——Successful on-site lifting of large-scale distillation cold box
Highlights：
1、Lifengas successfully installed the distillation cold box for RIL in India, marking the transition to installation and commissioning of the argon recovery system.
2、The system achieves ≥96% argon recovery with full process integration, reaching internationally leading performance.
3、The project reduces costs via argon recycling and supports low-carbon manufacturing, while expanding Lifengas into the global market.
Project Overview
Recently, the core equipment of a large-scale argon recovery system—the distillation cold box—designed and built by Lifengas for RIL’s solar wafer manufacturing facility in India, was successfully delivered to site and installed.
This milestone marks the transition of the fully integrated photovoltaic value chain project—from quartz sand to modules—into the equipment installation and commissioning phase for its critical gas recycling system.
Installation Progress
As a key environmental supporting project for RIL’s 10 GW integrated solar manufacturing complex, Lifengas’ argon recovery and purification system is designed to enable efficient recycling of high-purity argon used in the crystal growth process.
The distillation cold box installed this time is the most important and precision-demanding core unit of the entire system.
With thorough preparation and professional execution on site, the cold box was positioned accurately in a single lift. The lifting process was safe, stable, and well-organized, earning high recognition from the client and partners.
The successful installation tells that the argon recovery system has formally entered phase of equipment installation and piping works.
Other key equipment, including dust removal and purification units, has also been delivered to site. System integration and commissioning will proceed as planned, laying a solid foundation for early project start-up.
Technical Advantages
Lifengas’ customized argon recovery solution for this project achieves a recovery rate of over 96% under design conditions, reaching internationally leading performance standards.
The system integrates the full process chain, including collection, compression, purification, drying, cryogenic distillation, and reuse, ensuring a stable supply of high-purity argon to the crystal growth process.
This technology represents Lifengas’ core expertise and flagship solution.
Following its successful industrial application in China, this project marks Lifengas’ expansion into the international market.
Sustainability and Value
RIL’s 10 GW solar manufacturing complex aims to establish a fully integrated photovoltaic value chain, from polysilicon and wafers to cells, modules, and solar glass.
High-purity argon is an essential shielding gas in crystal growth and other key processes, but it is costly in the local Indian market.
Lifengas’ argon recovery technology significantly reduces argon consumption and external dependence through closed-loop recycling, lowering operational costs while aligning with global low-carbon manufacturing trends.
With the cold box installation completed, the project is steadily progressing toward full operation.
Lifengas will continue to uphold professionalism and reliability, ensuring smooth execution of installation, commissioning, and start-up, creating long-term value for clients and supporting the sustainable development of the PV industry globally.
