The goal of the Dalmatien project is to have an exhaustive list of the degradation products of MEA and piperazine (PZ), to understand their formation and to know their toxicity.

To reach this objective, the following actions have to be achieved:

  1. Develop the experimental protocols for amine degradation (Task 1).
  2. Develop the sampling and analysis methods (Task 2).
  3. Validate the experimental protocol (Task 3) by cross-comparing the analysis results (Task 2) obtained by the various partners.
  4. Study the amine degradation (Task 1) and provide the list of the degradation products (Task 1) by analysis of the gas effluents and of the amine solution (Task 2).
  5. Propose the reaction mechanisms of degradation products formation (Task 1). In particular, study the interactions between the amine and the various metallic materials that can be used for CO2 capture.
  6. Study the toxicology (Task 4) of the degradation products and carry out a first health risk analysis so as to highlight the critical products (Task 4).

The scientific programme of the project is thus structured around 4 complementary tasks outlined in sub-tasks:


  • Task 1: study of the degradation of amines MEA and PZ
    • Sub-task 1.1: development of the laboratory experimental protocols representative of industrial conditions
    • Sub-task 1.2: study of the amine degradation and of the degradation product formation mechanisms


  • Task 2: analysis of the degradation products formed in Tasks 1 and 3
    • Sub-task 2.1: bibliographic review and IFPEN and EDF knowledge
    • Sub-task 2.2: development of the sampling methods and of the gas and liquid phase analysis methods
    • Sub-task 2.3: analysis of the samples of the various partners.


  • Task 3: validation of the methodology developed in Task 1


  • Task 4: toxicological studies of the degradation products obtained in Tasks 1 and 3, and analyzed in Task 2.


This project is thus structured around 3 main fields:

  • CO2 capture
  • analysis
  • toxicology and associated risk analysis.


Particular skills are required in different and complementary fields:

  • industrial knowledge of the fumes to be treated and of the development of CO2 capture
  • laboratory experimentation control
  • amines chemistry
  • gas and liquid sampling, sample processing
  • development of dedicated analysis methods
  • toxicology
  • methods of calculating missing toxicological data.


Furthermore, the goal of the Dalmatien project is to share with the scientific community the knowledge acquired throughout the project. Dissemination thus is an important aspect of this project. The partners are asked to pass on the results obtained throughout the project through publications or congresses for example.


The contributions of this project to the scientific community are numerous:

  • comprehension of degradation mechanisms
  • influence of the metallic materials on the nature of the degradation products formed and their concentration
  • exhaustive list of the degradation products in the case of MEA and PZ
  • gas and liquid phase sampling and analysis methods
  • toxicological data
  • toxicological data calculation methods.

The methods developed within the scope of this project and thus shared can therefore be adopted by the various players in the field of post-combustion CO2 capture and applied to the study of other amine formulations.
