Hainan Refinery's aviation fuel production and yield double increase

Thread Content

Since the beginning of this year, Hainan Refining and Chemical has seized market opportunities and formulated a special plan to increase jet fuel production. Through technical research, operational optimization and other measures, it has promoted both jet fuel production and yield, and accelerated the increase in production and efficiency. In order to break through the bottleneck of jet fuel production, the company focused on the production pain points of the No. 1 hydrocracking unit and set up a special research team. In view of the problem of increased by-product liquefied gas components and affecting the operation of the absorption stabilization tower, the company carried out multiple rounds of technical demonstrations and tests, optimized the raw material structure, adjusted the wax oil processing capacity in the tank area and the blending volume of heavy aromatics, and successfully increased the jet fuel yield of the unit by 1.5 percentage points. At the same time, we will continue to optimize the production load of the No. 1 and No. 2 jet fuel hydrogenation units, steadily increase the processing capacity, and achieve an increase in jet fuel production. In view of the risks of equipment operation under high-load production, we have strengthened grid-based hidden danger inspections, focused on special maintenance and control of key parts such as heating furnace tubes and large units, and established a multi-dimensional quality control mechanism to ensure that the passing rate of jet fuel leaves the factory at 100%.
