Flare Network Design and

Rating

Course Number: EHY2511

Duration: 2 day

CEUs Awarded: 1.4

Level: Intermediate

Course Overview

Learn the fundamental flare network

modeling techniques for pipeline design.

Learn the basics for rating a flare

convergent, divergent and looped network

for the constraint violations (Mach number,

MABP, Noise, velocity, RhoV2) & for

pressure, temperature and flow profile

throughout the network.

Understand the solver messages toanalyze the flow network problems and

review options to take corrective measures.

Review results to perform process safety

studies for pressure & temperature beyond

allowable range and erosion problems

(RhoV2) for healthiness of the flow network

in the real plant.

Review flare network simulation

computation convergence problems and

examine solver solution methods.

Customize reports using MS excel macro

Import sources from Aspen Plus / Aspen

HYSYS, Export and import data from the

MS access and MS excel
