In the refining and chemical industry, there are many different technologies for the production of clean gasoline, both light and heavy, but DSO is the most mature of all. On the one hand, the DSO process technology allows for the maximum effect of hydrodesulphurisation of catalytically cracked gasoline, enabling the production of gasoline products that meet national and corporate development needs. On the other hand, the DSO process also allows for maximum octane control of the virgin oil during the catalytic cracking of gasoline, as well as for a safer and more stable system.
The DSO process has the following advantages:
1) It is possible to treat arsenic, which is toxic in its own right, at elevated temperatures, The DSO process allows the catalytic cracking of gasoline to be carried out at normal temperatures, reducing the risk of operation.
2) The DSO process maximises the separation of light gasoline. The DSO technology allows for the precise extraction of the heavy gasoline and the fusion of the required sulphur with the light gasoline.
3) The DSO process minimises the amount of unwanted sulphur in the light gasoline. The DSO process allows the catalyst to be used for a significantly longer period of time, making it easier to achieve the required octane level.
4) The DSO process allows for the removal of excess sulphur from heavy gasoline, enhancing the octane level of the resulting gasoline. The DSO process allows for the removal of excess sulphur from heavy gasoline, which enhances the octane level of the gasoline produced and improves the cleanliness of the gasoline.
