Abstract The population rise and economic development lead to increased energy utilization. This energy utilization is largely based on fossil fuel combustion and the industrial operations in oil and gas industry that result in CO emissions. The solvent mixtures of piperazine/diethanolamine (PZ/DEA) were examined to substitute for improved carbon dioxide (CO ) absorption from the natural gas 2 a b c a a b d e f c g hi Share Cite 2 2 2 2 2 CO2 solubility and thermophysical properties in aqueous mixtures of pi... https://www.sciencedirect.com/science/article/abs/pii/S2213138822005641 1 of 8 22/01/2025, 2:47 pm
