Carbonatation Station Operation And Control Training

SAQA US 114327 | NQF 2 | Credits 8 | Duration 5 Days
From $1,242 per delegate

Description

This course equips learners with the knowledge and skills to operate and control a carbonatation station effectively and safely. It covers the principles of carbonatation, process control parameters, and troubleshooting techniques to ensure optimal performance in sugar processing.

Learning Outcomes

  • Demonstrate the ability to start up, operate, and shut down a carbonatation station according to standard operating procedures.
  • Monitor and control key process parameters such as juice flow, lime addition, and carbon dioxide dosage to achieve optimal carbonatation.
  • Analyze process data and identify deviations to implement corrective actions for maintaining product quality.
  • Apply safety protocols and hazard identification techniques to ensure a safe working environment.
  • Evaluate the efficiency of the carbonatation process and recommend improvements.
  • Interpret and apply relevant standard operating procedures and quality specifications.

Target Audience

This course is designed for process operators, shift supervisors, and technical personnel involved in the operation and control of carbonatation stations in the sugar industry.

Prerequisites

None — open enrollment.

Course Outline

Day 1: Introduction to Carbonatation and Plant Overview

Objectives:
• Understand the role of carbonatation in sugar processing.\n• Identify key equipment and flow paths in the carbonatation station.\n• Explain the chemical principles of carbonatation reactions.\n• Describe safety protocols and personal protective equipment requirements.

Topics:
• Overview of the sugar manufacturing process and carbonatation's position.\n• Chemistry of carbonatation: lime addition, carbon dioxide absorption, calcium carbonate precipitation.\n• Main equipment: carbonatation tanks, lime slakers, carbon dioxide supply systems.\n• Process flow: juice heating, liming, carbonation, filtration.\n• Safety hazards: chemical handling, confined spaces, high temperatures.\n• Personal protective equipment and emergency procedures.

Day 2: Process Control Parameters and Instrumentation

Objectives:
• Identify critical control parameters: pH, temperature, flow rates, and pressure.\n• Explain how pH and temperature affect carbonatation efficiency.\n• Operate and interpret readings from common instrumentation.\n• Adjust control loops to maintain optimal conditions.

Topics:
• Key parameters: juice pH (target 8.5-9.5), temperature (80-85°C), CO2 flow rate.\n• Instrumentation: pH meters, thermocouples, flow meters, pressure transmitters.\n• Control loops: PID controllers for pH and temperature.\n• Effect of deviations: under-liming, over-liming, scaling.\n• Calibration and maintenance of sensors.\n• Data logging and trend analysis.

Day 3: Operational Procedures and Troubleshooting

Objectives:
• Execute standard start-up and shut-down procedures.\n• Monitor and adjust lime slurry concentration and CO2 dosage.\n• Diagnose common operational issues such as scaling, foaming, and poor filtration.\n• Implement corrective actions to restore process stability.

Topics:
• Start-up sequence: preheating, lime preparation, CO2 supply.\n• Normal operation: maintaining pH and temperature setpoints.\n• Troubleshooting: scaling in tanks and pipes, foaming causes and control, filterability problems.\n• Lime slurry quality: milk of lime density and grit content.\n• CO2 purity and flow control.\n• Shut-down procedures: draining, cleaning, inspection.

Day 4: Quality Control, Sampling, and Analysis

Objectives:
• Perform sampling and on-site analysis of juice and carbonatation products.\n• Interpret analytical results to assess process performance.\n• Relate juice clarity, colour, and purity to carbonatation efficiency.\n• Document and report quality data according to standards.

Topics:
• Sampling points: raw juice, limed juice, carbonated juice, filtrate.\n• Analytical tests: pH titration, alkalinity, calcium hardness, turbidity, colour.\n• Interpretation: optimal ranges for juice clarity and colour removal.\n• Impact of carbonatation on downstream processes (evaporation, crystallization).\n• Record keeping and reporting formats.\n• Corrective actions based on analysis.

Day 5: Advanced Control Strategies, Optimization, and Integration

Objectives:
• Apply advanced control strategies (cascade, feedforward) for enhanced stability.\n• Optimise lime and CO2 consumption for cost efficiency.\n• Integrate carbonatation station operation with upstream and downstream units.\n• Conduct a simulated process improvement exercise.

Topics:
• Advanced control: cascade control for pH, feedforward for juice flow changes.\n• Optimisation: minimising lime and CO2 usage while meeting quality targets.\n• Integration: coordination with juice heating, clarification, and filtration.\n• Energy efficiency: heat recovery and steam usage.\n• Simulated scenario: adjusting parameters to improve throughput.\n• Review of key performance indicators and continuous improvement.

Practicals

No practicals for this training.

This course is made up of exercises and case studies delivered alongside the theory — no separate practical sessions are required to complete it.

Summatives

Each delegate is assessed continuously throughout the course and a final summative test at the end.

Daily Exercises — 30%

Every training day ends with a multiple-choice exercise scored out of 100%. The scores from each daily exercise are averaged across the duration of the course to produce a Daily Average mark, which contributes 30% to the final total.

Final Test — 70%

On the last day a final summative test is written. It is a multiple-choice paper with multiple-answer questions: each question may have more than one correct option, and a single wrong selection on a question marks the entire question wrong — no partial credit. The final test is scored out of 100% and contributes 70% to the overall mark.

Final Total

All marks are recorded on the AATICD LMS and visible to each learner under their account.

Certificate

Certificate of Completion

Awarded to delegates who achieve an overall mark of 50% or higher on the Final Total (Daily Average 30% + Final Test 70%).

How it works
  • Certificates are auto-generated on the AATICD LMS as soon as the marks pass the 50% threshold.
  • Each certificate is a branded PDF with the delegate's name, the course title, the unit standard ID, NQF level, credits, and the date of issue.
  • You can download or print your certificate from your LMS dashboard at any time after issue — there's no reissue fee and no expiry date.
  • If you scored under 50% you can sit the final test again at the next scheduled session at no extra cost.
Where to find it

Sign in to the LMS, open your dashboard, and your certificates appear under My Certificates. Each entry has a View / Download button and a print option.
