Johan Christopher Fredrik Carl Richter (12 November 1901 – 13 June 1997) was a Norwegian-Swedish engineer, industrialist and inventor in the area of pulp and paper production. He developed the continuous processes for the digesting and bleaching of wood pulp used by his paper company Kamyr (now part of Andritz AG and Valmet). [1][2][3]

2020年10月1日 · The model was developed for simulation and control of a Kamyr digester by approximating series of continuously stirred-tank reactors (CSTR). In Smith’s model, it is assumed that there are three phases in the digester: solid wood, entrapped liquor and free liquor phase.

1996年6月1日 · Continuous Kamyr digesters play a pivotal role in the uniformity of product quality in pulp and paper mills. Chemical conversions and separations in the digester are controlled by regulating the Kappa number, a measure of residual lignin in cooked chips.

The Kamyr continuous pulp digester is a complex tubular reactor where wood chips react with an aqueous solution of sodium hydroxide and sodium sulfide (referred as white liquor) to remove the lignin from the cellulose fibers.

2018年2月28日 · The modified Kamyr continuous cooking (MCC) digester can be used to making paper pulp with lower Kappa value. Traditional Kamyr continuous digester makes higher lignin concentration of cooking liquor, which limits the delignification of wood chip.

Dynamic simulation with Mimic Simulation Software provides a high-performance solution for operator training and control system optimization. This Digital Twin technology delivers the complete environment for control system optimization and is an effective tool for teaching process and control engineers the control and operation of kamyr digesters.

Available from mid 2015 a complete Kamyr Digester system for continuous cooking of pulp. (Manufacturer: Ahltrom/Varkaus).
