Parametric and Computational Fluid Dynamics Study on Improving the Design of a Degumming Reactor

Abstract:

Crude palm kernel oil (CPKO) is a vital industrial and domestic commodity, yet its high level of impurities limits its direct use without refinement. Degumming is a fundamental step in refining, requiring efficient mixing, heating, and removal of phospholipids. In this study, parametric design principles and computational fluid dynamics (CFD) were applied to optimise the geometry and performance of a degumming reactor. Different height-to-diameter ratios (Rh/d = 1.0, 1.05, 1.10, 1.15, and 1.20) were analysed to determine their effect on fluid dynamics, velocity distribution, and thermal uniformity. CFD simulations were conducted using ANSYS Fluent, supported by heat transfer analysis and descriptive statistics, to identify the most efficient configuration. The findings demonstrate that an Rh/d ratio of 1.05 offers the best hydrodynamic stability and thermal performance, making it suitable for small and medium-scale refinery operations. This integration of CFD and parametric modelling highlights the role of digital engineering in improving food process equipment for resource-constrained industries.
