Advantages over traditional solvents Piperazine-based CO₂ solvents have emerged as a promising solution for carbon capture due to their significant advantages over traditional absorbents. These solvents exhibit high CO₂ absorption capacity, rapid reaction kinetics, and excellent thermal stability. For instance, piperazine (PZ) is known for its low vapor pressure, low degradation rate, and minimal corrosivity, making it highly suitable for industrial applications. Additionally, PZ-based solvents require less regeneration energy compared to conventional amines like monoethanolamine (MEA), resulting in lower operational costs.

Applications The applications of piperazine-based CO₂ solvents span multiple industries, including coal-fired and natural gas power plants, chemical off-gas treatment, and process gas from steel and cement industries.

In power plants, these solvents can efficiently capture CO₂ from flue gases, even in the presence of contaminants like sulfur dioxide (SO₂), which is often found in industrial emissions. For example, studies have shown that PZ-based solvents can maintain high CO₂ absorption efficiency and stability when exposed to SO₂, making them suitable for retrofitting existing power plants.

In the steel and cement industries, where high-temperature process gases are common, piperazine-based solvents demonstrate superior performance due to their thermal stability and ability to handle high CO₂ concentrations. Moreover, these solvents can be blended with other compounds, such as amino acids or potassium carbonate, to further enhance their absorption capacity and reduce energy consumption. For instance, mixtures of piperazine and potassium carbonate have shown significant improvements in CO₂ capture efficiency compared to traditional MEA solutions.

Tsinghua University & Xinova Environment
