Evaluation of the Quality of Petrol and Natural Gas Fuels

Natural gas and gasoline are essential energy sources for transportation and industries worldwide, and their quality is crucial. This study examines a variety of gasoline and natural gas samples to determine which is better based on important factors such sulfur content, firmness, surface tautness, viscidity, and fattening value. Eight different fuel suppliers provided samples, which were tested in violation of established standards such as ISO 8217: 2017 and GSA 141: 2022. Two suppliers' gasoline samples showed densities that were marginally below the allowed limits, indicating possible adulteration with lower-density materials like kerosene. With the exception of one sample, which also displayed increased sulfur levels, surface tension values for almost all samples remained within permissible norms. Viscosity measurements for fuels from three sources were marginally above suggested standards, perhaps leading to improved pollutant emissions, even though all fuels satisfied the minimum calorific value requirements. Only three providers' goods met the maximum allowable limit of 50 ppm in terms of sulfur concentration, meaning that more than 60% of the examined fuel samples had sulfur levels beyond the allowed threshold. These repercussions highlight the need for ongoing monitoring and more stringent quality control throughout the gasoline supply chain in order to guarantee fuel integrity and environmental compliance.
