On January 1, 2026, the EPC project for the 4×1000kt sulfuric acid production units that are part of the KNI plant with an annual nickel production capacity of 120,000 tons – a project undertaken by China National Chemical Engineering Sixth Construction Corporation’s Indonesian branch – reached an important milestone: the first piece of equipment was successfully lifted, marking the official start of the equipment installation work for this project. On this New Year’s Day, the overseas project team of LiuHuaJian remained at the work site with a determination to go all out from the start. Under careful organization and precise guidance, they successfully completed the installation of the two exhaust gas absorption towers for Series 1 and 2 of the acid production facility in just 4 hours, in a safe and efficient manner. Each unit of this equipment weighs 45 tons, has a diameter of 6 meters, and a height of 25.7 meters. The installation was carried out using a combined lifting method involving a 150-ton crawler crane for the main lifting task and an 80-ton truck crane for assisting with the lifting process; this approach ensured safe and smooth execution of the lifting operations. Once completed, this sulfur-based sulfuric acid production facility will supply raw materials in a stable manner to the downstream high-pressure acid leaching smelting system, which is of great significance for ensuring the operation of the entire project and promoting the development of the local new energy battery material industry in Indonesia.
