Improving the efficiency of the gas purification unit of the diesel fuel hydrotreating unit

This article discusses the possibility of increasing the efficiency of the gas purification unit of a gasoline and diesel fuel hydrotreating unit. According to statistics, since the beginning of 2022, the hydrogen sulfide content in gases from the diesel hydrotreating plant is 1.46...3.28% vol., which indicates the inefficient operation of the VS-101 screw mixer. Therefore, in order to increase the degree of gas purification, the installation of a new absorber is being considered. To assess the implementation of this activity, technological calculations were carried out in the Petro-SIM software. An investment assessment was carried out with the determination of the main economic indicators.
