Industrial gas flares

Eiffage Métal designs, from the composition and flow of the gases, any system of torches (guyed torch, torch on derrick, stable auto torch, thermal oxidizers – with their equipment – flame detection, thermocouples, ignition station, torch nose, automation, etc.).

• From gas composition and flow: analysis, combustion, sizing, radiation, releases, noise
• Schematization: PID, functional analysis and Grafcet.
• Design office: stability calculations, realization of the overall plans and modeling of the torch.

The torch systems are manufactured in our Cuincy workshops, following procedures set up by a welding engineer (welding books, QMOS, DMOS, etc.) and defined control means (radiography, penetrant, PMI). Particular attention is paid to the choice of materials:

• Carbon steel (P265GH, API5L)
• Stainless steel (310S, 304L, 316L)
• Corten steel (marine environment)

Our teams of experts carry out the assembly work of the equipment.

• Blank assembly in our workshop in Cuincy.
• Assembly on site: transport, handling, connections, piping, electricity and automation.
• Commissioning: adjustments related to installations (fluids, electricity and automation) and training of staff on site.

We carry out strict inspections of the facilities to repair or replace one or more elements of the torch. This work is carried out during unit shutdowns.

Expertise: during scheduled shutdowns, we control the entire torch system (flame detection, ignition station and pilot, summer, guying systems, verticality, etc.) in order to establish a provisional report of the work to be carried out. It is also possible to conduct this expertise using a drone (our teams are trained to fly) if the torch must remain in operation.
Revamping: restoration and modification of torch systems in our workshop in Cuincy (checks, repairs, change of spare parts, reconditioning...).
