“…A slightly asymmetric profile is present, which may be either due to the influence of the probe or due to entrance effects. In agreement with results of other workers [8,9], the mean gas holdup increases with increasing energy dissipation rates, which may be due to increased gas dispersion. …”

Mass Transfer and Hydrodynamic Aspects of Kinetics Studies in Light Oil Sweetening: A Review

et al. 2016

LPG (liquid petroleum gas) sweetening is a very important refining process in which mercaptans are extracted from LPG by caustic solution, resulting in mercaptide salts. Subsequently, these mercaptides are oxidized in the presence of air and catalyst to disulphides involving gas liquid (G‐L) reactions in an oxidizer. This review discusses design and operational aspects of a laboratory G‐L oxidizer which are essential for determination of intrinsic kinetic parameters of the mercaptide oxidation step. These kinetic parameters are subsequently used for scale‐up and design of grass root industrial scale oxidizers. The sweetening is categorized as a slow reaction. Hence, reaction takes place both in the film and the bulk. Transport of oxygen across the air to the aqueous alkaline phase in the oxidizer is critical and controlled by the liquid film mass transport term. Thus, oxygen transportation limitations need to be overcome and ensured before conducting kinetic studies. This paper fills the gap between laboratory reactor design and operational aspects by presenting a detailed review on chemical engineering analysis for maximization of the volumetric mass transfer coefficient using operational aspects of an agitated sparged G‐L reactor.
