On March 25, BoHua Engineering's Party Secretary and Chairman, Zhan Hongzhi, led a delegation to attend the launch ceremony of the "Qingyang Tongxin 500,000 tons/year light hydrocarbon deep processing project 100-day攻坚competition activity" and conducted on-site supervision and inspection of the project progress and safety production work. Changqing Tongxin's Chairman and General Manager, Liu Hongtao, Deputy General Manager and Trade Union主席Wang Hong, Qingyang Tongxin's Chairman and General Manager, Wang Chunhui, as well as leaders from all participating construction units and project team members attended the event.

At the reactor manufacturing site, Zhan Hongzhi briefed the owner on the project progress. Currently, the civil engineering of the 150,000 tons/year maleic anhydride main unit has reached "±0," all individual units have commenced construction, steel structure installation has begun, underground pipeline construction is nearing completion, the welding pass rate has reached 100%, and the core equipment oxidizer for the maleic anhydride unit is planned to be manufactured by April 25, with installation scheduled for May 15. The owner expressed great satisfaction with the project quality and progress.

Wang Chunhui stated that the 500,000-ton/year light hydrocarbon deep processing project of Qingyang Tongxin is of great significance to the construction of an integrated energy and chemical industry base in eastern Longdong and the promotion of local socio-economic development in Qingyang City. Everyone should focus on three aspects: First, focus on the competition goal - "intensive work for 100 days, with foundations emerging from the ground", achieving the scheduled completion of the first and second batch of civil engineering foundations by May 30th and June 30th respectively. Second, focus on comprehensive management, coordinating, managing, and completing the six control objectives of this phase: "safety, quality, progress, investment, compliance, and integrity". Third, focus on the effectiveness of the activities.
On March 21, China Kunlun Engineering Co., Ltd. announced the tender for the construction general contracting of the 30,000 tons/year PBS unit in the 500,000 tons/year light hydrocarbon deep processing project in Qingyang Tongxin. The project is scheduled to start on April 25, 2025, and be handed over on December 30, 2025.
