Evaluation of the performance, feasibility, and optimization of carbon capture technologies, particularly deep removal with thermal regeneration using amines. The focus lies on validating models for simulating thermal regeneration processes and conducting comprehensive test campaigns at RWE’s capture pilot plant to gather crucial data for model validation. Through parametric campaigns, emissions mitigation campaigns, and degradation campaigns, at this stage we aim to optimize operational parameters and minimize solvent losses, contributing to the advancement of efficient and sustainable carbon capture methods. The main focus of the in total 14 months of pilot plant testing at Niederaussem is to gain key performance data of amine-based CO₂ capture with highest capture rates from 98 to >99%.
