Chemical Processes are widely carried out by means of heat. Heat is used to maintain viscosity of fluid that is stored. Naphtha is heavy oil which is stored in process reactionary vessel. If the temperature drops the fluid becomes viscous and can cause considerable damage to the system. To overcome this problem the embedded pipes are introduced in the system which maintain the temperature of the system. Present research work proposes the two designs of embedded heat pipes into the system. The pressure vessel is designed using ASME standards and modeling is done on the ANSYS design modeler. FEA Simulation is carried out using different cases to check the total deformation and stress and select the optimized design. The result shows that the U-shaped embedded pipe gives less deformation and stress than the C-shaped embedded pipe.
