On February 18, another key component of the purification unit in this department – the A-series cryogenic tanks for CO deep-cold separation – was successfully lifted, marking the entry of the cryogenic equipment used in this unit into the piping installation phase. The CO cryogenic separation Series A cryogenic tanks are the core equipment of the company’s CO cryogenic separation unit. They consist of 3 modules, with the tallest module reaching 35.66 meters in height and a total weight of 335 tons. Their installation was carried out in three stages, using a 400-ton crane for the main lifting operation and a 150-ton crane for assisting with the process. Before lifting the cold box, the project team held a special meeting to develop a specific lifting plan and safety measures, taking into account aspects such as foundation treatment at the lifting site and the angle of lift. The workers involved in the lifting operation were given detailed safety and technical instructions, outlining the construction procedures, risk points, key aspects, and challenges, thereby ensuring a comprehensive on-site arrangement with clear responsibilities assigned. After the lifting was completed, surveyors arrived to verify the position of the cryogenic tank to ensure that the installation location was accurate. As of February 18, the project team has completed the lifting of 50 out of the total 61 large-scale equipment units. Next, while continuing to complete the lifting work for large-scale equipment, the project team will further strengthen the supervision and management of equipment and steel structure installation, thereby creating a more favorable working environment for the installation of process pipelines and laying a solid foundation for the timely and smooth completion of the purification unit.
