عنوان انگلیسی Enhancing CO2 Absorption in Venturi Scrubber with Nanofluids
چکیده انگلیسی مقاله This study investigates the efficiency of CO2 elimination from airflow using a venturi washing device, focusing on the role of tetramethylammonium hydroxide and magnetic fields in enhancing nanofluid performance. The research examines various parameters, including intake airflow, solvent flow rate, magnetic field type and strength, and CO2 absorption using water/iron oxide nanoplates. Key findings reveal that a nano-iron oxide/water nanofluid (25%) combined with graphene nanoplates (75%) at a 0.5% mass concentration in the presence of tetramethylammonium hydroxide optimizes performance. Absorption efficiency initially peaks with increased inlet airflow but declines with further increases. In the absence of a magnetic field, efficiency rises with a solvent flow rate increase from 1 to 2 L/min but decreases beyond that. Conversely, constant magnetic fields reduce efficiency, with notable decreases at higher field strengths. Optimal CO2 absorption efficiency of 94.5% is achieved at an airflow rate of 4.8 m³/min and a solvent flow rate of 2 L/min without a magnetic field. Alternating magnetic fields enhance efficiency, achieving up to 99.8% under specific conditions. The study underscores the importance of balancing airflow and solvent flow rates for maximizing CO2 absorption efficiency in venturi devices.
