component to the model predictive control scheme to better predict and account for impurities; and updating the procedure for using laboratory data within the calculations.
Managing heat supply The changes made at the plant have also reduced the site heat load, which prompted MOL to look at how best the heat supply can be managed for the whole site. Emerson is supporting this project with a study to evaluate the heat balance across the site, as well as the heat loads on the furnace. Emerson’s support will include designing and implementing the recommended modifications. “Our relationship with Emerson has been very
successful in improving the performance of our Algyõ gas plant,” continued Oláh. “Emerson’s outstanding support and extensive industry experience has established them as trusted partners, and we will continue to use their local and global resources whenever the need arises.”
More functionality Aspen Technology has released V8.3 of its aspenONE software. The release includes new functionality in Aspen HYSYS software – Acid Gas Cleaning to model gas sweetening units, and Pressure Safety Valve Sizing integrated from the acquisition of PSVPlus, which allows process engineers to size pressure safety valves as an integral part of the overall process design for the first time.
Both Acid Gas Cleaning and Pressure Safety Valve
Sizing are included in Aspen HYSYS in a single modelling environment with intuitive workflows. These new capabilities enable users to optimise processes faster and to produce inherently safer designs. Commenting on the new release, Paolo Cari, a
process engineer with Saipem, said, “The new Acid Gas Cleaning is a major step forward for gas process modelling and optimisation. “ It will help us accelerate our projects by setting up
he acid gas treatment model as an integral part of a gas process in HYSYS. “Using it with the Activated Economics and
Activated Energy features in HYSYS, we can also easily optimise our entire gas plant to further reduce our capital and energy costs.” Mehul Gandhi, senior process engineer with
Petrofac, added, “The new safety analysis is great for the relief analysis of the process unit. We can now quickly estimate relieving fluid properties and conditions, size the relief valves and produce required documentation – all without leaving HYSYS. This will minimise errors, improve the quality and speed up our work significantly.” n
