“…Figures a–d represent the calculated results on the effect of particle size on collection efficiency at different gas flow rates, constant liquid flow rate 160L/h, and inlet particle loading 30 g/m 3 . The experimentally obtained collection efficiencies were well modeled with foam height H = 0.051–0.083 m and compared with the collection efficiency equation developed by Park and Kaldor . However, their equations were not suitable for predicting collection efficiency in fixed valve tray washing column.…”

“…In recent years, Mohan reported a systematic mathematical approach on the basis of Kim's theory as well as detailed experimental studies on the removal of dust particles from hot gases using a spray column. Park and Lee developed a novel aerosol filtering device, the swirl cyclone scrubber that mainly consists of a cyclone and a swirl scrubber and derived the model of particle collection efficiency due to Brownian diffusion, inertial impaction, and gravitational sedimentation on the basis of Fuchs theory. However, there are none of theoretical models that are especially applicable to the tray columns.…”

in Wiley Online Library (wileyonlinelibrary.com).The goal of this study is to evaluate the performance of a fixed valve tray column designed to remove fly-ash particles. A series of experiments were carried out at room temperature to demonstrate the collection efficiency of a fixed valve tray column at different gas and liquid superficial velocities. The fly-ash particles removal characteristics of the fixed valve tray column were evaluated by measuring variations of concentration and size distribution of particles in the outlet. The mechanism of particle removal in this turbulent dispersion system was theoretically analyzed on the basis of diffusion, interception, sedimentation and impaction, and a model was proposed to predict the collection efficiency. The results show that the simulation results agree well with the experimental data. In contrast to most of the conventional models, the present model is capable of evaluating the effects of bubble hydrodynamics, system property, and operation conditions on the collection efficiency. The model is expected to guide effectively the design and operation of valve tray washing columns, which is widely applied nowadays.

A turbulent wet scrubber was designed and developed to scrub particulate matter (PM) at micrometer and submicrometer levels from the effluent gas stream of an industrial coal furnace. Experiments were conducted to estimate the particle removal efficiency of the turbulent scrubber with different gas flow rates and liquid heads above the nozzle. Particles larger than 1 µm were removed very efficiently, at nearly 100%, depending upon the flow rate, the concentration of the dust-laden air stream, and the water level in the reservoir. Particles smaller than 1 µm were also removed to a greater extent at higher gas flow rates and for greater liquid heads. Pressure-drop studies were also carried out to estimate the energy consumed by the scrubber for the entire range of particle sizes distributed in the carrier gas. A maximum pressure drop of 217 mm H 2 O was observed for a liquid head of 36 cm and a gas flow rate of 7 m 3 /min. The number of transfer units (NTU) analysis for the efficiencies achieved by the turbulent scrubber over the range of particles also reveals that the contacting power achieved by the scrubber is better except for smaller particles. The turbulent scrubber is more competent for scrubbing particulate matter, in particular PM 2.5 , than other higher energy or conventional scrubbers, and is comparable to other wet scrubbers of its kind for the amount of energy spent.Implications: The evaluation of the turbulent scrubber is done to add a novel scrubber in the list of wet scrubbers for industrial applications, yet simple in design, easy to operate, with better compactness, and with high efficiencies at lower energy consumption. Hence the turbulent scrubber can be used to combat particulate from industrial gaseous effluents and also has a scope to absorb gaseous pollutants if the gases are soluble in the medium used for particles capture.
