In the fiercely competitive chemical industry, behind every successful project, deep cooperation and complementary advantages between enterprises are indispensable. The cooperation between Baili Technology and Hunan Yuehua New Materials Co., Ltd. (hereinafter referred to as "Yuehua New Materials") is an example in this field.

Over 30 years of working hand in hand

Establish a solid foundation for cooperation

Getting to know each other on WeChat, witnessing each other's growth

Looking back, the cooperation between the two parties began more than thirty years ago. Starting from the initial 5000 ton project cooperation, to 8000 tons, 15000 tons, 20000 tons, 75000 tons, and now the official completion of the 450000 tons/year nylon-6 polymerization project, every increase in production capacity embodies the wisdom and sweat of both parties. During this long period of cooperation, Baili Technology and Yuehua New Materials have worked together to overcome one technical difficulty after another, successfully completing each project and laying a solid foundation for future deep cooperation.

Miracle in the Nylon Industry

Showcasing the Strength of Baili Technology

Project Overview

In June 2023, the cooperation between the two parties reached a new milestone - the 450000 tons/year nylon-6 polymerization project officially started construction. This project is listed as a key construction project in Hunan Province, a demonstration project for investment attraction in Yueyang City, and an extension and expansion project of the petrochemical industry chain. The total investment is 1.8 billion yuan, and the expected annual production capacity of the first phase of the project is 300000 tons. It is of great significance for the chain addition, supplementation, and strengthening of Yueyang's petrochemical industry.

　　Baili Strength

As one of the few construction engineering design companies in China that has simultaneously mastered the engineering design technology of producing caprolactam using toluene method, hydroxylamine phosphate method (HPO), and aminooximation method, and has engineering performance, Baili Technology has demonstrated strong strength in project design and implementation in the three major synthetic material fields of the petrochemical industry. As early as October 2023, the 600000 ton per year caprolactam industrial chain project designed by Baili Technology was successfully launched in one go throughout the entire process. As a "dual point" project between Sinopec and Hunan Province, this project was a large-scale industrial caprolactam industry chain project at that time in China.

The 450000 tons/year nylon 6 polymerization project of Yuehua New Materials is backed by the raw material base of Sinopec. The natural geographical advantage of being separated from the raw material base by only one wall, with short raw material transportation distance and high purity, further assists the project in achieving the uniformity of PA6 slice molecular structure.

　　Project achievements

In February 2025, Yuehua New Materials officially launched a 300000 ton PA6 extinction chip project, with a tested AA rate of over 98.5% and dyeing rate of over 99.6% for 16 spinning heads, delivering a breakthrough answer for downstream spinning customers. At the Yueyang City Investment Promotion Work Conference at the beginning of the year, Zhang Lifen, the chairman of Yuehua New Materials, highly praised this project: "From investment negotiations, household registration and certification, to completion and material feeding, it only took more than a year to create a miracle in the nylon industry's nylon-6 polymerization project at the fastest speed

The industry looks forward to breakthroughs in the future

Deepen cooperation and compose a new chapter

Project Evaluation

Undoubtedly, behind this' miracle 'is Baili Technology's efficient project execution capability and professional technical services. When it comes to the initial intention of choosing Baili Technology for this project, Ou Wenyuan, Vice General Manager of Yue Hua New Materials, first summarized the cooperation experience of the two companies over the past 30 years using the keywords of "harmony, happiness, and success". Furthermore, it was specifically introduced that "Our project is provided with process design by Evanda, while Baili Technology is responsible for civil engineering and related supporting facility design. However, Evanda currently does not have a technical cooperation unit in China, so we must choose a partner with profound technical accumulation and rich project experience to assist in the implementation of its technical parameters. Baili Technology is exactly such a partner

　　Baili Layout

Up to now, in addition to the three major synthetic materials in the petrochemical industry, Baili Technology has continued to make efforts in key core technology research, intelligent production line systems in the new energy industry, and core equipment. It has accumulated thousands of process model library units in different application scenarios in multiple sub fields, as well as a database containing research results on thousands of material properties. Based on the differentiated needs of customers, detailed process parameters can be quickly determined and suitable process models can be adapted to form a complete set of mature process flow and process design packages, reducing customer trial and error costs, shortening the cycle of new and expanded projects, and providing guarantees for customer capacity construction and expansion.

The cooperation between Baili Technology and Yuehua New Materials, from their partnership over thirty years ago to the successful implementation of major projects today, is a collision of technology and strength, a crystallization of trust and tacit understanding. In the future, Baili Technology will continue to leverage its own advantages and work together with more partners to contribute to the development of the chemical industry. With outstanding engineering strength, it will inject more confidence into the market and create more brilliant achievements in the vast world of the chemical industry.
