Installation of the Methanol Atmospheric Distillation Tower for the Industrial Gas Island & Syngas Comprehensive Utilization Project at Guangxi Huayi Energy Chemical Co., Ltd. Author/Source: HuaHua Network – Coal Chemicals Date: 2020-08-19 Clicks: 11 At 11:18 a.m. on August 15, with the installation of the No. 2 methanol atmospheric distillation tower for the methanol unit of the Industrial Gas Island & Syngas Comprehensive Utilization Project at Guangxi Huayi Energy Chemical Co., Ltd., which is under the general contracting of China Chengda Engineering Co., Ltd. (hereinafter referred to as “China Chengda”), the second batch of 22 large-scale equipment at the site was successfully installed, marking the completion of this phase of construction. The successful completion of the 20-day intensive lifting operation marked the finish of the lifting of the project’s large-scale equipment, finishing 7 days ahead of the original schedule and contributing significantly to the \"Double Hundred Campaign to Combat the Pandemic and Ensure Revenue.\" 2# Methanol atmospheric distillation tower lifting site. The Guangxi Huayi project is a key initiative in the Qinzhou Port Economic Development Zone in Qinzhou City, Guangxi Zhuang Autonomous Region. Located in a strategic position, it is the only free-trade port along China’s western coast. It represents the shortest route from the Chinese mainland to Southeast Asia, Africa, Europe, and Oceania, serving as a vital channel for goods from southwestern and southern China to be exported overseas. Once completed, this project will play a crucial role in the development of the Qinzhou Port Economic Development Zone. It also provides a foundation for the project owner to advance the upgrading and structural adjustment of the traditional coal chemical industry, thereby fostering green, circular, and low-carbon development. This round of lifting operations for large-scale equipment is an important part of the methanol plant construction process; it involves many management details and presents significant technical challenges. Most of the equipment needs to be transported to the port and loaded onto ships, before being shipped by sea to the unloading dock in Qinzhou. Some special equipment even requires sea vessels to transfer it to barges, which then carry it to the unloading dock; only after a series of complicated and meticulous tasks such as on-site transportation, unloading, and preparation can it finally be successfully lifted into place. At the site of the 1# methanol vacuum distillation tower installation, as planned, 22 pieces of equipment along with the towers and heat exchangers in the methanol area are to be installed simultaneously, a process that will take at least 27 days. If this is not completed on time, the cranes will have to be allocated to other installations, which will delay the progress of this round of heavy equipment installation work. To ensure the progress of the lifting operations, the project team carried out thorough planning: all the large tower equipment was arranged in a \"U\" shape around the distillation framework. This arrangement not only saved space and did not interfere with the work of other teams, but also ensured continuity in the lifting operations. At the site, 750t and 400t cranes were used as the main lifting equipment; the 750t crane operated from south to north while the 400t crane worked from north to south, lifting simultaneously. A 280t trailing crane moved back and forth between them. This approach greatly reduced the required lifting space and time. Lifting 22 large-scale equipment units in 20 days means lifting one such unit per day; such an intensive and continuous lifting schedule requires that no mistakes occur at any stage. The on-site project team requires that all personnel must take things seriously, with dedicated staff providing specialized support to the project subcontractors, ensuring that everything is tracked and assistance is available at all times. It’s bustling during the day and brightly lit at night; the shipping and arrival times for each piece of equipment are highly precise, and the basic deviations of each device are strictly kept within specified limits. The installation of eight large towers for 1#/2# methanol has been completed. Starting from the 17th of this month, the Guangxi Huayi Methanol project will officially enter its next phase of work. Through relentless efforts and a commitment to excellence, China Chengda will continue to achieve one milestone after another with high quality, delivering satisfactory and top-notch projects to its clients. The Huayi Qinzhou Chemical New Materials Integrated Base project is located in the Qinzhou Petrochemical Industrial Park, covering an area of about 8,000 mu, with a total investment of around 70 billion yuan. It will be implemented in three phases. It covers four major industrial chains: coal chemical industry, light hydrocarbon cracking, salt chemical industry, and downstream petrochemical industry, involving 40 types of chemical products and 65 sets of processing units. One of these industrial gas island projects involves an investment of 14.3 billion yuan; it is part of the coal chemical industry chain. Construction began in November 2017, with the aim of producing industrial gases such as hydrogen, syngas, and nitrogen for use by enterprises within the park, as well as chemical products like methanol, ethylene glycol, and acetic acid. Completion and operation are expected by 2020. The second-phase light hydrocarbon comprehensive utilization project has a total investment of around 20.8 billion yuan. With ethane cracking and propane dehydrogenation as its core processes, the project will produce products such as polyethylene, ethylene glycol, ethylene-vinyl acetate copolymer (EVA), acrylates, polyether polyols, caustic soda, and polyvinyl chloride. Construction is expected to begin in 2019. The main plant area of the project is located in plots 25 and 26 in the Qinzhou Petrochemical Industrial Park, to the south of it. The third-phase methanol-to-olefins and downstream processing project has a total investment of around 18.3 billion yuan; it will produce products such as polypropylene, polycarbonate, polymethyl methacrylate, caustic soda, and polyvinyl chloride, with construction expected to begin in 2025.
