© 2015 Elsevier Ltd. Oxy-fuel combustion is a promising CCS technology which is being demonstrated prior to commercialization. While the flue gas in oxy-fuel combustion is concentrated in CO2, it contains impurities such as SO2. The elimination of SO2 can provide a clean CO2 stream ready for storage. SO2 is commonly washed by sodium based spray towers with high efficiency but CO2 impacts are significant. A theoretical model was developed based on the two-film mass transfer model, and considering both the SO2 and CO2 reactions with sodium solutions. This model was firstly used to simulate the dynamic experimental results reported in our previous paper to confirm its applicability. With this model, simulations then were carried out on the absorption rate of SO2 into droplets with three droplet sizes: 100µm, 500µm and 1000µm, one sodium concentration of 0.08M (back calculated from liquid analysis), a range of pH from 4 to 12.5 and a range of SO2 concentrations from 19ppm to 1500ppm.Simulations focus on the impacts of droplet position, gas phase CO2 and droplet size on the absorption rate of SO2. These impacts are closely related with pH values. Taking a typical pH of 7 for example, the absorption rates of SO2 for droplets close to nozzles which move relative to the gas are significantly higher than these below nozzles which are at the terminal velocities, and the differences between two positions are larger for higher concentrations of SO2 with the concentrations range from 200ppm to 1500ppm. CO2 has a negative impact on the absorption rate of SO2 through reducing the gas phase mass transfer coefficient of SO2 in the gas phase controlled region and also through generating more acidic conditions at the liquid phase interface. Reducing the droplet size from 500µm to 100µm has a more significant improvement on the absorption rate of SO2 than from 1000µm to 500µm. Result: have implications in the controlling region and the operational liquid pH region. The controlling region is related to the droplet position. The droplets close to nozzles are located in the mixed controlled region or the gas film controlled region; and the droplets below nozzles can be located in three regions depending on the concentration of SO2 and pH. A lower concentration of SO2 and a higher pH are favourable for the absorption rates of SO2 to be located in the gas phase controlled region.The operational pH of the exit liquid may be established based on two criteria: a reasonable absorption rate of SO2 and a sodium reagent loss as NaHCO3. The optimal operational region is then in the region 2 where the absorption rate of SO2 is still high and reagent use is minimized. The region 2 can be further divided into four sub regions. In the region 2-1 and the region 2-2, the absorption rate is moderate, but there is too much Na+ wasted for CO2 capture. In the region 2-3, there is a moderate amount of Na+ wasted for CO2 capture. In the region 2-4, Na+ wasted for CO2 capture is minimized, but the effective ratio of Na+ is still not the maximum.The necessary operational pH region graph can be used to guide the operation of a spray tower.

© 2014 The Institution of Chemical Engineers. In a chemical looping combustor (CLC) system, the solid circulation rate (SCR) is a key parameter that determines the design, operating conditions and the overall efficiency of the system. In the present work, the gas-solid flow of a CLC cold flow model (10kWth) has been simulated by the computational fluid dynamics-discrete element method (CFD-DEM). The results showed that the SCR at different locations of the system fluctuates with time with different amplitude, and the variation of SCR is periodically stable. The turbulent gas-solid flow regime in the air reactor was found to be the main mechanism driving the fluctuation of SCR and determined the fluctuation frequency and amplitude. The SCR increased with the flow rates of air/fuel reactors and loop seals, and the total solid inventory. Changes in operating conditions directly induced the change in the mass of solids that were entrained into the riser from the air reactor and how fast the solids were transported therein. A correlation was subsequently proposed to describe the SCR as a function of solid hold-up and gas flow velocity in the riser. The particle residence time decreased in a power law as the SCR increased. Reasonable agreements were obtained between simulations and experiments in terms of solid distribution, gas-solid flow patterns, pressure drop profiles and SCR.

The correct calculation of cell void fraction is pivotal in accurate simulation of two-phase flows using a computational fluid dynamics-discrete element method (CFD-DEM) approach. Two classical approaches for void fraction calculations (i.e., particle centroid method or PCM and analytical approach) were examined, and the accuracy of these methodologies in predicting the particle-fluid flow characteristics of bubbling fluidized beds was investigated. It was found that there is a critical cell size (3.82 particle diameters) beyond which the PCM can achieve the same numerical stability and prediction accuracy as those of the analytical approach. There is also a critical cell size (1/19.3 domain size) below which meso-scale flow structures are resolved. Moreover, a lower limit of cell size (1.63 particle diameters) was identified to satisfy the assumptions of CFD-DEM governing equations. A reference map for selecting the ideal computational cell size and the suitable approach for void fraction calculation was subsequently developed. © 2014 American Institute of Chemical Engineers.

On 29th January 2010, a tragedy took place before the blissful Chinese Lunar New Year. An old tenement building in Ma Tau Wai collapsed in a sudden, causing 2 deaths and 4 injuries. Not only did this raise people's concerns to investigate the reasons the collapse of the tenement building, it also raised their awareness on old tenement buildings as well as protecting them from collapsing. In view of this, this paper investigates on condensation and how it might shorten the service life of that old tenement building. © (2014) Trans Tech Publications, Switzerland.
