The spring breeze brings good news! On March 29, as the liquid level in the ethylene storage tank rose to the designated height and all relevant indicators met the design requirements with high quality, the plant operated smoothly. The second low-temperature ethylene unit of Lianyungang Rongtai successfully started up on its first attempt, marking yet another significant achievement for China Air Separation in its deep cultivation of the low-temperature storage tank sector, its efforts to build a green energy system, and its contribution to the development of the petrochemical industry in Lianyungang!
Since entering the preparation phase for feed-in and commissioning, China Air Separation has made meticulous arrangements and mobilized its best personnel, forming a team responsible for startup command and operations. This team has conducted thorough inspections of all on-site pipelines, flanges, valves, equipment, and instruments, while also working closely with the manufacturer to carry out rigorous adjustments and tests on key equipment such as compressors.
On the morning of March 23, the real-gas replacement work for the second low-temperature ethylene unit officially kicked off, marking the full-scale start of the unit’s commissioning. To ensure real-time monitoring of every step of the progress, project team members implemented a 24-hour, round-the-clock shift system between the site and the central control room. Party members within the branch took the lead, stepping forward with determination. Each shift handover was like passing a relay baton—every “Let me take over” not only conveyed a sense of responsibility and commitment but also echoed the rallying cry: “I’m a Party member; I’ll go first!” As a result, the Party flag flew high at the project’s frontline. Finally, early on the morning of the 29th, the liquid-level gauge on the ethylene storage tank in the central control room showed a clear liquid level. This milestone signified that after years of steadfast dedication and relentless efforts, the project team had finally achieved the long-awaited success, smoothly transitioning from construction and installation to a new phase of production and operation.
This successful commissioning once again underscores China Air Separation’s commitment to delivering high-quality projects that benefit society. China Air Separation will continue to shoulder the responsibilities of a central state-owned enterprise, relentlessly deepen technological innovation, and consistently develop core technologies. We will apply our technological achievements to project construction, strengthen, optimize, and expand low-temperature petrochemical storage projects, accelerate the development of new-quality productivity, and contribute our expertise to supporting the implementation of national strategies!
