In mid-May 2025, significant progress was achieved in the construction of the 15 million tons per year atmospheric and vacuum distillation unit, which is the key facility of the Huajin AAME fine chemicals and raw materials project; the convection sections of the two atmospheric heating furnaces, which are core equipment for this unit, were installed, and the main body of these heating furnaces has now been assembled. The 15 million tons per year atmospheric and vacuum distillation unit is the largest of its kind in China to employ two-stage vacuum deep drawing technology; it is responsible for the pretreatment and initial separation of crude oil to provide raw materials for further processing, and serves as the key unit of the entire project. The two atmospheric pressure furnaces were constructed using modular components; each furnace includes a radiation section, a convection section, and a waste heat recovery flue module. The convection section module installed this time is 30 meters long, 20 meters wide, and 18 meters high, with a total weight of over 840 tons. Since the project began, the company has employed construction methods such as factory-based prefabrication, modular construction, and prefabricated building to reduce the amount of on-site installation work as well as the number of workers and machinery required, thereby significantly improving the efficiency of on-site construction and reducing safety risks associated with work at heights. This time, it took only 4 days for the convection section to go from being delivered to the plant to completion of installation, with all construction work finished within that time.
