今年一季度，华北石化生产航空煤油37万吨，向北京大兴国际机场保供航煤34.6万吨，产销量均创历史新高。

今年年初以来，华北石化坚持以航煤生产为主线，紧紧抓住“国内经济复苏、民航运输回暖”的有利时机，统筹安排航煤增产扩销工作，加强生产受控管理，持续生产优化攻关，推进产运储销高效衔接，提升目标产品收率，实现了航煤稳产增产。

华北石化锚定提质增效目标，优化运行航煤生产主力装置——加氢裂化装置，着力提高生产效能。面对氢气管网与中压蒸汽管网的紧平衡，岗位人员进一步优化操作，调整反应器各床层温度以及分馏系统操作，同时在各班组开展“非必要不加氢”劳动竞赛，收窄指标范围，使航煤收率由设计值42.8%逐步提高至47%，日产量达2200吨以上，实现了装置低负荷下航煤稳产增产。

为提高航煤产品分析准确性，华北石化对照CNAS体系运行标准，持续开展体系内审工作，持续强化航煤产品分析的全流程管控。3月26日，华北石化中心化验室与中国航油华北公司油研中心开展技术交流，从航煤样品的制备、流转、操作流程及仪器设备使用维护等多维度进行研讨分析，最大程度消除各检测环节潜在的影响因素，确保检测数据准确无误。

In the first quarter of this year, North China Petrochemical produced 370,000 tons of aviation kerosene and provided 346,000 tons of aviation coal to Beijing Daxing International Airport, with production and sales reaching a record high.

Since the beginning of this year, North China Petrochemical has adhered to the production of aviation coal as the main line, firmly seized the favorable opportunity of "domestic economic recovery and civil aviation transportation recovery", coordinated the production and expansion of aviation coal, strengthened production control management, continued to optimize production, promoted the efficient connection of production, transportation, storage and sales, and improved the yield of target products, achieving stable production and increase of aviation coal.

North China Petrochemical Company set the target of quality improvement and efficiency improvement, optimized the operation of the main equipment of aviation coal production - hydrocracking unit, and focused on improving production efficiency. In the face of the tight balance between the hydrogen pipe network and the medium-pressure steam pipe network, the staff further optimized the operation, adjusted the temperature of each bed of the reactor and the operation of the fractionation system. At the same time, the labor competition of "no unnecessary hydrogenation" was carried out in each shift and group, narrowing the index range, gradually increasing the jet coal yield from the design value of 42.8% to 47%, and the daily output reached more than 2,200 tons. The stable production and increase of jet coal under low load of the unit were realized.

In order to improve the accuracy of aviation coal product analysis, North China Petrochemical continued to carry out the internal audit of the system against the operating standards of the CNAS system, and continued to strengthen the control of the whole process of aviation coal product analysis. On March 26, the laboratory of North China Petrochemical Center carried out technical exchanges with the Oil Research Center of North China Company of China Aviation Oil Corporation, and discussed and analyzed the preparation, circulation, operation process and the use and maintenance of instruments and equipment of aviation coal samples, so as to eliminate the potential influencing factors of each test link to the greatest extent and ensure the accuracy of test data.
