Recently, the National Energy Administration released the Compilation of Advanced Energy-Saving and Carbon Reduction Technologies in the Refining Industry, and the company's LQSR Energy-Saving Sulfur Recovery Tail Gas Treatment Technology was successfully included. 

Developed in collaboration with Qilu Petrochemical, Jiujiang Petrochemical, and other partners, the LQSR technology offers advantages including optimized processes, simplified controls, compact footprint, lower investment costs, and reduced energy consumption. It enables sulfur recovery rates to exceed 99.95%, reduces SO₂ emissions in exhaust gases to below 100 mg/Nm³, and achieves internationally leading performance metrics. The technology is widely applicable in petroleum refining, coal chemical industries, and related fields. 

First implemented in 2013 at Shandong Runze Chemical Co., Ltd.’s 55kta sulfur recovery unit, the technology passed a technical appraisal organized by Sinopec Group’s Ministry of Science and Technology in June 2017. To date, it has been successfully deployed in over 20 sulfur recovery units. 

Of the 14 advanced technologies selected in this compilation, 11 were contributed by Sinopec-related innovations.
