The large-scale nitric acid four-in-one unit provided by SHANGU for a project in the aniline-rubber additive industry chain of a large domestic chemical enterprise

Thread Content

The installation of the large-scale four-in-one nitric acid unit provided by SHANGU for a project related to the aniline-rubber additive industry chain of a major chemical enterprise has been completed, and the system is now in the debugging phase. Once operational, this project will have an annual production capacity of 300,000 tons of aniline, providing stable raw materials for downstream enterprises and increasing the added value of their products. Shanxi Gas Turbine developed a customized four-in-one nitric acid production unit and solution for this project. Featuring key advantages such as high efficiency and energy savings, as well as stable operation, it not only provides a reliable power supply for the production process but also enables maximum recovery of excess pressure and heat from the process, thereby significantly reducing overall energy consumption and helping users achieve green, low-carbon, and efficient operations. Recently, the installation of the large-scale four-in-one nitric acid unit provided by Shaanxi Gear for a project related to the aniline-rubber additive industry chain of a major domestic chemical company was fully completed. The unit has now entered the system debugging phase, with all efforts being made to achieve the project’s target date for commissioning. This project is a key local initiative; once operational, it will have an annual production capacity of 300,000 tons of aniline. It will supply stable raw materials to downstream enterprises that produce rubber additives, helping to reduce production costs and increase the added value of their products. This will create a complete industrial chain for aniline–rubber additives, spanning from raw material production to application, thereby further enhancing the competitiveness of the regional industrial chain. Shanxi Blower focused intensely on the process requirements of the project as well as the goals of energy conservation and carbon reduction, and customized a four-in-one nitric acid production unit along with corresponding solutions for the project. This unit has been fully optimized for the operational conditions of the aniline production process; it boasts key advantages such as high efficiency and energy savings, as well as stable operation. It not only provides a reliable power supply for the production processes but also enables maximum recovery of excess pressure and heat generated during these processes, thereby significantly reducing overall energy consumption and helping users achieve green, low-carbon, and efficient operations. From scheme design and equipment manufacturing to on-site installation, the Shaanxi Gas Turbine project team always focuses on user needs, strictly controlling the quality and timelines at every stage of the process. Faced with challenges such as a tight project construction timeline, high requirements for installation accuracy on site, and concurrent operations across multiple processes, Yao Youliang, the on-site service manager at Shaanxi Gas Turbine, led his team to work closely in collaboration with the client. They identified potential risks throughout the installation process in advance, developed specialized mitigation plans, responded to on-site needs 24/7, and completed the installation tasks to a high standard. At present, the unit has fully entered the system commissioning phase. The Shaanxi Blower Team will continue to provide professional technical support throughout the process to ensure a successful first start-up of the unit, thereby safeguarding the smooth commissioning of the project.
