en.Wedoany.com Reported - SPIC Aluminum Power Investment Co., Ltd., a subsidiary of China's State Power Investment Corporation (SPIC), has announced the launch of the Qingtongxia electrolytic cell "replace large with small" upgrade and renovation project at the Qingtongxia Industrial Park in Wuzhong City, Ningxia Hui Autonomous Region. The project, with a total investment exceeding 3.7 billion yuan, adopts the internationally leading 600kA ultra-large prebaked anode electrolytic cell technology, with a construction scale of 420,000 tonnes of electrolytic aluminum per year, aiming to replace and upgrade the existing outdated 200kA and 350kA electrolytic production capacity on-site. According to the project investment plan, it is scheduled to be completed and put into operation by 2027, at which point its technical equipment level and energy-saving and environmental protection indicators will achieve a leapfrog improvement.
SPIC Aluminum Power Investment Co., Ltd. is a wholly-owned secondary subsidiary of State Power Investment Corporation Limited, one of China's five major power generation groups. Headquartered in Yinchuan, Ningxia, its business covers the entire industrial chain including bauxite, alumina, electrolytic aluminum, electricity, and aluminum trade. According to the company's public data, it currently has an annual electrolytic aluminum production capacity of 990,000 tonnes and total assets exceeding 40 billion yuan. The main entities responsible for the construction and design of this project are consortia including China Minmetals Twenty-Third Metallurgical Construction Group Co., Ltd. and Shenyang Aluminum and Magnesium Engineering & Research Institute Co., Ltd., with a design contract amount of approximately 2.909 billion yuan.
This upgrade and renovation project will completely dismantle the existing 200kA (150,000 tonnes/year) and 350kA (270,000 tonnes/year) electrolytic series, totaling 420,000 tonnes of capacity, and build a new 600kA electrolytic series on the original site, installing 268 SY600 prebaked anode electrolytic cells, achieving "capacity reduction replacement and on-site upgrade." Upon completion, the new series will reach an advanced industry level in terms of comprehensive AC power consumption per tonne of aluminum and environmental emission indicators, and will integrate automation, informatization, and intelligent technologies to promote standardized safety management and intelligent energy control. At the project launch ceremony, Liu Fengyou, Party Secretary and Chairman of SPIC Aluminum Power Investment Co., Ltd., stated in his speech that the project is a key step in practicing the "dual carbon" goals and accelerating the development of new quality productive forces.
Public industry statistics show that the 600kA ultra-large capacity aluminum electrolytic cell technology, developed over many years by Shenyang Aluminum and Magnesium Engineering & Research Institute Co., Ltd. under Aluminum Corporation of China (Chalco), achieves a DC power consumption of 12,136 kWh per tonne of aluminum, ranking at the world-leading level. It is reported that this technology has previously been applied in major projects such as Xinjiang Nongliushi Aluminum Industry and Chalco Qinghai Branch. With the full implementation of the Qingtongxia project, it will effectively promote the green and intelligent upgrade of the electrolytic aluminum capacity structure in the Ningxia region.
