On May 24, the chemical plant ground flare project as part of the Guangxi Petrochemical integration and transformation project, which was constructed by CPECC’s First Construction Company, was completed to high standards. It is stated that the chemical plant floor flare system is primarily used to handle flammable emissions from various process units during emergencies such as startup/shutdown, power outages, water outages, or operational failures, as well as those from related storage and transportation facilities. This project marks the first time that China National Petroleum Corporation has adopted open-air flare stacks for all its chemical processing units, comprising 3 sets with 5 systems in total. Aiming to create a model project that is safe and efficient, the Public Works Project Department of Guangxi Petrochemical completed the construction tasks with high quality over a period of 6 months. At the same time, a flexible and efficient coordination mechanism of \"daily reviews and weekly scheduling\" was established to optimize construction procedures and strengthen process control. In total, 1,275 foundation construction processes for civil engineering ducts and 258 foundation construction processes for windbreak walls were optimized, enabling the completion of the civil engineering tasks 15 days ahead of schedule through a two-shift system. In terms of quality control, the project team uses the DingTalk platform to create an inspection database, uploading data daily and issuing corrective action instructions. The installation of the embedded components at the top of the pipe supports under the torch pipeline adopts a dual-fixing technique of \"reinforcement framework + formwork\". The elevation of these embedded components is checked multiple times, and the spacing is controlled using edge-cutting and equal division methods along with specialized gauges, to ensure that the deviation of the embedded steel plates from the horizontal plane remains within 2 millimeters ； Welding was carried out on completely different steel materials; special process cards were prepared along with ongoing spectral testing. 310 sets of pressure testing fixtures were manufactured, and leakage tests were conducted on 1,774 burners, with a 100% pass rate for the critical processes at the first attempt. In light of the actual conditions of the project, the project department implemented a \"three-level grid-based, localized\" management system, designated 6 major responsibility areas, and equipped 450 ice cream cones to mark warning zones. For hazardous tasks such as pressure testing, risk analysis meetings were held and energy isolation plans were developed; a total of 1.04 million safe working hours were achieved, thus fulfilling the safety commitment with zero accidents. Next, the project team will fully cooperate with the efforts to ensure operational continuity, so as to guarantee that the facility can start up, operate stably, and maintain operation over a long period of time.
