Sustainability in the transportation sector in terms of materials entails many major areas aimed at reducing environmental effect and promoting sustainability over the long haul. Choosing materials that are lightweight, minimizes fuel usage and emission levels from vehicles. In this investigation, Wire Electrical Discharge Machining (WEDM) behavior of AZ61-15wt%ZrC composites was studied. The AZ61-15wt%ZrC composites were made using the stir casting technique. The specimen was created using the WEDM technique from the manufactured composite. By adjusting the input parameters of Current (I) amps, pulse-ON time (T-ON), wire feed rate (WFR), and pulse-OFF time (T-OFF) in s, at four different levels, the manufactured samples were machined via WEDM. L16 orthogonal array was employed in the Taguchi method of experiment design. Analysis of Variance [ANOVA] was utilized to find which process parameter had the greatest impact on output variables like Material Removal Rate [MRR] and Surface Roughness [SR]. WFR is found to be a substantial input parameter on MRR and T-ON on SR, contributing 32.71% and 74.98% respectively.

This study presents an innovative crude oil heating technology by introducing environmentally friendly solar energy into the petroleum industry. By integrating novel combination methods into traditional crude oil heating systems, a versatile and efficient crude oil heating system has been formed. The system was implemented in a refinery and its thermodynamic and economic performance was analyzed. The thermodynamic analysis, employing the exergy analysis method, reveals that among the considered parameters, compressor pressure ratio and Rankine cycle fluid flow rate exert the most significant influence on system efficiency. Overall, the system achieves energy efficiency, exergy efficiency, and waste heat recovery efficiency of 75.99%, 74.13%, and 31.21%, respectively. Within the system, solar collectors, TES tank, and compressor exhibit the highest exergy destruction rates, while pumps demonstrate the lowest exergy destruction rate. The economic analysis, using the annualized cost method, revealed that electricity prices have a significant impact on the economic performance of the system. The variation in system economic parameters is related to the annualized operating cost of the system. The system generates a net annual benefit of 0.591 million US$, with a 4.124-year investment return period. Moreover, Sensitivity analysis explores various factors affecting the crude oil heating system's performance.
