Abstract: With the increase of energy demand, the accurate determination of sulfur content in crude oil has attracted more and more attention, because the sulfur content directly affects the quality of crude oil and the environmental pollution level of refining process. In this study, the sulfur content in crude oil was analyzed by tube furnace method, and the accuracy and reproducibility of the method were discussed. By optimizing the experimental conditions such as furnace temperature setting (900˚C~950˚C) and carrier gas flow rate, the reliability and accuracy of the measurement are ensured. Based on the analysis of multiple batches of crude oil samples, the standardized operation process of the tube furnace method was established, and the stability of the method was verified by repeated experiments. The experimental results show that the optimized tube furnace method has high sensitivity for the detection of sulfur content in crude oil, and the detection limit can reach tens of μg/g, which provides a scientific basis for the classification, trade and processing of sulfur content in crude oil. In addition, based on the measured sulfur content data, this study estimated the potential emissions of sulfur oxides during crude oil combustion or refining, and evaluated its environmental impact, providing theoretical basis and data support for refineries to develop more environmentally friendly processing strategies. This research is of great significance to ensure the quality and safety of oil products, reduce environmental pollution and promote the transformation of green energy.
