The ZCP13 cationic polyester project of Xin Fengming Group, undertaken by the headquarters of China Kunlun Engineering Co., Ltd., with the participation of three branch companies in Shenyang, Liaoyang, and Liaojin. The successful commissioning of this facility marks another 'national heavy weapon' in China's high-end fiber materials field.

As a benchmark project for the domestic production of 250,000 tons of fiber-grade cationic modified polyester annually, the Zhonghong ZCP13 facility bears the strategic mission of promoting the upgrade of new textile materials. The production process of cationic polyester is complex and requires precise control of reactions such as esterification and polycondensation under high temperature and pressure conditions. The facility includes 5 reactors and over 200 dynamic and static equipment pieces, with a pipeline system that crisscrosses throughout, making the design challenging.

Facing the extremely tight overall project schedule requirements, the Shenyang branch team met the challenge with a "starting at full speed" attitude. They had to complete the design of the entire 23,000-meter high-pressure piping system for the facility during the design phase from February to September 2024, covering three core sections: esterification, pre-polycondensation, and final polycondensation. This is equivalent to completing 120% of the work in only 60% of the time typically required for a regular project.

In early spring February 2024, a race against time has quietly begun in Shenyang. The Shenyang branch has formed a cross-departmental task force, breaking down the design tasks into three major battles: optimizing process pipelines, building 3D models, and accurately reporting materials. The design team creatively adopted a "rolling delivery" model, dividing the 23,000 meters of pressure pipelines into five layers for simultaneous advancement, and dynamically matching the 3D model with the construction progress through PDMS software.

The project has entered "wartime mode": The equipment pipeline system is divided into three sections: process main flow, utility engineering, and thermal media engineering. Using a "modular design + phased delivery" strategy, it achieves efficient collaboration through batch submission of drawings, segmented material procurement, and interspersed construction progress.

With the "5+2" and "white plus black" fighting spirit, the project team completed all 2,800 drawings on schedule and delivered them in batches. The materials list for 23,000 meters of piping was also submitted for procurement on time and in batches, securing valuable time for on-site construction.

At the construction site, the "Kunlun speed" is also being demonstrated. In response to the challenges of limited space within the building and frequent cross-operation tasks, the design team has deployed one key member to be stationed on-site constantly, while other members provide timely support. They carry out daily clearance and settlement-style对接with the construction team, assisting in solving technical issues such as pipeline collision and support positioning to ensure the project is implemented with zero errors.

As a model project of CNPC's "integration" strategy, the ZCP13 facility fully demonstrates the efficiency and advantages of group operations. The Shenyang Branch Pipe Specialty collaborated closely with relevant specialties such as process, structure, equipment, automation control, and electrical at the headquarters, as well as LiaoYang and LiaoJin branches, timely resolving key issues such as interface demarcation. In optimizing the layout of the facility core area, experts from the headquarters personally guided the project team on-site, ensuring the core issues were addressed.

More notably, the project全程 applied the digital delivery platform independently developed by Kunlun Engineering, achieving project cycle management for the pipeline component library and stress calculation models. This not only ensured the project schedule but also established replicable standardized operating procedures, saving at least 30% of design hours for subsequent similar projects.

The successful commissioning of the ZCP13 facility is another milestone in Kunlun Engineering's mission to serve the country through technology, pulsating with the strong heartbeat of the ethnic fiber industry's upward advancement. In the future, this team, which excels in tough battles and dares to forge new paths, will continue to compose new chapters of glory on new "battlefields" with their craftsmanship and wisdom.

The High-End Polyester New Materials Industry Chain Forum will be held in Hangzhou on April 25, 2025. The conference is hosted by Asia Chemical Consulting and will explore various high-end polyester new materials and their key raw materials' industrial policies and market trends, the latest technologies and commercialization progress, the cost and environmental competitiveness of different route technologies using chemical methods and bio-based methods, investment in new projects, upstream and downstream integration, performance and competitiveness comparison of high-end polyester new material products, and development of high-end downstream applications. Leaders and experts from China Kunlun Engineering Co., Ltd. will attend and give keynote reports.
