The effective removal of gas phase species relies on effective gas liquid hydrodynamic contact coupling with fast chemical reaction rates. To promote mass transfer rate and the development of reagents, computational fluid dynamic modeling has long been recognized as an effective methodology for the quantification of physical and chemical parameters. The simulation of the gas liquid process involves the coupling of models including multiphase flow, turbulence, interfacial forces, mass transfer, and chemical reactions. The selection of suitable models according to practical applications has been challenging. In terms of multiphase flow, volume of fraction, Euler−Euler, and Euler−Lagrange approaches are discussed. With regard to turbulence, direct numerical simulation, large eddy simulation, and Reynolds averaged Navier−Stokes approach are compared. With respect to interfacial forces, the dominance of drag, lift, virtual mass, wall lubrication, and turbulent dispersion forces for different situations are obtained. In terms of mass transfer, the development and applications of film model, dimensionless analysis, penetration model, and surface renewal model are discussed. Different methodologies to enhance mass transfer include improvement of equipment structure, addition of nanofluid, and exposure to an energy field are summarized. To accelerate the computational process, four methods including the space−time conservation element and solution element model, compartmental model, reduction in dimension, and multiscale approach are discussed. This paper intends to provide a thorough review on the applications of different models to different situations and, in particular, to reveal the restrictions of different models. Overall, this study lays the foundation for future studies on the optimization of scrubbers for large scale practical applications. It also allows a deeper understanding of the interactions of fluid dynamics, mass transfer, and chemical reactions.

“…The jet-cyclone coupling separator is a novel type of mass transfer enhancement equipment with the advantages of simple structure, strong applicability, light equipment, and good mass transfer effect. It has been widely used in deamination, desulfurization, − and other fields. The device utilizes the collision between the rotating turbulent field and the jet field to break the jet into small droplets, thus increasing the contact area between the two phases and enhancing the mass transfer effect.…”

The removal of methyldiethanolamine (MDEA) from solvent naphtha is crucial due to its impacts on pH and the refining process. In this study, the Fluent simulation method was used to study the internal flow field of a jet-cyclone separator to address the limitations of experimental research. The absorption capacity of water and ethylene glycol were compared by batch experiments as a jet-cyclone coupled separation method for MDEA. In addition, the effects of cyclone inlet flow rate, absorbing liquid temperature, absorbing liquid flow rate, and equipment structure on the separation efficiency of MDEA were investigated. The results showed that the comprehensive separation efficiency of MDEA ranged from 81.4 to 95.43%. This work is the first to use a jet-cyclone coupling separator to treat MDEA in solvent naphtha, expanding the gas–liquid mass transfer equipment field, with promising application prospects.

“…In [11], the separation of a gas-liquid two-phase flow is modeled and analyzed with CFD tools by considering a cone as a cyclonic generator; also, the dynamics of a cyclone separator with helical fins is studied by CFD in [12]. In [13], the cyclonic phenomenon is also studied for an absorption separator of ammonia from a liquid solution.…”

An Experimental Analysis of Gas Reduction in Multiphase Flow with a KMS Helical Static Mixer

The separation dynamics of a multiphase fluid mixture is studied with the aim to validate the gas reduction from the mixture by means of a KMS helical static mixer device through a laboratory prototype based on the jet-pump artificial lift system for oil extraction. The study is focused on the cyclone phenomenon, produced by the KMS, to experimentally verify the reduction of foaming in a reservoir behaving as a horizontal gravity separator of an oil–gas–water mixture under specific dynamics conditions of velocity and pressure of an incoming streamline, as well as some physical mounting configurations of the device. The results were numerical and experimentally validated, projecting the real performance in three-phase separators in an oil extraction field to improve efficiency in pumping machines regarding the negative effects of the gas. Concerning the gas reduction, a KMS of two elements located at 100 mm from the entrance of the horizontal reservoir and 20 mm from a gas casing tube successfully improves the gas isolation from the mixture, from 29.2% to practically 0% over 200 min in the reservoir, to let oil and water become separated by sedimentation. This gas reduction is indirectly assessed by the emulsion that is generated, which affects the time of oil separation in the counterbalance.
