Abstract: According to the process characteristics of domestic small-scale refineries, considering the production of low-sulfur heavy marine fuel oil as the direction of transformation, combined with the production process of typical refineries, the experimental study on the blending formula of low-sulfur marine fuel oil was carried out, from the point of view of overall process, the production scheme was studied, and the suitable overall process was customized for the production of low-sulfur marine fuel oil. By comparing and analyzing the processing capacity, input-output and economic benefit evaluation of each scheme, the best technical route suitable for the production of low sulfur marine fuel oil in this refinery was selected, it provided technical support for the refinery to produce low sulfur marine fuel oil, and provided a reference for other refineries to design economically competitive processing schemes.

Key words: low sulfur marine fuel oil, blending, overall process optimization, benefit evaluation
