Size and rate pressure safety valves as per industry standards.
Ensure that proper relief valve sizing methods are used throughout the overpressure analysis. Accepted industry standard API RP 520, 521 is implemented in Aspen HYSYS to calculate necessary safety valve sizing specifications, including relief loads and orifice sizes.
Automatically import PSV sizes and scenarios information to analyze flare network.
Information generated by Aspen HYSYS during PSV analysis can easily and automatically be imported within Aspen Flare System Analyzer to map relief valve and flare scenarios. Compile all overpressure contingencies by type or name from various PSVs in a plant to create detailed and rigorous flare network solutions.
Use process data to analyze multiple overpressure protection scenarios.
For each pressure safety valve, 25 overpressure relief situations are available for evaluation. Data from a completed Aspen HYSYS simulation – including dynamic safety studies – can be directly leveraged to aid in the design of PSVs for both single and mixed phase systems, including the obtainment of relief loads and orifice sizing. Additionally, relief load calculations for tedious overpressure scenarios (such as fire, control valve failure, and exchanger tube rupture) are built in to HYSYS to simplify workflow.
Breeze through highly rigorous PSV sizing methods.
Aspen HYSYS generates all required fluid properties for relief loads, enabling process engineers to ultimately analyze more scenarios. Aspen HYSYS handles calculation and integration methods that would be impossible to complete by hand. Sizing methods for critical or subcritical vapor, steam, liquid and all mixed phase methods detailed by API 520, 521 are just a click away.
Automatically generate required valve documentation.
The documentation builder tool pulls process and valve sizing results from Aspen HYSYS to create data and summary sheets that can be used within a company or submitted to safety regulatory agencies and valve vendors. Using the documentation builder maintains information about the PSV study in one central location, eliminates the need to manually complete reports, and cuts the time required to finalize valve design.

Size pipe lines leading to and from the relief valves.
The line sizing function in Aspen HYSYS allows the user to size the inlet and outlet pipes to the relieving device according to user defined pressure drop and velocity constraints in the fluid flow. Line equivalent length can also be calculated by specifying the type and quantity of piping components present. These sizing methods are available for single and mixed phase systems.
