For Shandong Haitian Biochemical is was important to have the system installed quickly.

The largest soda ash production with Freelance was installed in record time

Shandong Haitian Biochemical Co. has undertaken a one-million-ton soda ash project in the Shandong province. It has an annual capacity of 400,000 tons of low-density soda ash, and 200,000 tons of light-density soda ash. Annual sales revenue is expected to reach 1.89 billion yuan.

As the largest application of Freelance in soda ash production, it took ABB ​only a month to install the system – the shortest work cycle for similar equipment.

The Freelance distributed control system is applied in eight work sections, namely salt water, lime, evaporation, decarbonation, compression, light ash, dense ash and packaging. The control room of each work section communicates with the central control room through a 10/100M fiber-optic loop network. The central control room is equipped with 14 pairs of redundant AC 800F controllers, one engineer station, 23 operator stations, and as many as 6,500 I/O points.
