IoT Based Pulp Quality Enhancement Through Bleaching Process in ECF Plant

The Addition of Hydrogen Peroxide (H

O

) in ECF (Elemental Chlorine Free) plant during Extraction of Pulp stage in SPB Ltd was conventionally done manually by measuring the flow of pulp, Temperature, pH of respective pulp processing mixer tanks, which results in uneven mixing of H

and pulp thereby decreasing the brightness and production quality of the paper. To automate the Bleaching process of chemical pulping by addition of Hydrogen Peroxide into the mixer by Variable frequency driver where by inferring the Flow of Pulp, Temperature and pH of the Mixer and the amount of Pulp Bleached should be monitored through a IoT cloud. The Motto is to atomize the Conventional Addition of Hydrogen Peroxide in ECF (Elemental Chlorine Free) plant of SPB Ltd using Variable Frequency Driver and to monitor the flow of Pulp through IoT cloud. The correct addition of Hydrogen peroxide will also improve the Replacement ratio, effectiveness of chelating wash and oxygen delignification.
