SO2 removal by seawater in a spray tower: Experimental study and mathematical modeling

Abstract: In this article, the reactive absorption of SO 2 by seawater is studied in a spray tower experimentally and mathematically. The liquid film formation on the tower wall is implemented in the model and measured experimentally at different operating conditions. The effect of liquid to gas flow rate, initial SO 2 concentration in gas phase and initial gas temperature on SO 2 removal efficiency is examined. Regarding the importance of liquid droplets hydrodynamics and its effect on the performance of the equipment, the required differential equations for predicting the trajectory and local velocity of droplets are also developed based on the nozzle and spray characteristics and solved simultaneously with other governing equations. In order to survey the effect of nozzle type on removal efficiency, two different types of nozzles are examined. Semi-empirical correlations are proposed for two different nozzles by using experimental data and droplets hydrodynamics model, to predict the amount and the variation of liquid film mass flow rate on the spray tower wall. Results indicate that neglecting the liquid film formation leads to an average of 23% error in predicting the removal efficiency when nozzle type 1 is used, while the calculated error of model by considering the film formation is reduced to 4%. By implementation of droplets hydrodynamics model and applying a modified thermodynamics model for predicting the behavior of the existing chemical reactions, the capability of the spray tower model in predicting the SO 2 removal efficiency is enhanced.

Mass Transfer and Liquid‐Film Formation in a Spray Tower for SO2 Removal in Sodium Hydroxide Solution

Abstract: Spray towers allow for controlling air pollution in which a liquid is sprayed in small droplets to produce a large interfacial area for mass transfer between a gas and a liquid phase. An experimental study of a spray tower for removing SO2 is described. The experiments were carried out under different operating conditions by varying the gas velocity, liquid flow rate, and SO2 concentration. SO2 removal efficiency, volumetric mass transfer coefficient, and liquid-film formation as a result of the collision of droplets against the tower wall are investigated. Removal efficiency and volumetric mass transfer coefficient are analyzed as a function of gas velocity, liquid flow rate, and SO2 concentration, while liquid-film formation is evaluated as a function of tower height. The results indicate high removal efficiency. Correlations to predict the volumetric mass transfer coefficient are also proposed.

Numerical simulation of NO2 absorption using sodium sulfite in a spray tower

Abstract: BACKGROUND Wet flue gas desulfurization combined with ozone is a promising technology which could remove NOx effectively. However, there are few reports focusing on simulations of the absorption process of NO2 in a spray tower. A computational fluid dynamics model including chemical absorption was developed to simulate the absorption process of NO2. Simulations of different cases were executed to explore the influences of operating conditions. RESULTS The errors between predicted and experimental values were less than 5% under different operating conditions and the model had depicted the tendency very well. For instance, an increase in L/G from 11 to 16 resulted in the growth of η from 90.9% to 96.3%. When the solution concentration raised from 0.025 mol L−1 to 0.0875 mol L−1 could result in an increase of η from 89.1% to 98.6%. CONCLUSION The model developed in the present work was effective in determining the operating parameters of the spray tower for NO2 absorption, which could be utilized for the design and optimization of industrial apparatus. Moreover, the model can also evaluate the best positions of the spraying nozzles, the distance between the spray levels and other parameters for industrial application. © 2015 Society of Chemical Industry

Modeling and experimental studies of ammonia absorption in a spray tower

Abstract: We did an experimental study on ammonia absorption in a spray tower. The kinetic characteristics of droplets were investigated by considering the forces acting on a droplet. The gas-phase mass transfer coefficient was deduced with the Colburn analogy method. A simplified model for predicting NH3 capture with a spray tower has been presented based on mass transfer and ionic equilibrium, which was successfully validated against experimental data. The influences and the sensitivity analysis of main operating parameters on the absorption efficiency were analyzed. As the most sensitive parameter, the mean droplet diameter was obtained by fitting experimental data with an empirical correlation. The distributions of two typical process parameters along the absorber were also simulated. Decreasing the pH value of absorbent is an effective but restrictive way to strengthen the mass transfer rate on account of insufficient liquid-side resistance.
