Development of a coupled process for CO2 separation and carbonation for small and medium-sized point sources (HYDRANAT)
Production companies in particular often have few options for reducing CO process-specific reasons, manufacturing companies in particular often have few options for reducing CO2 emissions through process changes. Due to their high energy requirements or unsatisfactory satisfactory separation performance, the processes available to date for CO processes for CO2 separation have not achieved any real market penetration. achieve real market penetration. At this point, the present research project presents presents an innovative approach to solving this problem by using the much more efficient process for carbon dioxide capture using gas hydrates with the long-term stable long-term stable mineralization of the CO2 in carbonates and and transferring it to an industrial, continuous scale for small and medium-sized emitters. emitters.
The prototype designed in this way will be tested in the final year of the project in an industrial environment with a partial flow of real exhaust gases. Finally, the process will be scaled up to an order of magnitude of 1000 m3/h its optimal thermal integration into the main process will be designed and its economic efficiency will be designed and the economic efficiency will be considered.
Background and motivation
The decarbonization of the economy is considered to be one of the greatest socio-economic challenge of our time. The current IPCC report names BECCS (BioEnergy Carbon Capture and Storage) and CCUS (Carbon Capture and building blocks are BECCS (BioEnergy Carbon Capture and Storage) and CCUS (Carbon Capture, Utilization and Storage) from industrial processes. Especially manufacturing companies in particular often have few options for reducing CO few options for reducing CO2 emissions through process changes. process changes. Due to their high energy requirements or unsatisfactory satisfactory separation performance, the processes available to date for CO processes for CO2 separation have not achieved any real market penetration. achieve real market penetration. At this point, the present research project presents presents an innovative solution.
Objectives
The project is highly relevant to society, by contributing to the reduction of climate emissions, especially for production processes that are contribution to the reduction of climate emissions. In addition, there is a high economic relevance with exploitation potential.
Procedure and methodology
At the heart of the process are reactors optimized in terms of reaction, heat and fluid mechanics. optimized reactors are designed. The remaining plant components are then plant components for a continuous process with the order of magnitude of 10 - 50 m³ of flue gas per hour will be designed and installed. At the same time, the existing appendices of the company partners will be analyzed for efficiency improvements and potentials for the primary reduction of CO2 emissions are to be implemented.
A parameter study of the prototype plant with synthetic and real flue gases is to flue gases is intended to evaluate the performance of the concept and identify optimization potential. The prototype designed in this way will be in an industrial environment with a partial flow of the real exhaust gases. exhaust gases.
Finally a scale-up of the process to an order of magnitude of 1000 m3/h its optimal thermal integration into the main process will be designed and the and the economic efficiency will be considered. A life cycle assessment of the minerals and residual materials used rounds off the topic.
The work packages are structured as follows:
- AP1: Reaction engineering hydrates and carbonates
- AP2: Investigation feedstock logistics
- AP3: Design of the prototype plant
- AP4: Prototype tests (both WissMA)
- AP5: Real-world tests with cooperation partners (both WissMA)
- AP6: Scale-up & analysis of utilization and marketability
