Highlights:
1、LifenGas has shipped the core cold box for a large-scale argon recovery system to India, marking a key milestone for RIL’s pioneering fully integrated solar silicon chip manufacturing project.
2、The system features a closed-loop design that recovers and repurifies argon with ≥97% efficiency, significantly cutting costs and promoting sustainable manufacturing for RIL's solar production.
3、This project represents a major international breakthrough for LifenGas's homegrown argon recovery technology, showcasing its competitiveness on the global stage.
4、The delivery of this key equipment paves the way for the project's next phases, supporting the broader development of India's solar industry with efficient, reliable technology.
The core cold box for the argon recovery system, designed and built by LifenGas for RIL’s solar silicon chip plant in India, has completed manufacturing and testing and is ready for shipment. This marks a key milestone in India’s fully integrated “quartz-to-module” photovoltaic value chain project.
Enabling Sustainable Manufacturing with Closed-Loop Innovation
RIL's 10GW solar manufacturing complex aims to establish a complete production chain from polysilicon and wafers to cells, modules, and solar glass. High-purity argon is essential in critical processes like crystal pulling, but argon’s cost is substantial in India. LifenGas's solution captures impurity-laden argon from the production line, purifies it, and returns it for reuse. This closed-loop system significantly reduces operational costs, lessens dependency on external supply, and supports a greener manufacturing model.
The system is designed for a capacity of 4,300 Nm³/h with an argon recovery rate of ≥97% at full load, representing industry-leading performance. The integrated process—from collection and compression to purification, drying, cryogenic distillation, and repressurization—ensures a reliable supply of high-purity argon back to RIL's production lines.
A Flagship Technology Reaches India Market
Argon recovery is LifenGas's foundational and core technology, pioneered and perfected in the Chinese market. This project with RIL signifies a major breakthrough in bringing this homegrown, innovative solution to a prestigious international client, showcasing LifenGas's growing competitiveness and brand influence in the global industrial gas processing sector.
Project Advances with Key Equipment Lead
With the cold box now en route, other core self-manufactured components like the dust removal and purification units are also ready for shipment to the Indian site. This phased delivery of major equipment lays a solid foundation for the subsequent construction and commissioning of the overall PV complex.
The successful execution of this project is not only a testament to LifenGas's capability to serve world-class enterprises and contribute to the global energy transition but also provides a viable and efficient "technology solution from China" for cost reduction and sustainable development in India's and the world's solar industry. LifenGas remains committed to ensuring the smooth implementation of the project's remaining phases, delivering long-term value to its partners and advancing the clean energy sector together.
