SuTong delivers tower internals for China’s largest single-unit L-lactide line

SuTong Technology has supplied the complete tower-internals package for a newly commissioned 100,000-metric-ton L-lactide production line in Dancheng County, Henan Province. The project boosts capacity for biodegradable biomaterials used in medical- and food-grade applications and was highlighted by CCTV for higher conversion rates and lower energy use.

Why it matters: - The new L-lactide line expands supply for biodegradable biomaterials used in medical- and food-grade applications. - The project was identified by CCTV as China’s largest single-unit L-lactide production line. - The commissioning adds industrial capacity in a sector where conversion efficiency, energy consumption, and operational stability directly affect output and cost.

What happened: - SuTong Technology designed and delivered the complete tower-internals package for the L-lactide production line in Dancheng County, Zhoukou, Henan Province, China. - The line has an annual capacity of 100,000 metric tons. - The line began production with SuTong-designed internals supporting mass-transfer and separation processes. - CCTV featured the commissioning and performance improvements in a September 18 report.

The details: - SuTong said the internals support improved product conversion efficiency, lower overall energy consumption, and stronger operational stability and reliability. - CCTV reported higher product conversion rates, lower overall energy consumption, and improved equipment stability and reliability. - CCTV reported that the installation has fully independent intellectual property rights. - The broadcaster said the line can meet requirements for medical- and food-grade applications. - Project photographs from SuTong show dimensional checks on tower distributors inside the process vessels. - The images document the internal assemblies and inspection work at the project site. - SuTong’s work covered the engineering behind the separation equipment used in the production line.

Between the lines: - The project puts SuTong’s separation equipment into a large-scale biomaterials application where performance metrics matter as much as capacity. - The emphasis on lower energy use and higher conversion suggests the line is designed to improve operating economics, not just output volume. - Independent intellectual property rights point to a domestically controlled production platform, which can matter in strategic materials supply.

What’s next: - The commissioned line will now operate as part of China’s broader L-lactide supply chain. - SuTong’s installed internals will be judged on long-term performance in continuous industrial use. - The project could serve as a reference point for future large-scale biomaterials installations.

The bottom line: - SuTong’s tower internals are now part of China’s largest single-unit L-lactide line, a project aimed at scaling biodegradable biomaterials production while improving efficiency and reliability.
