ADVANCING PH CONTROL

VENTURI BASE LAYER CONTROL OPTIMISATION IN SOUTH AFRICA

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.“

SRP OPTIMISATION

STREAMLINING CHEMICAL USE FOR A GREENER SOUTH AFRICA

In the realm of chemical engineering and environmental conservation, the judicious use of raw materials is paramount. Anssum, in its pursuit of sustainable solutions, undertook an initiative in South Africa to optimise Slurry Response Processes (SRP). Let’s delve into the intricacies of this project and its commendable outcomes.

Project Overview

  • Focus Area: Chemicals & Environment
  • Country: South Africa
  • Description: SRP Optimisation
  • Status: Completed
  • Timeline: July 24, 2021 – August 4, 2021

The Objective

The primary challenge in many chemical processes is the efficient and precise control of pH levels. Mismanagement can lead to overutilisation of raw materials, resulting in increased costs and potential environmental hazards. Moreover, smoother slurry responses are essential for reducing slurry usage, which has direct implications for both cost and the environment.

The Anssum Approach

With the above challenges in mind, the SRP optimisation initiative was rolled out. The project focused on two main goals:

  • Achieving tighter control of pH levels using fewer raw materials.
  • Ensuring smoother slurry responses, leading to reduced slurry usage.

Using advanced monitoring tools and innovative process controls, Anssum was able to fine-tune the chemical reactions involved, ensuring minimal wastage and optimal results.

Technical Outcomes

The results of this initiative were both immediate and impactful:

  • Stability Enhancement: The processes became more stable, ensuring consistent and reliable results.
  • Reduced Raw Material Consumption: With the tighter control of pH levels, the use of raw materials significantly decreased.
  • Environmental Benefits: A direct consequence of using fewer raw materials was the reduction in emissions, further underlining Anssum’s commitment to environmental conservation.

Conclusion

Anssum’s SRP optimisation project in South Africa stands as a testament to the company’s dedication to sustainable chemical engineering practices. Through innovative techniques and a deep understanding of the processes involved, the project not only achieved its goals but also set a benchmark for future initiatives.

“In an era where sustainable practices are more crucial than ever, Anssum’s endeavors highlight the symbiotic relationship between industry and environment. As we continue our journey, projects like these pave the way for a more sustainable and eco-friendly future.“
