Hot Potassium Carbonate technology is designed to efficiently capture CO2 from industrial emissions while maximizing energy recovery. Here’s how the process works:
Stage 1: Flue Gas Cooling, Cleaning, and Compression
Initially, the flue gas is cooled, and impurities are removed to prepare it for the carbon capture process. Next, the flue gas is compressed to high pressure, reducing its volume and driving the carbon capture reaction. After compression, the flue gas is fed into the absorber.
Stage 2: CO2 Absorption
In the absorber, potassium carbonate (K₂CO₃) reacts with CO2 and water from the compressed flue gas, forming potassium bicarbonate (KHCO₃). This step captures the CO2 from the gas stream efficiently, preparing it for the regeneration process.
Stage 3: Regeneration and CO₂ Release
The solution rich in potassium bicarbonate is transferred to a desorber or stripper, where it is heated. The heat, supplied either by waste or low-quality heat from the existing industrial or power plant or via recirculated steam compressors, powers the process. Some heat is also recovered from the initial gas compression step. This stage regenerates potassium carbonate (K₂CO₃), releasing high-purity CO₂ for storage or further industrial use.
Stage 4: Recycling and Energy Recovery
Finally, the regenerated potassium carbonate is recycled back to the absorber, completing the cycle. At the same time, energy is recovered from the process, including compression and desorption steps. This energy can be repurposed for district heating or industrial applications, enhancing overall efficiency and reducing operational costs.
Energy Recovery and Power-to-Heat Conversion
HPC+ technology not only captures CO₂ but also recovers heat from the process, converting it into valuable energy. This heat can be used for industrial applications or repurposed as district heating, significantly enhancing energy efficiency and boosting the capacity of district heating networks.
