Description

Separation and gas cleaning technologies, based on liquid sorbents, rely on efficient mass transfer in gas-liquid contactors. Liquid atomization is frequent method of interfacial area increasing. Several atomizer types (pressure-swirl and twin-fluid, multi-nozzle, or flat-jet arrays) were proposed and installed in spray columns (SC) particularly for CO2 capture with absorption using alkanolamine solutions and aqueous ammonia. Several strategies (from the above listed) are studied for uniform film/droplets production and mass transfer enhancement between gas and liquid phases. The main target is to evaluate suitability of these film and spray systems for gas absorption purposes. Selection of the most competitive atomization technique, reduction of the spray polydispersisty (film stability) and its further development in line with modification of liquid rheology. Enhancement of the turbulent mixing via external force (ultrasonic irradiation induction, vortex flow in SC) are additional applied strategies. Effect of above aspects on CO2 capture efficiency in SC will be studied.
