Suitability of different twin-fluid atomizer types for CO2 capture in spray columns
Original language description
Post-combustion-capture of primary greenhouse gases is one of the global warming reduction methods. Twin-fluid atomizers can be used for spraying of aqueous ammonia solutions, which scrub CO2 from flue gasses. This process requires well-tailored spray characteristics, such as mean drop size, drop size distribution and droplet density. Spray cone angle (SCA), and droplet velocity are additionally relevant in spray mixing and droplet-gas interactions in spray columns. Choosing a relevant atomizer and optimum operation regime allow for effective solvent utilization in the flue gas scrubbing process. The present work examines four different twin-fluid atomizers operated at an inlet pressure of 0.05, 0.1 and 0.2 MPa with gas-to-liquid ratio (GLR) 2.5, 5 and 10%: classic effervescent atomizer with single exit orifice, multi-hole effervescent atomizer with four exit orifices and two novel “impinging” effervescent atomizers with impingement angles of 20° and 45°. Their spray structure and SCA were analysed us
