Insisting on protecting the environment, we have invested a lot to introduce advanced acid regeneration facilities which can transform the HCL acid from pickling line of CRC production to a complete concentration of regenerated acid through a series of treatments such as high-temperature roasting. The regenerated acid can be reused and the by-products (ferric oxide) produced here can also be used as raw materials for other industries.
Its annual disposing capacity can reach 350 thousand cubic meters. 99% of the waste acid can transform into regenerated acid. Our acid regeneration system is an example of the cold-rolled coils industry to protect the environment.
