Venturi system widely utilizes in industrial applications to clean the gas and reduces pollutions. Therefore, many studies have been conducted, especially in terms of pressure drop because it is one of the main parameters to determine its efficiency. But the phenomenon of mass transfer in the venturi scrubber did not get much attention. In this work, mass transfer was studied through a two-dimensional simulation of cleaning the gas produced by the gasification of biomass in Venturi scrubber with boundary conditions represented in air inlet velocities of 10, 15, and 20 m/s and water inlet mass flow of 0.02,0.04 and 0.06kg/s. Navier-Stokes equations were solved numerically and the mass transfer technique was treated by the Volume Of Fluid (VOF) model, using CFD software. The mass fraction, velocity and pressure contours, and profiles, were presented to analyze the obtained results. Also, the Probability Density Function (PDF) of mass transfer was investigated. The results show that the proposed venturi has the best mass transfer performance with a PDF that reaches 97.67 for velocity liquid of 20 m/s. In addition, the removal efficiency is higher with the decrease of liquid flow rates.

Abstract


Venturi system widely utilizes in industrial applications to clean the gas and reduces pollutions. Therefore, many studies have been conducted, especially in terms of pressure drop because it is one of the main parameters to determine its efficiency. But the phenomenon of mass transfer in the venturi scrubber did not get much attention. In this work, mass transfer was studied through a two-dimensional simulation of cleaning the gas produced by the gasification of biomass in Venturi scrubber with boundary conditions represented in air inlet velocities of 10, 15, and 20 m/s and water inlet mass flow of 0.02,0.04 and 0.06kg/s. Navier-Stokes equations were solved numerically and the mass transfer technique was treated by the Volume Of Fluid (VOF) model, using CFD software. The mass fraction, velocity and pressure contours, and profiles, were presented to analyze the obtained results. Also, the Probability Density Function (PDF) of mass transfer was investigated. The results show that the proposed venturi has the best mass transfer performance with a PDF that reaches 97.67 for velocity liquid of 20 m/s. In addition, the removal efficiency is higher with the decrease of liquid flow rates.
