Abstract
The base case capture cost was estimated at EUR 114–133/tCO2, which is higher than typical costs for amine absorption. The high costs are largely due to the high liquid flow rates required for efficient mass transfer and the need to maintain low solution concentrations to prevent salt precipitation. A notable advantage of the process is its low-temperature regeneration (∼65 °C), which enables the use of waste heat. When waste heat is available at no cost, capture costs could be reduced by EUR 30–40/tCO2. The use of a heat pump was found to be economically favorable when heat costs exceed EUR 13–20/MWh, depending on electricity prices. Increasing absorption pressure and temperature were found to be promising means for improving the process performance.
