On the eve of International Labor Day, the third section of the pre-separation tower, a key piece of equipment for the 500,000 tons per year methanol-to-ethanol production project owned by Shaanxi Yanchang Petroleum Yulin Kaiyue Coal Chemical Co., Ltd., which was contracted out through EPC by Beijing Petrochemical Engineering Co., Ltd., was successfully lifted into place. This marks the completion of the installation of the first tower unit in this project, laying a solid foundation for further construction work. As one of the core components of ethanol production facilities, the pre-separation tower utilizes 12 layers of packing to achieve precise separation of ethanol, methanol, and their azeotropes, thereby providing a crucial foundation for product purification and subsequent production processes. The tower has a diameter of 7.26 meters, a total height of 87.93 meters, and a total weight of 502.68 tons. It was transported in sections using a modular lifting method, with 3 sections delivered to the site in total. This lifting operation utilized a 1,250-ton class crawler crane and the \"single-machine lifting and delivery method,\" and it took 2 hours to align the components in the air; welding work was then carried out, with completion expected within 3 days. With the successful completion of the pre-separation tower, the construction of the ethanol plant will enter the full installation phase. Next, the project team will focus on advancing the installation of steel structures, the prefabrication of anti-corrosion treatments for process pipelines, and the monitoring of progress related to the overall design of the facility, in order to create favorable conditions for subsequent equipment installation and commissioning work.
