Emergency Relief System Analysis and Design

TRI*HEADER™ designs and rates converging tree piping networks, including flare headers and gathering systems. It utilizes a built-in component database to perform rigorous VLE, heat transfer, and two-phase compressible flow calculations to accurately predict fluid behavior in the network. It takes into account such phenomena as liquid holdup, choked flow, and Joule-Thompson thermal effects. In design mode, TRI*HEADER optimizes the network, solving for the minimum pipe sizes necessary to meet the flow requirements. In rating mode, TRI*HEADER™ calculates the temperature and pressure distribution throughout the network and produces a detailed summary of the flow characteristics along the pipe network. In either mode, it can design pressure relief valves per API 520 specifications, separate liquid condensate from a pipeline headed toward the flare stack, and do rigorous parallel piping segment calculations for those instances where the addition of a pipe in parallel to an existing network segment is a better solution to solving a flow bottleneck than totally replacing the pipe segment.

TRI*HEADER™ PROVIDES

Precise network flow analysis for pure components or mixtures in either liquid, vapor, or two-phase states

Optimized design mode which selects proper network pipe sizes based on user specified limitations for maximum allowed velocity, percent of critical flow, and/or pressure drop

Automatic adjustment for near sonic flow velocities

Multiple option analysis mode to handle fluid choking and locate system bottlenecks

Mix and match analysis and design modes on a single network, allowing design and What-If scenarios with additions to existing networks

Intuitive "from node" - "to node" network segment specification strategy, simplifying both input and output as well as providing for efficient calculation algorithms

Large insulation and piping material databases provided to simplify the data entry process

DIN and ANSI standard pipe sizes as well as user specified custom pipe sizes supported in both data entry and calculations

Automatic computation of both thermodynamic and transport properties of fluids using data from either an extensive built-in database or from customer specifications

Large selection of user specified equations of state for modeling thermodynamic properties of components and mixtures.

Input and output unit choices selectable from either standard or client configurable unit sets

Rigorous heat transfer calculations from the piping network to a choice of environments including buried beneath the surface, submerged in water, or suspended in air

Optional segregation of water in hydrocarbon mixtures, using built-in steam tables rather than hydrocarbon based equations of state.
