Pioneering GRP Use in Amine-Based CO2 Capture: Insights from Pilot Plant Exposure Studies

Abstract Carbon capture, sequestration, and storage (CCS) is crucial for mitigating global warming by reducing industrial CO2 emissions. To enhance the commercial viability of CCS, this study focuses on reducing capital (CAPEX) and operational (OPEX) expenditures by evaluating the use of glass reinforced plastic (GRP) in amine-based CO2 capture technologies. Previous studies on chemical compatibility (C2023-18832) and mechanical feasibility (C2024-20710) were presented at the 2023/2024 AMPP conference. This investigation involved exposing GRP materials to solvent blends in a carbon capture pilot plant over seven months. The conditions included both rich and lean amines, with temperatures ranging from 30 to 143°C. Analysis of the exposed samples indicated that GRP is technically suitable for cold amine applications (30 to 63°C). However, for hot amine application, previous lab studies indicated suitability up to 100°C though no exposure data is available from the pilot plant study in that temperature range. These findings align with prior laboratory results, affirming the suitability of GRP for cold amine applications and highlighting the risks associated with high-temperature exposures. This research supports the development of more cost-effective and durable CCS systems by identifying materials that balance performance and economic feasibility.
