For a diesel-gasoline mixed hydrogenation unit, is there a significant impact on the product after stopping gasoline feed? What would be the impact if gasoline supply were stopped and all remaining processing volume were switched to diesel? Seeking advice
Increasing the proportion of gasoline in the mixture usually involves adjusting the raw materials used in the plant in order to reduce energy consumption; both are processed together. When only diesel is produced, factors such as the properties of the catalysts used earlier, as well as temperature control in the stabilization and distillation towers, come into play. Generally, no light oil phases form, which makes it difficult to control the temperature later on. This poses a challenge in ensuring the quality of the diesel product. Moreover, the layout of the trays in the towers may not be suitable for operating at a load focused solely on diesel production.
