Development of Numerical Eulerian-Eulerian Model for Computational Analysis of Potential in Chemical Process Intensification from Trickle Bed Reactors
The computational fluid dynamics techniques keep a paramount role by evaluating a reactor
performance. The transitory performance of a Trickle bed reactor is readily monitored from its
three phase’s flow conditions. This research review study corresponds towards the formation of
boundaries in this Trickle bed reactors system to designate its comprehensive methodology with
an optimized solution. The main paramount significance of computational fluid dynamics
techniques is to observe the validity and an effective significance of the experimental result. The
catalyst bed is modelled with the help of dynamic and steady state models by introducing mass
and energy conservation equations. The Eulerian-Eulerian multiphase modelling technique is
designed for hydro-desulfurization (HDS) and hydro-dearomatization (HDA) chemical process
change from interactive momentum models. The effect in bed porosity on the HDS reaction
process is observed from interactive mass transfer with solid bed condition in Trickle bed reactor.
The congregated results from computational fluid dynamics codes show that wetting efficiency
increases with increase in both hydrogen sulphide concentration and HDS conversion. The
conversion of HDS reaction decreases with increase in hydrogen disulphide (H2S) concentration at
both partially wetted and wetted bed conditions. On the other hand, there is small decrease in HDS
conversion from 72% to 63.75% at H2S volumetric concentration of 0 to 8%. These observations
also indicate that computational fluid dynamics provides random accessibility of liquid flow in
Trickle bed reactor. There results also reveal that there is periodic variation in saturated liquid
phase. The regions which are close to its wall are less irrigated. These characteristics can be
changed and have effect on the reactor performance. Hence, the present review study presents the
unprecedented results with high accuracy.
