Course Id: EHY2511 | Duration: 2.00 day(s) | Level: Intermediate

Course Objective

In a plant emergency, process material must safely relieve through the flare system for disposal. An important step in process design and plant revamp is to ensure that the flare network can handle the flowrates and meet design constraints on backpressure, Mach number, noise, and pipe fatigue. Aspen Flare System Analyzer has the capability to solve complex network hydraulics and incorporate industry standards. Simultaneously execute multiple emergency scenarios, identify potential process bottlenecks, and validate the capacity of the flare network. This technology can help reduce capital cost by determining optimum equipment sizes, and, more importantly, assure the safety of the plant.

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 to analyze 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.
• Discuss customize reports using MS excel macro
• Import sources from Aspen HYSYS®, Export and import data from the MS access and MS excel
