Aveva Visual Flare Safety Relief Design 2025: Software for Flare System and Pressure Relief Analysis

Aveva Visual Flare Safety Relief Design 2025 is a specialized engineering software application used for the design, analysis, and rating of pressure relief systems and flare headers in process plants. It is an critical tool for ensuring process safety, regulatory compliance, and operational integrity in industries like oil and gas, petrochemicals, and refining.

Core Purpose: Managing Overpressure Scenarios

The software is designed to answer vital safety questions:

• Can the plant's flare header and relief systems safely handle simultaneous overpressure events from multiple equipment sources?

• Are backpressures in the flare header within acceptable limits for all relief devices?

• Is the system compliant with industry standards like API 520, API 521, and ASME?

Key Features & Capabilities

1. Integrated Flare System Modeling

• Network Modeling: Build an accurate model of the entire flare and relief header network, including pipes, valves, fittings, and other components.

• Relief Device Integration: Incorporate data for all pressure relief devices (safety valves, rupture discs, etc.) and their respective relieving scenarios.

• Multiple Source Analysis: Simulate the simultaneous discharge from multiple relief devices to identify the worst-case loading on the flare system.

2. Comprehensive Scenario & Load Analysis

• Relief Scenario Management: Define and manage a wide range of overpressure scenarios (e.g., fire, cooling water failure, control valve failure).

• Phase Behavior Modeling: Accurately model the behavior of multi-phase flows (gas, liquid, and two-phase) through the flare headers, which is critical for calculating backpressure.

• Time-Dependent (Transient) Analysis: Model dynamic relief events where flow rates and compositions change over time, providing a more realistic analysis than steady-state.

3. Critical Design Calculations & Compliance

• Backpressure Analysis: Calculate the backpressure at each relief device to ensure it does not exceed the limits specified by the valve manufacturer and API standards, which could impair the valve's operation.

• Fluid Property Calculations: Uses integrated property databases and equations of state for accurate fluid characterization during relief events.

• Mach Number & Velocity Checks: Analyze Mach numbers and fluid velocities to ensure they remain within acceptable limits to prevent sonic flow, excessive noise, and erosion.

4. Visualization & Reporting

• System Visualization: Graphically visualize the flare network, including color-coded results for pressure, temperature, and Mach number, making it easy to identify bottlenecks and problem areas.

• Comprehensive Reporting: Generate detailed, standardized reports for design verification, safety audits, and regulatory compliance.
