Let’s give a thumbs up and encouragement to the achievements made in China’s chemical technology and equipment sector. Your participation in the discussion serves as the greatest motivation! ********************** [Ten Years of Great Development in Chemical Equipment] This is a continuously updated summary thread; all are welcome to join the discussion: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** The first motor for China’s very first set of three electro-driven ethylene units has been successfully installed. On June 29, the first motor of the three-unit assembly for the ethylene plant under the second phase of Tarim’s 1.2 million-ton/year ethylene project—a project undertaken by our company—was successfully installed in one attempt. This marks a significant breakthrough for our company in ethylene plant technology, providing new impetus for the green development of the industry. The Tarim 1.2 million tons/year Phase II ethylene plant is the first facility in China to use motor-driven compressors for all three units involved in the production process – namely, the compressors for cracking gas, ethylene, and propylene. These three compressors are referred to as \"three units\" in terms of classification, but as \"four units\" when considering them as individual machines. This setup represents a practical implementation of the strategic decision to achieve the goals of carbon peak and carbon neutrality, as well as to promote high-quality development. By switching to motor-driven compressors, the electrification rate of the ethylene plant increased from 17.71% to 30.38%. Once completed, the plant will be powered entirely by green electricity, serving as a model for sustainable and low-carbon operations. Faced with challenges such as the technical gaps in China’s first ethylene plant equipped with three electric drives, complex installation processes, and extremely high precision requirements, lifting the first motor (weighing 63 tons and having a power output of 46,000 kilowatts) was a daunting task. The consortium formed by Beijing Company and Liu Jian Company faced the challenges head-on, overcoming the harsh conditions of extreme heat in the Xinjiang region. They conducted in-depth discussions on the lifting plan for the motors, focusing on the critical deadline of June 30th. With cranes scattered throughout the site, the installation of steel structures and process pipelines was carried out at full pace. Project leaders led several on-site inspections to carefully plan the routes for moving the motors and cranes. Party members and management personnel closely monitor every step and detail, working closely with the construction teams to ensure that all preparations for lifting are flawless. The most challenging moment during the lifting process is aligning and lowering the motor mounting hole with the fixing bolts. This process is extremely demanding; it is necessary to ensure that all 8 bolts are perfectly aligned before lowering them slowly into place. The deviation accuracy at each point must be kept within the millimeter range; even a slight deviation can result in all previous efforts being wasted. Faced with this challenge, all employees worked together with full focus. Leveraging their extensive experience and superb skills, they carried out a precise process of \"threading a needle,\" adjusting positions little by little. In the end, it only took 40 minutes to successfully align the foundation bolts of the motor. The motor sits firmly on its base, like a giant seated peacefully, signaling the successful completion of this crucial stage.
