Environmental sustainability and efficient chemical processing are among the top priorities in today’s industrial sector. With a focus on these areas, Anssum embarked on an innovative initiative in South Africa, aiming to optimise Venturi Base Layer Control. This article delves into the project’s intricacies and its commendable contributions to improved pH control.

Project Overview

  • Focus Area: Chemicals & Environment
  • Country: South Africa
  • Description: Venturi Base Layer Control Optimisation
  • Status: Completed
  • Timeline: June 14, 2022 – July 15, 2022

The Challenge

In chemical processes, maintaining optimal pH levels is paramount. However, disturbances can affect this delicate balance, leading to inefficiencies and potential hazards. Responding proactively to these disturbances is essential to ensure safe and efficient operations.

The Anssum Solution

Recognising the need for advanced regulatory mechanisms, Anssum proposed the integration of a state-of-the-art controller designed to proactively counteract disturbances influencing pH control. The approach involved:

  • Time-Series Modeling: Utilising Fast Fourier Transform techniques, a time-series model was developed to understand the interplay between disturbances and the venturis.
  • Feedforward Design: Based on the insights from the model, feedforward elements were meticulously designed to enhance pH control in V5 and V6.

Technical Achievements

The outcomes of this initiative were notably significant:

  • Enhanced Stability: There was a marked 5% improvement in stability across V3, V5, and V6.
  • Reduced Deviation: The Mean Absolute Error (MAE) from the Set Point (SP) in V3, V5, and V6 was reduced by 3%, ensuring closer adherence to desired pH levels.

In Conclusion

Anssum’s Venturi Base Layer Control Optimisation project in South Africa exemplifies the company’s commitment to pushing the boundaries of chemical processing and environmental stewardship. By leveraging advanced techniques and a proactive approach, Anssum continues to drive excellence and innovation in the industry.

As global challenges in the chemical and environmental sectors intensify, Anssum remains at the forefront, championing solutions that address pressing needs and set new standards for the future.
