Foam and Antifoam Behavior of PDMS in MDEA-PZ Solution in the Presence of Different Degradation Products for CO2 Absorption Process

Absorption is one of the most established techniques to capture CO2 from natural gas and post-combustion processes. Nevertheless, absorption process frequently suffers various operational issues, including foaming. The main objective current work elucidate effect degradation product on foaming behavior in methyldiethanolamine (MDEA) piperazine (PZ) solution evaluate antifoaming performance polydimethylsiloxane (PDMS) antifoam. was investigated based types product, temperature, flow rate. presence glycine, heptanoic acid, hexadecane, bicine MDEA-PZ cause significant hexadecane produced highest amount foam, followed by glycine lastly bicine. It found that increasing rate increases tendency foam stability. Furthermore, temperature tendency, but reduces Moreover, PDMS antifoam able reduce formation different products at temperatures rates. works best with average height reduction 19%. Hence, this will demonstrate importance reducing its effect.
