EFC Task Force: CO2-Corrosion in CCS-Applications


Mission

With the increase of awareness related to Carbon Capture (Utilization) and Storage (CCS) technology and the worldwide introduction of this technique to many fields in order to minimize carbon dioxide emission to the atmosphere, the safety of this technology is a widely discussed problem.

Regarding corrosion, CO2 and its precipitations can interact with the materials used for compression/transportation/injection of emission gasses from combustion processes. Therefore, selection of appropriate material and understanding the mechanisms are key factors in order to increase the safety and reliability of the CCS technology as a basis of its realizability.

This task force is devoted to the evaluation of the behavior of different materials in certain CO2-media considering process related circumstances and technical possibilities in Europe and worldwide. Open questions are addressed; possible solutions are elaborated and shown.

The task force aims at using the European network of experts to collect and merge the present understanding in the field of CO2-related corrosion, identify the needs for further research, both in basics and application, evaluate existing testing methods, promote new investigation methods, and foster normative work on an international basis. 

The task force addresses the following general topics:

Research

  • Identification of the most important factors influencing the corrosion system as the basis of research and development.
  • Improvement of the understanding of the reaction mechanisms and interactions of precipitations with the different materials used in gaseous, dissolved, dense phase and supercritical CO2, in cooperation with other EFC Working Parties, especially WP 13 and appropriate TEGs of NACE International.

Investigation and Testing

  • Evaluation and optimization of existing and new methods for investigation and testing of the corrosion resistance of materials.
  • Emphasis is put on the evaluation and further development of short term testing for life time prediction.

Knowledge transfer

  • Review, systematization, equalization and dissemination of the current knowledge of corrosion resistance and application limits of the respective materials.
  • Organization of workshops, seminars, and symposia with respect to basic understanding and industrial application. This shall include mechanism analysis and service strategies.
  • Active contribution to current standardization activities
    (e.g. ISO TC 265).

This task force deals with following items of major interest:

  • Test methods
  • CO2-effect concerning scaling, general and pitting corrosion
  • Interactions with typical precipitations like SOx, NOx, H2S and water
  • Qualification of carbon and stainless steels
  • Evaluation of appropriate protection measures
  • Special considerations within the different parts of an installation (separation, compression, transport and injection)
  • Problems of composition variations in practice

Last TF meeting

At EUROCORR 2017, Praha, Czech Rep., there were around 60 attendees during the whole one day workshop. Within this workshop case studies from industry, practice related and academic research work have shown the current state of knowledge and the need of further research and information exchange.

The minutes of the last business meeting (6 Sept 2017, Praha, Czech Rep.) can be found here.

Next TF meeting

At EUROCORR 2018, Kraków, Poland
