Gasoline hydrogenation diene addition
Thread Content
In a gasoline hydrogenation unit, the pre-hydrogenation reactor is used for the addition reaction of dienes. Within the normal operating range, is it true that the higher the hydrogen-to-oil ratio, the better?
Of course, the higher the gasoline ratio, the better, but the load on the cycle also needs to be taken into account; generally, a slightly higher value is sufficient
Check the content of diene in the raw materials at the time of design, as well as the hydrogen-to-oil ratio; adjust this ratio based on the actual diene content. Also analyze the hydrogen content in the gas from the pre-distillation tower – it is usually around 60%, which is too high and not useful, representing a waste
