In today's era of green development, achieving both environmental protection and economic benefits has become a goal for many enterprises. LifenGas's BSLJ-JWHS Baoshan LONGi Methane Recovery Project stands as an exemplary case in this field.
On March 27, 2023, we officially signed the project contract to build a methane recovery unit with a processing capacity of 4000 Nm³/h. The system employs advanced PSA and TSA separation processes to transform waste tail gas from the deposition workshop into a valuable resource. The contract specified that the system should produce methane with ≥90% purity and maintain a yield of 80-93%, with a design condition for tail gas flow of 4000 Nm³/h (0°C, 101.325 KPa).
The project faced unexpected challenges during construction. We discovered the raw gas contained significant impurities—lubricating oil, benzene, liquid hydrocarbons, and water—which substantially differed from the working conditions originally provided by the client. LifenGas responded promptly, demonstrating strong professional capability and responsibility by signing a supplemental contract to add exhaust gas degreasing equipment and modify the existing degreasing system.
After intensive construction efforts, all project components were successfully completed on January 10, 2025. On February 20, the client notified us that conditions for commissioning had been met. At this stage, we found the actual flue gas flow was only 1300 Nm³/h, far below the design specification. Additionally, the installation of two sequential transformers significantly increased commissioning complexity. Nevertheless, our technical team persevered, applying their expertise and determination to overcome
these obstacles. On March 5, 2025, we successfully completed the methane recovery system commissioning.
.Once the unit achieved stable operation, both methane purity and yield exceeded design specifications. This success provides the client with high-quality, recyclable methane gas, effectively reducing production costs while achieving remarkable environmental benefits by reducing tail gas emissions
As the first methane recovery system of its kind in the country, this project demonstrates LifenGas' innovative strength and exceptional execution capabilities in environmental engineering, setting a new industry benchmark and contributing to green industrial development.
