Build a flowsheet with a control valve and a relief valve. Connect via tail pipe, tee, and header to flare stack; define two scenarios with delta v and diameter data.
Open Aspen Flare System Analyzer v14, create a project with user and job code, add hydrocarbon components methane, ethane, propane, and set metric units in preferences for the flare system.
Model a flare system with a stack and flare tip, define upstream and downstream, and note unreacted components burn at the flare tip to CO2 and H2O.
Explore connectors and headers in flare network design, linking pipelines with 90 and 180 degree connectors, and identify upstream and downstream for a header to stack flare systems.
See how a T fitting splits flow into outlets, introduces 90-degree bends and pressure drops, and apply the Miller fitting loss method in an Aspen flare system analyzer workflow.
Define tail pipe as the pipe after the relief valve, distinct from pipes after other valves, with delta P based on design or rated flow, not the actual flow.
Add the first control valve named source one at tailpipe one with a 10,000 kg per hour flow constraint, and add a relief valve as source two.
Create a default scenario for each vault in Aspen Flare, set mach number to indicate compressibility, and enforce 100 decibel noise limit while cloning for source one and source two.
Define and compare network scenarios by selecting valve sources. Set calculation and heat transfer options, then review pressure, flow, and physical properties to rate the network.
Check the model before running to catch errors and heat transfer warnings, then uncheck enable heat transfer in calculation settings and set pipe length, elevation, and nominal diameter.
Create Aspen Flare network in workshop 2 by selecting components (nitrogen, carbon dioxide, methane, ethane, propane, butane, water) and configuring valves, pipes, a knockout drum, headers, and a flare stack.
Link control, safety, and relief valves with pipes, tees, connectors, and knockout drum into a pipeline network using Ctrl to connect blue and red dots from main header to flare tip.
Learn to label and rename pipelines and nodes in a flare system using a consistent naming scheme, including pipes, t connectors, valves, and flare components, with slash-based identifiers.
Specify flare system inputs by configuring pipes, flare stack, knockout drum, and tailpipes, entering diameters, lengths, elevations, and lens to support accurate calculations.
Learn how the length multiplier accounts for pressure drop from fittings in flare system simulations, applying 1.5 to pipe lengths in the editor for all pipes.
Compare fire and blocked outlet scenarios in flare network design, using pressure safety valves for fire relief and pressure control valves for blocked flow.
Add source data for the fire scenario by configuring pressure safety valves with set pressures, inlet and outlet temperatures, mass flow, rated flow, and valve type.
Set up the source data for the blocked outlet scenario with two control files, configure two pressure control valves, and run the Aspen flare system calculations.
Run the design mode calculation to compare fire and blocked scenarios, configure settings (temperature, pressure, rated flow, choke flow), and review pressure, flow, and noise results.
