Degradation - Corrosion & Corrosion Prevention

5 days MCO/CICP-E
Level
Proficiency
Audience
  • Experienced engineers, managers and technical staff involved in the technical aspects of refineries, chemical and petrochemical plants.
Purpose
  • To deepen knowledge and management of pressure equipment degradations and corrosion.
Learning Objectives
  • To study steels and alloys equipment degradations in the oil, gas and chemical industries.
  • To describe protective measures against such corrosion.
  • To explain the appropriate control and assessment of degradation and corrosion of pressure equipment.
Ways and means
  • Active teaching methods are used to promote a pooling of experience.
  • Use of pictures and samples to develop practical case studies.
  • Theoretical knowledge is assimilated and put into practice through case studies with the collaboration of specialists from the industry.

Definition and mechanisms of corrosion 1 day
  • Ferrous and non-ferrous metals: structure, composition, mechanical properties.
  • Definitions: wet corrosion, dry corrosion.
  • Cost of corrosion: financial and human.
  • Basics: electrochemical mechanisms, polarization, passivity, diffusion.
Usual types of degradations 1 day
  • Analysis of the origin and development of each form of corrosion, possible prevention strategies.
  • Forms of corrosion studied: uniform, galvanic, pitting, crevice, intergranular, selective, corrosion-erosion and cavitation, stress corrosion, contact corrosion.
Types of corrosion in the chemical and oil & gas industries 1.5 days
  • Each type of corrosion is studied together with possible remedial treatment.
  • Particular forms of corrosion encountered in industrial installations:
  • Hydrogen and hydrogen sulfide, stack gas corrosion, naphthenic acid corrosion, corrosion in a topping unit, polythionic acid corrosion, caustic soda corrosion, corrosion in an aqueous environment, atmospheric corrosion, seawater corrosion or corrosion by oxidation at high temperatures, or liquid ammonia, corrosion of reinforced concrete.
  • Corrosion specific to the chemical industry: corrosion by mineral acids, bases, nitrates, ammonia or chlorine.
  • Case studies of corrosion observed in process industry units: identification of the form of corrosion and suggested remedial treatment.
Corrosion prevention and monitoring 1.5 days
  • Design of equipment to avoid corrosion.
  • Material selection.
  • Corrosion inhibitors, filming, passivating, neutralizing, oxygen absorbers.
  • Anti-corrosion coatings and systems.
  • Cathodic protection with sacrificial anodes or imposed current.
  • Methodology and control of processes. Control of process and environmental parameters.
  • Case studies on prevention strategies implemented in process units.
  • Corrosion coupons and probes.
  • Non-destructive testing.
  • Corrosion monitoring plan.
Corrosion monitoring 0.5 day
  • Corrosion coupons and probes.
