The 1.2 mt/s ethylene plant at Guangxi Petrochemical, for which Huanqiu Company provided core proprietary technology and served as the EPC general contractor, has successfully completed a 96-hour performance test, with core equipment such as the triple-unit operating stably.
The Guangxi Petrochemical 1.2 mt/s ethylene plant achieved a successful one-time feedstock startup in October 2025 and completed performance testing in late December. The test results show that the produced polymer-grade ethylene, propylene, and other products exceed the national standard premium grade requirements and can reliably support downstream production of high-end chemical new materials. Core yield and environmental indicators are excellent, and the key equipment operated smoothly throughout without abnormal fluctuations. The plant adopts a front-end demethanization front-end hydrogenation separation process, which offers the dual advantages of simplified flow and low ethylene loss. The commissioning of the world’s first large-scale electrically driven ethylene refrigeration compressor, which replaces traditional steam turbines with high-efficiency direct-drive motors, significantly improves energy efficiency and reduces carbon emissions.
