Plant Management
Plant simulation is a critical part of any plant management
strategy today and process companies are turning to the most sophisticated solutions on the market. Sean Ottewell reports.
Simulation targets compressors, consumption and emissions
U
sing dynamic modelling and simulation, Aspen Technology’s version 8.6 of its aspenONE software addresses
a number of significant issues for process industries.
Among new features included in v8.6 is Activated Dynamics Analysis, which allows dynamic modelling of compressors. V8.6 of Aspen HYSYS software automates dynamic modelling with a single button click to speed up model setup and enable more process engineers to perform compressor operability screening. Companies operating compressors, especially those processing gas in upstream and midstream, will benefit from better flow assurance and reduced maintenance cost.
The new version includes expanded pressure safety valve
design and rating in Aspen Plus and Aspen HYSYS. In v8.6 new fire analysis scenario calculations – accounting for latent heat and temperature change – and rupture disk sizing have been added. All functionality is available in both Aspen Plus and Aspen HYSYS, improving chemical and energy operators’ compliance with API 520 and 521.
Furthermore, new detailed unit rate estimating in Aspen Capital Cost Estimator (ACCE) extends the software’s scope into the detailed estimating phase of a project. ACCE v8.6 enables easy adjustment of labour and material unit rates as well as materials of construction. The result is expected to enable organisations to achieve up to 10% accuracy or better, reducing project risk and improving decision making around the use of capital.
