Aspen Hysys Dynamics Uses
Hysys Dynamic Enables user to move from steady state to transient mode to provide solution issue
related to transient mode,
✓ Hysys dynamic can be used for failure analysis or stress disturbances/ Event and Cause &
Effect for a real plant can be modeled. Providing the facility for Off-line comparison instead
of disturbing the actual process.
✓ Develop Complete process control schemes through which the user can improve the
production, quality, product loss reduction before implantation in real plant.
✓ Use Hysys dynamic simulator for design, engineering verification, DCS checkout,
OTS(operator training simulator) deployment.
✓ Enable user to make policies for startup, shutdown and other transition scheme.
✓ Valves Operating Characteristics can be modeled with issue like leaky valves and Actuator
stickiness time constant.
✓ In separators Nozzle location can impact the phase and composition of a product. Hysys
dynamics can be used to resolve or detect undesired operating conditions or modifying the
nozzle positions.
✓ Hysys Dynamics can predict the heat losses for a vessel due to conduction, convection that
account of insulation with respect to external environment.
✓ Hysys dynamic can be used for modeling Vessel Depressurization for Fire and other
emergency scenarios Cases.
✓ In Hysys dynamics user can model develop pressure profile based on the tray geometry
which is not possible is steady state. Enabling user to get real plant behavior.
✓ Ensuring real PSV’s and safety devices modeling to protect column from an overpressure
scenario.
✓ Activated Dynamic compressor surge analysis and surge control can be performed ensuring
the safety, ensuring the life of equipment and increasing the efficiency of the compressor.
✓ By using the Pipeline Hydraulics, the prediction of pipeline pressure drops and
troubleshooting of operational problems of multiphase fluids can be solved.
Aspen Flare Analyzer
✓ Used for sizing, rating and debottlenecking of Flare systems. Models flare networks,
covering from the sources (PSV, FCV, PV) to the flare tip.
✓ Flare Analyzer can implement different emergency scenario with are available as
predefined and also user can define.
✓ Aspen Flare Analyzer do help to achieve the OSHA standards ensuring frame work for
employees to prevent serious accidents.
✓ Dynamic Relief Load or Flare Mode is an option available in the Hysys dynamics. As the
Flare analyzer is a steady state software the user can combine use the Hysys Dynamic
and Flare Analyzer to see the transient flow effect on the system and flare network.
✓ Aspen Flare Analyzer help to ensure the safe limit of Noise, Acoustic Vibration Analysis,
ρv2 (Vibration Analysis), Velocity and Mach No., Also hep to increase the life of the
network.
✓ In Aspen Flare Analyzer Radiation Analysis can be performed a key indicator for sizing
and performance of Flare System. Also, it can help in Documentation for Industrial
Audits
