Process modelling of CO2 Conditioning – Liquefaction and Compression

This project aims to find a novel and energy-efficient way to process captured CO2 for transportation and storage. This project is part of the EU H2020 project DMXTM Demonstration in Dunkirk (3D).

During the last decade, CCS technologies have received increasing attention from our society as solutions to reduce CO2 emissions and mitigate global warming. Within these technologies, the CO2 capture, transportation, and storage technologies have been studied fairly well. The CO2 conditioning process however, which consumes about 4% of total power produced at power plants, has been comparatively overlooked.

 

In this project, CO2 conditioning technologies for ship and pipeline transport, including CO2 purification, compression, and liquefaction processes, are reviewed, simulated, and compared.

 

The objectives of this project are to review the current CO2 purification, compression, and liquefaction technologies and to simulate novel CO2 conditioning processes in ASPEN HYSYS. The simulation includes designs with a base case that is comparable to the literature and designs that include specific purification units that will meet the requirement for the “3D” project. In addition, economic evaluation is performed to calculate the CAPEX and OPEX of the designed conditioning process. Finally, different thermodynamics models for the CO2 conditioning processes are compared to each other.

 

This project is part of the EU H2020 project DMXTM Demonstration in Dunkirk (3D). It aims to reduce CO2 emissions from the steelmaking industry. The main objective of the 3D project is to demonstrate the efficiency of the DMXTM process, developed by IFP Energies Nouvelles (IFPEN), and to implement the first unit for CO2 capture from blast furnace gas at ArcelorMittal’s steel production site in Dunkirk.
