Super Batch Cooking Production Line

Super Batch Cooking Production Line for Paper Pulp Cooking

In 2007, basing on the characteristics of conventional cooking, our company developed a 300,000t of annual output of super batch cooking production line that adopts an efficient pulping technology with making use of new energy on the basis of conventional cooking technology, which can save about 60% of cooking steam consumption that is roughly equivalent to the reduction of 10,000t annual coal consumption (Standard coal as measurement unit). Meanwhile, we can reduce by about 15% of SO2 emission (sulfur dioxide) and soot aggregates from the alkali recovery boiler, achieving zero emission wastewater and reducing the emission of bleaching wastewater. According to different raw materials, the technology can be also applied to produce dissolving pulp.

 

Advantages of super batch cooking technology

  • Compared to conventional cooking steam consumption, our equipments can achieve great reduction of that. Our super batch cooking technology can reduce to 0.6-0.8 ton of steam consumption from 2-2.5ton for producing 1 ton paper pulp.
  • Oxygen delignification; Low Kappa value; High strength of paper.
  • Pulp has excellent bleaching properties for the reasons of low Kappa value, high strength, oxygen delignification and good production conditions. Meanwhile, relevant chemical consumption drops down, which not only reduces environmental pollution, but also lowers paper cost.
  • The whole production process is fully under automatic control, and then the system reliability is greatly improved, and therefore pulp quality is stable and reliable.
