【Ten Years of Rapid Development in Chemical Equipment】Acrylonitrile Reactor for 260,000 tons/year Acrylonitrile Project from 2019 to 2023

Thread Content

Ten years of rapid development in chemical technology; praise for the prosperous and strong China. This is just a starting point to encourage more participation from everyone. HaiChuan becomes even better with your involvement; we welcome all to join in the forum discussions. Be careful with fire risks as the heat increases in July. ---------------------------------------------- On July 2nd and 3rd, 2023, thanks to the joint efforts of all parties involved in the project, the two acrylonitrile reactors, which are key equipment for Sinochem Quanzhou Petrochemical’s 260,000 tons per year acrylonitrile production facility, were successfully installed. The equipment was designed by CNPC Jilin Chemical Engineering Co., Ltd. (referred to as Jilin Engineering), while CNPC Seventh Construction Co., Ltd. was responsible for its manufacturing, transportation, and installation. The equipment has a diameter of 9500 mm, a length of 32600 mm, and a wall thickness of 24 mm; its lifting weight is 291 tons. It presents manufacturing, transportation, and lifting challenges due to its large diameter, thin walls, and heavy weight. In order to achieve the delivery and lifting of the reactor as a complete unit, Project Department 1 of the Engineering Projects Center conducted technical evaluations a year ago in collaboration with Jilin Engineering regarding the delivery and lifting of the acrylonitrile reactor. A comparative analysis was carried out on aspects such as the manufacturer’s overall manufacturing capabilities, transportation conditions, lifting techniques and deformation control, as well as the impact on the installation of the reactor’s internal components; considerations related to safety, quality, schedule, and cost were also taken into account. Finite element analysis was performed on the stresses acting on key parts, and ultimately the feasibility of delivering and lifting the acrylonitrile reactor as a complete unit was confirmed, after which implementation began. Due to the oversized size of the equipment, it needs to be transported by sea to the Waizhoumadi roll-on/roll-off terminal and then moved to the project site; this involves various steps such as roll-on/roll-off transportation, sea transport, loading and unloading at the terminal for large items, and internal transportation to clear obstacles. On June 20, the reactors set sail from Shandong. After 10 days at sea, at 15:00 on June 30, the two reactors arrived safely at the heavy machinery dock.
