Currently, the national energy structure, industrial structure and economic structure are undergoing a deep transformation towards green and low-carbon. In recent years, Nanjing Yangzi Petrochemical Co., Ltd. has launched a refining restructuring project to optimize production efficiency and strive to reduce energy consumption and emissions. The project includes large-scale key projects such as the new construction of 2.6 million tons/year of residual oil hydrogenation and 2.8 million tons/year of catalytic cracking. Against this background, Roxtec, as an industry expert in cable and pipe penetration sealing systems, provided customized electrical safety protection solutions for the project. It not only meets the sealing requirements of the installation, but also takes into account design specifications, investment costs and other factors to ensure the safe and stable operation of the cable system. Through the cooperation between the two companies, YPC was able to further improve the overall safety level while safeguarding production efficiency, laying a solid foundation for sustainable development.
Reliable Fire, Water and Air Tightness
In this project, the team in charge put forward strict technical requirements for cable penetration sealing in the walls of buildings such as cabinet rooms and instrumentation control rooms. Through on-site investigation, Roxtec's technicians found that thousands of cables, ranging from 3.5 mm to 50 mm in outside diameter, were intricately laid at each of the penetration nodes, covering a wide range of different types such as telecom, signaling, and instrumentation.
Fire protection was always a priority for the project. As the medium for all power transmission, cables are highly susceptible to fire if they heat up and spontaneously combust or are attacked by open flames from outside. Therefore, the sealing system must have excellent fireproof performance, effectively prevent or delay the spread of fire, for the evacuation of people and fire control time. In addition, the sealing system also needs to have excellent watertight and airtight performance. Any intrusion of hazardous liquids, water, vapors, flammable or harmful gases can cause harm to equipment and personnel, leading to safety incidents. The choice of Roxtec is not just about meeting the needs of daily operations, but also about safety and environmental protection.
Solutions for hazardous areas
The petrochemical industry is unique in that it involves a large number of flammable and explosive substances, so choosing a solution that effectively prevents risks is crucial to ensuring production safety and safeguarding people's lives and property, and Roxtec's products have a high degree of reliability in the field of explosion-proofing, effectively isolating the source of explosions and preventing the risk of explosions and their potential impacts.
As the domestic petrochemical industry pays more and more attention to production safety, companies such as Yangzi Petrochemical are constantly exploring and practicing more advanced anti-explosion designs in building structure design. Roxtec sealing system, with its reliable safety performance, has become the ideal choice for many chemical companies. Not only can it withstand the impact of an explosion, but it also ensures the structural integrity of the building, allowing it to maintain its original blast resistance.
Repeatable open sealing structure
On-site staff introduced, allowing repeated construction is also an important condition for the selection of sealing systems. Because control systems in large petrochemical plants often require replacement or additional cables, cable penetrations should ideally support disassembly and repetitive construction. Roxtec has now set aside 30% spare space for this project. The sealing system utilizes flexible MultidiameterTM modules and an openable frame structure, which allows sufficient spare space to be reserved, so that even in the event of plant expansion or upgrades, site engineers can easily open the frame, relocate the cables, and then close the frame again. The whole construction process is very convenient as there is no need to purchase again and the original structure will not be damaged.
Optimize project cost-effectiveness over the long term
Choosing Roxtec's standardized solutions means significant savings in maintenance and repair costs, and the high stability and durability of Roxtec's sealing systems means that they maintain excellent sealing performance over the long term, reducing power interruptions and additional costs due to equipment failures and damage. This helps to improve the productivity of chemical companies and ensure the continuous and stable operation of production lines.
In the future, Roxtec will continue to work together with YPC to address energy and environmental challenges and promote green and low-carbon transformation. At the same time, they will also continue to optimize their products and services to provide more partners with safe and reliable electrical safety and protection solutions to help achieve the goal of sustainable development.
