A new polysulfide generation process was jointly developed by Mitsubishi paper mills, limited and Chiyoda corporation. The first system was installed at Mitsubishi paper's Shirakawa mill in 1987. The newest system was installed at Nippon paper's Ishinomaki mill and it has been successfully operated since September 1994.
The process can provide many advantages to conventional Kraft pulp mills, such as increasing pulp yield, reducing Kappa number, lowering the lime kiln load and reducing the boiler load. All of these benefits have been confirmed during mill operation.
