Gas-Phase Mass Transfer in Cocurrent Gas-Liquid Contact Operations on a Vertical Flat Wall

Study on Mass Transfer Enhancement in a Gas-Liquid System Using Nanomaterials

The main objective of this paper is to examine the effect of nanomaterials on mass transfer coefficient in bubble type absorption of carbon dioxide by experiment. The absorption process is carried out in a bubble column and in room temperature. Mass transfer coefficient, saturated concentration of CO2, and gas holdup are determined in this system. The kinds of nanomaterials, the concentrations ...

Liquid mixing and gas–liquid mass transfer in a three-phase inverse turbulent bed reactor

In this research work, hydrodynamic characteristics and gas–liquid mass transfer in a laboratory scale inverse turbulent bed reactor were studied. In order to characterize internal flow in the reactor, the residence time distribution (RTD) was obtained by the stimulus-response technique using potassium chloride as a tracer. Different solid hold-up (0–0.37) and air superficial velocity (2.7–6.5 ...

Mass Transfer in a Closed Stirred Gas / Liquid Contactor Part 1 : The Mass Transfer Rate

Liquid phase mass transfer rates kLS for the absorption of oxygen in tap water and in aqueous ionic solutions have been determined in two closed stirred tank contactors for a power input between 3 and 70 W/kg and (impeller diameter)f(tank diameter) ratios DifT of 0.3, 0.35 and 0.4. The contactors had diameters of 0. I9 and 0.6 m. The dispersed phase fraction was 1% by volume in all experiments....
