中国石油网消息：4月中上旬，兰州气温回暖，春意盎然。一辆辆满载黑色石油焦的货车缓缓驶出兰州石化延迟焦化装置装车点，准备发往下游新能源企业。

China Oil News: In the early to middle of April, the temperature in Lanzhou rose, and the spring atmosphere was abundant. A series of trucks loaded with black petroleum coke slowly left the loading point of the delayed coking unit of Lanzhou Petrochemical, preparing to be sent to downstream new energy enterprises.

“你看这焦炭的外观，孔隙均匀、结构致密，用作预焙阳极，品质可是稳得很！”刚刚接班的炼油三部焦化班长刘旭升指着刚除焦下来的石油焦说道，“以前这石油焦每吨卖不到1000元，现在我们通过技术创新，产品质量稳定保持在3A级，每吨价格涨到3500元以上，是咱们增效的‘金疙瘩’。”

"Look at the appearance of this coke - the pores are uniform and the structure is dense. When used as a pre-baked anode, its quality is absolutely reliable!" Liu Xuseng, the new shift supervisor of the coking section of the Oil Refining Department 3, pointed at the petroleum coke that had just been desulfurized and said, "Previously, each ton of this petroleum coke was sold for less than 1,000 yuan. Now, through technological innovation, our product quality has been steadily maintained at the 3A level, and the price per ton has risen to over 3,500 yuan. It is a 'golden treasure' for increasing our efficiency."

面对原油重质化、劣质化趋势加剧以及下游新能源材料市场对高端碳材料需求的激增，兰州石化坚持创新发展，向技术创新要效益，通过精准调控反应参数、维护核心设备，在保障装置长周期稳定运行的前提下，稳步提升焦炭产率，并将其有效转化为更有价值的特种焦，最大程度提升产品价值，在“减油增特”转型浪潮中蹚出了一条新路。

In the face of the intensifying trend of heavy and low-quality crude oil, as well as the sharp increase in the demand for high-end carbon materials in the downstream new energy materials market, Lanzhou Petrochemical has persisted in innovation and development, seeking benefits through technological innovation. By precisely regulating reaction parameters and maintaining core equipment, while ensuring the long-term stable operation of the plant, it steadily increased the yield of coke and effectively transformed it into more valuable special cokes, maximizing the product value. In the wave of "reducing oil production and increasing special products", it has blazed a new path.

第一季度，延迟焦化装置累计生产石油焦超过7.2万吨，收率接近25%，增效400余万元，为完成首季生产任务奠定了坚实基础。

In the first quarter, the delayed coking unit produced over 72,000 tons of petroleum coke in total, with a yield close to 25%. This resulted in an efficiency increase of over 4 million yuan, laying a solid foundation for completing the production tasks for the first quarter.

为了生产出高品质的特种焦，兰州石化成立焦化技术攻关团队，持续优化加热炉出口温度、炭塔反应压力等重要工艺参数，根据原料性质，动态调整循环比，使重质原料在焦炭塔内完成充分的热裂解与缩合反应，显著提升石油焦产出效率。同时，通过运用加热炉炉管特殊涂层技术、优化水力除焦参数防止焦炭黏结，建立实时监测系统，对炉管温度、压力变化进行动态追踪，确保装置在高负荷状态下平稳运行，单日产出石油焦达900吨。

In order to produce high-quality special coke, Lanzhou Petrochemical established a technical research team for coking, continuously optimizing important process parameters such as the outlet temperature of the heating furnace and the reaction pressure of the carbon tower. According to the properties of the raw materials, the circulation ratio was dynamically adjusted to enable heavy raw materials to undergo sufficient thermal cracking and condensation reactions in the coke tower, significantly improving the output efficiency of petroleum coke. At the same time, by applying special coating technology for the furnace tubes of the heating furnace, optimizing the hydraulic desulfurization parameters to prevent coke from adhering, and establishing a real-time monitoring system to dynamically track the changes in furnace tube temperature and pressure, the plant was ensured to operate stably under high-load conditions, with a daily output of petroleum coke reaching 900 tons.

增产只是第一步，将产量优势转化为品质胜势，才能真正拿到创效的“金钥匙”。兰州石化组织专题研讨10余次，深入分析原料特性、工艺参数等关键影响因素，结合延迟焦化装置实际，制定详细的特种焦试生产方案，并与兰州相关新能源材料公司开展深度合作，整理分析各项操作数据，反复优化工艺参数与原料配比，全力推进石油焦提质增效。

Increasing production is only the first step. Converting the production advantage into a quality advantage is what truly holds the key to achieving efficiency gains. Lanzhou Petrochemical organized over 10 special discussions, thoroughly analyzing key influencing factors such as raw material characteristics and process parameters. Based on the actual situation of the delayed coking unit, they formulated a detailed trial production plan for special cokes, and carried out in-depth cooperation with relevant new energy material companies in Lanzhou. They sorted and analyzed various operation data, repeatedly optimized process parameters and raw material ratios, and fully promoted the improvement and efficiency enhancement of petroleum coke.

“与常规石油焦生产不同，特种焦对产品的挥发分、真密度、灰分等指标有着更为严苛的要求，任何一项参数偏离都会影响下游新材料的性能。”焦化区域工艺工程师宋福荃介绍道。

"Unlike conventional petroleum coke production, special coke has more stringent requirements for indicators such as volatile matter, true density, and ash content of the product. Any deviation in any of these parameters will affect the performance of the downstream new materials," said Song Fuchuan, the process engineer of the coking area.

为了不影响装置高负荷运行和月度产量任务，技术团队在原料性质相对稳定的时段进行梯度调整，利用在线分析仪表实时监测关键指标变化情况，将每一次调整都转化为可量化的数据积累，最终在保障产量的同时，让石油焦挥发分稳定小于11%，产品质量稳定符合3A级高品质标准。

In order not to affect the high-load operation of the equipment and the monthly production targets, the technical team carried out gradient adjustments during periods when the raw material properties were relatively stable. They used online analytical instruments to monitor the changes in key indicators in real time, converting each adjustment into quantifiable data accumulation. Eventually, while ensuring the production volume, they managed to keep the volatile matter of the petroleum coke below 11%, and the product quality remained stable and met the 3A-level high-quality standards.

目前，兰州石化坚持以技术为核心，持续强化科技创新驱动，通过原料预处理优化、工艺参数精准调控、高端产品研发迭代，进一步提升石油焦增产潜力与价值空间，让这些“黑色黄金”成为新能源产业的强劲动能。

At present, Lanzhou Petrochemical adheres to taking technology as the core and continuously strengthens the driving force of scientific and technological innovation. Through optimizing raw material pre-treatment, precisely regulating process parameters, and iterating on high-end product research and development, it further enhances the potential for increasing the production of petroleum coke and the value space, making these "black gold" a powerful driving force for the new energy industry.
