Enhancing CO۲ Absorption in Venturi Scrubber with Nanofluids

This study investigates the efficiency of CO۲ 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 CO۲ absorption using water/iron oxide nanoplates. Key findings reveal that a nano-iron oxide/water nanofluid (۲۵%) combined with graphene nanoplates (۷۵%) at a ۰.۵% 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 ۱ to ۲ L/min but decreases beyond that. Conversely, constant magnetic fields reduce efficiency, with notable decreases at higher field strengths. Optimal CO۲ absorption efficiency of ۹۴.۵% is achieved at an airflow rate of ۴.۸ m³/min and a solvent flow rate of ۲ L/min without a magnetic field. Alternating magnetic fields enhance efficiency, achieving up to ۹۹.۸% under specific conditions. The study underscores the importance of balancing airflow and solvent flow rates for maximizing CO۲ absorption efficiency in venturi devices.
