Design and Simulation Based Structural and Thermal Analysis of a Pilot Scale Bio Based Grease Reactor

Abstract

The growing need for environmentally friendly lubricants has spurred the development of bio-based grease production technology. In accordance with ASME guidelines, a pilot-scale grease reactor was built using SS304L material and pine needle oil as a renewable base fluid. In order to demonstrate efficient temperature control and durability at a cost-effective level, this design strives for low construction costs, ease of operation, and appropriateness for small-scale production. The study was conducted in August 2022 and November 2023 at Gobind Ballabh Pant University of Agriculture and Technology, Department of Farm Machinery and Power Engineering. The reactor's features included a dual impeller made up of a 45° pitched turbine blade and a traditional anchor agitator, as well as a tori spherical bottom dome for effective mixing and structural stability. SolidWorks 2021 and Ansys R19.2 were used for structural and transient thermal analyses in order to guarantee mechanical integrity, structural strength, and uniform temperature distribution from the vessel to the liquid. Heat distribution and energy efficiency are improved via an exterior casing and peripheral heating coil. It has been determined that because the material SS304L can withstand the loads, its stress and strain values are ideal for producing pilot-type reactors. The design showed the strongest resistance to heat and external loads. It was determined that, at an approximate cost of Rs. 47522, low construction costs, ease of operation, suitability for small-scale production, and effective temperature control and durability are achieved.
