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
this objective, the following actions have to be achieved:
- Develop the experimental
protocols for amine degradation (Task 1).
- Develop the sampling and
analysis methods (Task 2).
- Validate the experimental
protocol (Task 3) by cross-comparing the analysis results (Task 2)
obtained by the various partners.
- 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).
- 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.
- 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).
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
- 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.
project is thus structured around 3 main fields:
- CO2 capture
- toxicology and associated risk
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
- amines chemistry
- gas and liquid sampling, sample
- development of dedicated
- methods of calculating missing
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.
contributions of this project to the scientific community are numerous:
- comprehension of degradation
- 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
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.
