“…Therefore, this might lead to an improvement of mass and heat transfer processes between the gas and liquid phases. However, the detailed analysis of these mechanisms during CO 2 dissolution is not the focus of this study (Samenov et al 2010;Santos et al 2011;Laugier et al 2008;Chen 2012).…”

The adverse impacts of CO 2 emission on the global warming highlight the importance of carbon capture and storage technology and geological storage of CO 2 under solubility trapping mechanisms. Enhancing the solubility of CO 2 in formation water has always been the focus of research in the area of CO 2 sequestration. Ultrasound techniques are one of the environmentally friendly methods that use high-intensity acoustic waves to improve gas solubility in liquids. Ultrasonic waves can alter the properties of different phases that lead to chemical reactions and provide a means to increase the solubility of CO 2 in connate water. In this study, we investigated the effects of ultrasound on the solubility of CO 2 in connate water under different conditions of pressure, temperature, and salinity. The results showed that the solubility of CO 2 was improved with increasing pressure under ultrasonic effects. However, the solubility of CO 2 was inversely proportional to the increase in brine salinity and temperature. Therefore, it was concluded that the solubility of CO 2 might be enhanced in the presence of ultrasound.

“…1), into the thin liquid film (absorbent) powerful acoustic or ultrasonic (US) oscillations (frequency of 20...250 kHz) is introduced by solid-state transmitter (Khmelev et al 2012;Laugier et al 2008). Ultrasonic vibrations in fluid create acoustic cavitation field (Rozenberg 1968;Khmelev 2011).…”

“…Thus, the effectiveness of atomizing absorbers for these gases is reduced to nothing. Therefore, to solve this problem, it is encouraged by applying of acoustic (ultrasonic) cavitation, the impact of which increases the interfacial surface of the "liquid-gas" (Laugier et al 2008). The acoustic and cavitation influence is effective for the intensification of the processes of absorption that is experimentally proven by domestic and foreign researchers.…”

The paper presents theoretical studies of absorption gas mixture separation under ultrasonic vibrations influence, which provides cavitation and acoustic process intensification. The theoretical studies based on consecutive consideration of this process beginning with single cavitation bubble dynamic which generates shockwave for increasing interface "gas-liquid" and ending with determining absorption productivity providing required concentration of target gas mixture component. In result of the studies, it is evaluated, that cavitation and acoustic intensification increase interface "gas-liquid" up to 3 times with amplitude of oscillations of solid surface 1…2 μm. From the data about surface increasing the analysis of the gas absorption process in the liquid film was performed. For this analysis, the model of gas absorption taking into account surface increasing under acoustic cavitation influence was developed. The model of absorption allows to obtain that the absorption productivity under ultrasonic vibrations influence is increased up to 2 times and more. The obtained results can be used for development of high-efficiency absorption apparatus that is supplemented by ultrasonic influence sources.

In the past, much research has centered on dispersing liquids into gases, and dispersing solids and liquids into liquids. However, there has been almost no research on dissolving gases into liquids by dispersion, possibly because of concerns about the effect of deaeration due to cavitation of a liquid by ultrasound. Here, we consider a method using ultrasound to finely disperse and dissolve a supplied gas. The method entails placing the gas supply outlet close to the tip of an ultrasonic longitudinal vibration source and dissolving the gas into the liquid by finely dispersing the gas by means of the vibrations. In this method, the occurrence of cavitation is reduced as much as possible and deaeration effects are reduced. Here, air is used as the gas to be dissolved and water is used as the solvent. The unsaturated dissolved oxygen concentration in water is used as an indicator for evaluating the proportion of dissolved air. The results show that ultrasonic vibration increases the concentration of oxygen dissolved in the liquid and that almost no deaeration by cavitation occurs.
