The chemical industry, with its intricate processes and precision requirements, constantly seeks ways to optimise and innovate. Anssum’s recent project in South Africa, titled “Dropleg Pulp Consistency Soft Sensor,” stands as a shining example of how technology can be harnessed to enhance operational efficiency in the chemical sector.

Project Overview

  • Category: Chemicals
  • Location: South Africa
  • Project: Dropleg Pulp Consistency Soft Sensor
  • Status: Ongoing since 01/07/2023


In the realm of pulp production, maintaining the right consistency is crucial. It affects not only the quality of the end product but also the efficiency and sustainability of the production process. Traditional methods of monitoring pulp consistency have their limitations, prompting the need for more advanced solutions.

The Challenge

  • Predicting the consistency of pulp at different stages of the bleaching plant with high accuracy.
  • Implementing a non-intrusive and efficient method of monitoring that can offer real-time insights and facilitate quick decision-making.

Anssum's Innovative Solution

In response to the challenges, Anssum introduced the “Dropleg Pulp Consistency Soft Sensor.” This state-of-the-art soft sensor was developed with the primary goal of predicting pulp consistency at various stages in the bleaching plant. The innovative aspects of this solution include:

  • Real-time Monitoring: The soft sensor provides immediate feedback on pulp consistency, enabling operators to make quick adjustments if needed.
  • High Accuracy: Emphasising the aspect of “Monitoring Accuracy,” the soft sensor ensures precise readings, reducing the margin of error and enhancing product quality.
  • Ease of Integration: Designed to seamlessly fit into existing systems, the soft sensor doesn’t require significant overhauls or changes in the plant’s operations.

Anticipated Outcomes

  • Improved Product Quality: With accurate consistency monitoring, the quality of the pulp produced is expected to be consistently high.
  • Operational Efficiency: Real-time insights mean less downtime, fewer errors, and a smoother production process.
  • Cost Savings: Precise monitoring can lead to reduced wastage and more efficient use of resources, translating to potential cost savings.
