On July 3, at the construction site of the 500,000 tons per year methanol-to-ethanol production facility owned by Shaanxi Yanchang Petroleum Yulin Kaiyue Coal Chemical Co., Ltd., which is under the general contracting of Beijing Petrochemical Engineering Co., Ltd., the final section of the tower was accurately installed, allowing this 119.3-meter-tall and 747.38-ton heavy ethanol tower to be completed successfully. This marks a significant breakthrough in the development of this key provincial-level project. During the lifting process, in the face of challenges such as extremely high heights, large weights, and high precision requirements, the project team adopted a construction method of \"segmented manufacturing + assembly at height\", dividing the tower body into four segments for modular construction. From precision manufacturing to segmented transportation, from preprocessing such as dressing and covering to millimeter-level lifting and positioning, every step adheres strictly to various construction standards. This successful closure has acted as an accelerator for the overall construction of the project. At present, the detailed design of the project has been fully completed; the lifting of large-scale equipment is nearing its end. Key equipment such as the core reactor and heat exchangers have been installed one after another, and the installation of process pipelines is about to begin in full scale. This facility utilizes a domestically leading methanol carbonylation process; once operational, it will be able to convert 500,000 tons of methanol per year into ethanol products with high added value, thereby contributing significantly to the upgrading of the energy and chemical industry in Shaanxi Province. The site of Shaanxi Yanchang Petroleum Yulin Kaiyue Coal Chemical Co., Ltd.’s 500,000 tons per year methanol-to-ethanol production project is located on the industrial land reserved within Kaiyue Coal Chemical’s existing plant. The project utilizes the DMTE methanol-to-ethanol process technology developed by the Dalian Institute of Chemical Physics, Chinese Academy of Sciences; it involves upgrading the existing shift and purification units, and making use of the excess syngas and methanol available in those units for expansion and renovation. The project consists of four parts: a new factory complex, a vinyl acetate plant area, a circulating water pool area, and a reserved area. The total land area of the project is 53.9626 hectares, all of which are permanent land uses. The total investment amounts to 6.868 billion yuan, of which the estimated cost for soil and water conservation measures is around 107 million yuan. Construction contents: include a 200,000-ton/year ethyl acetate plant, a 250,000-ton/year ethanol-to-ethylene plant, a 250,000-ton/year vinyl acetate plant, and a 200,000-ton/year EVA plant, among others. The 250,000 tons/year vinyl acetate plant and associated auxiliary facilities were constructed in advance and put into operation. It will be constructed simultaneously with the Kaiyue Coal Chemical 500,000 tons/year methanol-to-ethanol project.
On June 20, a meeting was held to advance the 500,000 tons per year methanol-to-ethanol project of Shaanxi Yanchang Petroleum Yulin Kaiyue Coal Chemical Co., Ltd. At the meeting, the project construction command team made detailed and thorough arrangements for the construction schedule in the next phase. Each participating unit delivered a statement outlining how to achieve the goals and tasks of this campaign, as well as the specific measures to be taken, demonstrating firm confidence and determination to secure victory. Subsequently, the person in charge of the project construction command team and the representative of the general contractor solemnly signed the \"Target Responsibility Letter\" to clarify the responsibilities of all parties in line with the spirit of contracts, thereby providing a boost for the project’s development.

The ideal sequence of construction is: factory manufacturing – overall pressure testing – transportation to the site as a whole – installation of the surface elements – overall lifting, followed by the activation of the lights on the tower. It saves project duration, ensures quality, reduces safety risks, requires minimal space and time, improves work efficiency, and cuts costs.
