null Sulphite process paper

Sulphite process paper

The sulphite process is an industrial process to produce wood pulp suitable for wood low in resin and silicic acid.The advantages of this process are above all the very efficient delignification, the good bleachability, the high reactivity during further processing and low investment costs. In the sulphite process, the wood fibres are digested in an acidic or neutral medium. In the process, the lignin is subjected to sulphonation and is thereby converted into a water-soluble salt which can be removed from the cellulose. The by-product lignosulphonates are either commercially recovered or incinerated (recovery). In case of recovery the black liquor separated from the fibres during pulp washing is evaporated and burned in the recovery boiler using oxygen. The very light pulps produced in this way are today used almost exclusively for the production of chemical cellulose or paper. To produce one tonne of pulp you need about five cubic metres of wood and 90 kilograms of sulphur.

Production rates increase while product quality improves

GAS APPLICATION

In the case of nitrogen-steam systems, the process parameters can be set individually. The steam provides the heat, and the nitrogen stabilizes the pressure to the desired level. As a result, nitrogen-steam systems have a shorter cycle time. In addition, the production rates increase while at the same time product quality improves, since local overheating of the steam is avoided. This protects the bladder and the rubber.
