Yangzi Petrochemical’s carbon monoxide plant sets a record for stable operation
Thread Content
On October 15, as the carbon monoxide unit in the syngas workshop of Yangzi Petrochemical’s aromatics plant ceased to export products, it completed its phase of stable operation, achieving 466 days of continuous and safe operation – the longest operating period recorded since its commissioning 15 years ago. This facility came online in 2010 and is Sinopec’s only facility for converting natural gas into syngas. Due to complex process conditions and limitations in the initial design, the operational stability of the device needs to be improved. Yangzi Petrochemical attaches great importance to the efficient and long-term stable operation of this unit; it takes the lead in carrying out technical research to provide decision-making support for the continuous optimization of the unit. The aromatic compounds plant focuses on the key issues that affect the stable operation of its equipment, establishing a three-level responsibility structure with plant management taking overall oversight, workshop staff handling day-to-day tasks, and teams responsible for implementation. Through a management approach that emphasizes meticulous routine maintenance, precise special care for the equipment, and dedicated teams for tackling technical challenges, the plant formulates long-term operation plans to address complex and difficult issues. In the face of the challenges associated with the end of the operational life cycle of the equipment, the syngas plant adheres to a strategy of \"stability and prevention,\" establishing a comprehensive control system that combines \"management improvements\" with \"hardware support.\" In addition, by leveraging small-scale index competitions, efforts to optimize benchmarking are continued. In light of the frequent changes in natural gas composition, Party member leaders were organized to develop operation manuals, thereby facilitating a steady improvement in various indicators such as comprehensive energy consumption; among these, the indicator for carbon monoxide consumption per unit of natural gas is the best in the group company. Ongoing exchanges through \"going out\" and \"bringing in\" initiatives are carried out; technical seminars on the long-term stable operation of the facilities are organized, and 6 optimization measures for such stable operation are implemented to provide technical support for improving the stability of the facilities.
2024-11-05 14:02 As of now, Yangzi Petrochemical’s carbon monoxide production unit has been operating safely using a new domestic catalyst for over 3 months. The operation results show that the methane conversion rate is over 93%, indicating that the performance of the newly developed domestic catalyst meets the requirements of the plant’s process. This marks the first industrial application of a high-activity multi-feed steam reforming catalyst combination, developed and produced independently by Sinopec, in a carbon monoxide plant, which effectively promotes the localization of this type of catalyst and enhances the operational efficiency of such plants. For a long time, due to factors such as high reaction temperatures and harsh production conditions, domestic carbon monoxide plants have used imported catalysts. In recent years, Yangzi Petrochemical and the Research Institute of Qilu Petrochemical have strengthened technical exchanges, testing and applying the highly active catalysts successfully developed by the latter institute. It is estimated that, compared with the imported catalysts used in the previous period, the replacement with this new domestic catalyst not only significantly reduces the procurement cost but also shortens the procurement cycle from over 6 months to just 1 month.
