Tubular Furnaces

  • Project or process control engineers in refineries or petrochemical plants, involved in furnace design and performance follow-up.
  • To provide in-depth knowledge of critical design rules for tubular furnaces used in the petroleum and petrochemicals industries.
Learning Objectives
  • To list the main industrial issues of furnace technology, operating conditions and constraints.
  • To structure process data and define key criteria for furnace design.
  • To identify pollution sources and ways to reduce emissions.
Ways and means
  • Course delivered by IFP Training experts and furnace design engineers from Heurtey Petrochem SA.
  • Case study used throughout the course to design the main characteristics of radiant and convection zones.
