Heat integrated stripper for amine-based CO2 capture: Pilot and simulation study with AMP/Pz solvent.

The effective management of CO2 emissions is crucial for industrial decarbonisation and environmental sustainability. Chemical absorption remains a key technology for CO2 capture, but improving its efficiency is essential to reduce energy consumption and operational costs. This study explores the application of a Heat Integrated Stripper (HIS) as an advanced pollution control method, enhancing the sustainability of amine-based CO2 capture using an AMP/Pz (30/10 %) solvent. Pilot-scale tests, conducted at a power plant with a flue gas flow rate of 200 m3/h, demonstrated a 6 % reduction in reboiler heat duty (to 3.26 MJ/kgCO2) and a 24 % decrease in cross-flow heat exchanger load, leading to lower cooling water demand and improved resource efficiency. Simulations indicate further potential for energy savings and emissions reduction through enhanced thermal integration. The lower top temperature in the stripper mitigates amine carryover and corrosion risks, improving long-term system reliability and reducing environmental impact. HIS presents a scalable strategy for industrial CO2 capture, supporting the implementation of cleaner production practices and climate change mitigation efforts. The findings provide critical data for scaling up HIS technology in real industrial environments, offering a pathway to enhance resource optimization, sustainability, and the economic viability of CCS processes across multiple sectors.
