing you can make better decisions for more efficient column design, operation support and troubleshooting. This white paper compares the results of the new functionality to KG-TOWER and Sulcol software, as well as experimental data. 

Dehydration units are often overdesigned, resulting in high capital or operating costs. In order to ensure design options meet the necessary requirements of saving capital, solvent or energy costs, thermodynamic modeling and a holistic view of operations is needed. This paper discusses the dehydration modeling technology available with Aspen HYSYS in V10 and above. Aspen HYSYS has historically employed the glycol property package for TEG. With the addition of the Cubic-Plus-Association (CPA) package in V10, Aspen HYSYS can be used to model dehydration with TEG, MEG and DEG.

Learn how Process Ecology, a Calgary-based oil and gas consultancy that assists gas processing plants in the operation of their facilities, used Aspen HYSYS to model and provide operating strategies to minimize air emissions, optimize use of solvents and eliminate permit violations.

With the new Plant Data feature, you can save time by connecting to plant data and calibrating directly within the Aspen HYSYS or Aspen Plus environment. Create a digital twin of your plant.

This valuable resource provides additional insights from our technical experts on how users can use historical plant data to maximize model accuracy.

The increasing pressure to reduce plant operating costs and maximize profitability can cause anxiety for any plant manager or process engineer. During this one-hour webinar, learn how SABIC took a collaborative approach to solving complex plant issues by using process models to support plant manufacturing and operations teams. By utilizing Aspen Plus® with Aspen Simulation Workbook (ASW), they enabled plant engineers and operators to benefit from the knowledge and insight gained using AspenTech software.

In this white paper, plant managers, engineers and supervisors can learn the different ways simulations models can be used throughout the lifecycle of their plant. It focuses on seven areas you can use process simulation software (like Aspen Plus or Aspen HYSYS) for troubleshooting, process monitoring, and real time performance monitoring or real time optimization (RTO).
