At 14:50 on August 3, good news came from the start-up headquarters of the Changqing ethane to ethylene project of PetroChina Lanzhou Petrochemical Company. The 800,000 tons/year ethylene unit was put into operation on August 2. After nearly 28 hours of production and operation, qualified ethylene products were produced. This marks that the Changqing ethane to ethylene project, with the joint efforts of Lanzhou Petrochemical Company and all participating units, has successfully achieved the planned node goals and achieved a successful start-up after two years of arduous efforts. This is the first ethane cracking to ethylene project in China, which has a demonstrative role. It is the eldest son of the Republic, a new project with a new journey and a new youth. A modern chemical factory stands on the desert sands of the Gobi Desert, a dream-chasing journey for petrochemical people in the new era. The utilization of domestic light hydrocarbon resources has achieved new results. The era of low-cost polyolefin competition is here. On July 30, the full-density polyethylene unit of the Yulin Ethylene Project entered intense testing, and the circulating air compressor of the key unit of the unit was working normally. On July 29, the extrusion pelletizer, the core equipment of the high-density polyethylene unit of the Changqing ethane-to-ethylene project constructed by Huanqiu Jilin Chemical Construction, went through the mixer feeding and flushing, and the template belt flushing, and finally entered the extrusion pelletizer to produce qualified products. The first feeding test was successful. Since the delivery of the device on June 26, in accordance with the progress of the feeding node, the project department has concentrated on carrying out air sealing of process pipelines and equipment feeding and commissioning, sounding the clarion call to comprehensively win the project feeding and production battle. Recently, the stand-alone test run and instrument chain experiment of the main motor of the extruder unit, PCW pellet water flushing system, lubricating oil system, hydraulic oil system, and hot oil system were all completed as planned. Through the joint efforts of the project department and the operation team, the extruder produced qualified polyethylene pellets on July 29. As early as July 4, the last imported equipment of Lanzhou Petrochemical's Changqing ethane-to-ethylene project arrived safely at the site, six days earlier than required by the group company, ensuring the commissioning of the device. The circulating gas compressor turbine of the full-density polyethylene plant is the first imported special model customized by a foreign manufacturer based on the device process. It is the key equipment for the smooth start-up of the full-density polyethylene plant of the Changqing ethane-to-ethylene project. If the equipment arrives at the site one day earlier, it will gain an extra day of valuable installation and commissioning time for the device to start up. The ethane-to-ethylene plant whose raw material comes from natural gas is of great significance and serves as a demonstration for the transformation of my country's basic chemical raw material pattern into a green and low-carbon one. It has lower costs, lower energy consumption, and less carbon emissions for the utilization of natural gas resources. * * Promote the carbon neutralization process of the chemical industry.
