Research and Application of Reducing Jet Fuel Inventory in 4.0Mt/a Hydrocracking Unit
Hydrocracking can flexibly produce jet fuel and diesel products to address issues such as high inventory during the off-season of jet fuel.At the end of operation of a 4.0Mt/a hydrocracking unit,under the condition of reaction operation bottleneck,SIMSCI PRO/II software was used to simulate the separation process and adjust the actual operation.The industrial operation results showed that by adjusting the main fractionator operation,jet fuel could be converted by 20t/h to diesel products,and the obtained diesel products met the specification requirements.The cetane number index remained at 55～58.5,and the quality remained stable for a long time.Jet fuel and diesel products from storage area pool could be adjusted to meet the specification requirements also.Zero output of jet fuel products,achieved the goal of reduce inventory of jet fuel throughout the factory,and improved the economic benefits.
