【Petroleum Chemical Craftsman】Zhang Hengzhen – With a secondary vocational education degree, he became the first **technician after 22 years of experience

With only a secondary vocational education, he became a \"technical expert\" in the national ethylene industry”； Having worked in shift-based roles for 22 years, she has achieved the best results among her peers in the country... Zhang Hengzhen, an outstanding employee nationwide, team leader of the compression and separation unit at Sinopec Maoming Branch, and a top-tier technician, is someone who has written a legend as a \"petrochemical craftsman\". As a frontline employee in the petrochemical industry, Zhang Hengzhen pursues excellence in her skills with a craftsman’s dedication, using the cracking unit as a platform to realize her dreams. (Reporter Zhang Yi) A legend from a blank sheet of paper to a \"full-process\" solution. \"The first time I saw the process diagram of the equipment, I couldn’t understand any of the labels marked on the pipelines.\" ”Speaking of her condition at the beginning of her work, Zhang Hengzhen described herself as a blank slate, unable to understand even the most basic process diagrams for equipment. In 1994, Zhang Hengzhen graduated from Lanzhou Chemical School and came to Maoming to work on the 300,000-ton ethylene project; at that time, this key infrastructure project was in full progress. Sinopec Group dispatched a large number of key employees from within its organization to Maoming, and recruited many outstanding graduates from universities; Zhang Hengzhen started far behind. Faced with equipment that was both familiar and unfamiliar, Zhang Hengzhen felt a hint of confusion, but it was quickly replaced by a sense of determination. In Maoming’s first ethylene plant, there are 20 high towers alone, with the tallest one reaching 88 meters. Zhang Hengzhen spent every day on the site, exploring every corner of the installation and climbing all the tall towers; he noted down every detail of it in a notebook and kept it in mind. To study those difficult-to-understand symbols in the flowcharts and the **small devices** set up on site, she borrowed more than a dozen technical books, and the notebooks filled with her notes stacked up over two feet high. “Everyone says Zhang Hengzhen is a copier. ”Recalling his days of studying, Shi Jianbo, a worker in the pyrolysis workshop who started working at the factory alongside Zhang Hengzhen, said, “There were frequent tests back then, and Zhang Hengzhen’s test papers were almost identical to the correct answers.” ” Before the start-up of the Maoming ethylene plant in 1996, Zhang Hengzhen had already become the first \"expert\" on the cracking unit, capable of answering any questions, and thus became the key figure in the startup operations. Today, Zhang Hengzhen is not only an expert in the individual steps of a process but also in the entire process as a whole; she is capable of operating all 8 positions in a million-ton ethylene production facility ； She probably remembers the parameters for over 12,000 positions in the pyrolysis workshop.
Pursuing excellence in craftsmanship with a \"craftsman’s heart.\" Party members are not only a commitment and an honor, but also a banner and a standard. ”As a Party member, Zhang Hengzhen has always been aware of the responsibilities that lie on his shoulders. There is a \"legend\" circulating at Maoming Petrochemical: Zhang Hengzhen maintains a record of \"zero errors\" in his operations! For 22 years, Zhang Hengzhen has consistently worked in the carbon dioxide hydrogenation operation role within the separation and compression system. This is the most \"sensitive\" and \"rebellious\" position in the cracking unit; the slightest carelessness can cause the reactor’s temperature to soar, leading to the shutdown of the unit. During Zhang Hengzhen’s shifts, the carbon dioxide hydrogenation reactor was surprisingly \"well-behaved,\" with no instances of issues affecting production or quality; as a result, Zhang Hengzhen became the undisputed best operator for this reactor. Over 22 years, Zhang Hengzhen incorporated his years of practical knowledge and experience into systematic operation methods, continuously refining and improving them to develop a set of unique operating procedures for the 1# Pyrolysis Unit separation system, characterized by the features of Maoming. This set of procedures has now become a \"guidebook\" for Maoming Petrochemical in training ethylene workers and resolving daily operational challenges. Over 22 years, Zhang Hengzhen proposed and took part in addressing 9 major issues that affected the long-term operational efficiency of the ethylene plant, generating direct economic benefits of 246 million yuan for the enterprise. Thanks to her and her colleagues’ efforts, Maoming Petrochemical’s cracking unit has won first place in competitions among similar units within Sinopec for 8 consecutive years. Maoming Petrochemical’s ethylene production facility has been awarded the title of “National Energy Efficiency Leader Enterprise in the Petroleum and Petrochemical Industry” for three years in a row, while its cracking workshop has received the title of “National Model Worker Unit”. The series of problem-diagnosis and technical solution methods she developed have now been included in technical manuals, serving as an important \"blueprint\" for Maoming Petrochemical in addressing similar technical challenges. In order to pass on the operational knowledge he had acquired, Zhang Hengzhen compiled the \"Separation System Simulation Operation Manual,\" expanded the question bank for distillation operations in ethylene plants by adding 2,520 questions, and wrote a training textbook on aliphatic hydrocarbons for Sinopec totaling over 80,000 words. He also gave lectures four times at Sinopec’s advanced technician training courses for aliphatic hydrocarbons, and trained 51 apprentices personally. Today, her students are found in major ethylene production enterprises across the country, with many of them becoming key technical professionals in China’s ethylene industry.
I also started working at a petrochemical plant in 1994; by comparing others to myself, I feel ashamed. :L
It was also very tough. Zhang Hengzhen spent every day on the site, exploring every corner of the installation and climbing up all the tall towers; he noted down every detail of it in a notebook and kept it in mind. To study those difficult-to-understand symbols in the flowcharts and the **small devices** set up on site, she borrowed more than a dozen technical books, and the notebooks filled with her notes stacked up over two feet high. “Everyone says Zhang Hengzhen is a copier. ”Recalling his days of studying, Shi Jianbo, a worker in the pyrolysis workshop who started working at the factory alongside Zhang Hengzhen, said, “There were frequent tests back then, and Zhang Hengzhen’s test papers were almost identical to the correct answers.” ” Before the start-up of the Maoming ethylene plant in 1996, Zhang Hengzhen had already become the first \"expert\" on the cracking unit, capable of answering any questions, and thus became the key figure in the startup operations.
