Resumen de Liaoning looks to lift standards in magnesia processing
Government incentives and academic cooperation have spawned a number of promising new environmentally sensitive projects in the capital of China's magnesia industry, Albert Li, IM Correspondent, finds.
Xinwei Environmental Protection Technology Co., a subsidiary of Chinese industrial conglomerate Fenghua Industrial Group based in Dashiqiao, Liaoning province, may have made a significant breakthrough in deadburned magnesia (DBM) production.
In June this year, the company produced its first DBM using environmentally-friendly, self-regulating digital technology. According to the company, it uses 20% less coal than traditional DBM production technology and yield is 20% higher, while direct emissions are practically zero.
Xinwei's project was part of the first batch of projects to be funded by China's Ministry of Science and Technology under the country's 12th five-year plan for 2010-2015. Its technology took five years to develop, with the help of engineers from Liaoning University of Technology, Northeastern University, Wuhan University of Technology and Beijing University.
Xinwei and its partners have constructed a prototype production line, with four large standing kilns, each with a DBM capacity of 80,000 tpa. The production line cost Chinese renminbi (Rmb) 97m ($14.4m*) to build, but its output is expected to have a market value of Rmb 300m ($44.6m).
Although Xinwei Environmental Protection Technology Co. has worked to produce DBM using less coal than traditional production, other companies in the area are still producing large amounts of air pollution, as demonstrated in the above image, taken during a visit to a suburb of Dashiqiao.
