Common Selection Mistakes and Risks

Product Grade Compliance Risks

Selecting a product grade that does not match the requirements of the intended application may result in non-compliance with customer, industry, or regulatory expectations.

This can create difficulties during audits, certification processes, product approvals, and commercial sales activities.

Therefore, procurement, quality, and technical teams typically confirm that the product grade aligns with the specific requirements of the intended application before use.

Inconsistent Production Results

Differences in product characteristics between deliveries may influence recipe repeatability, process consistency, and the predictability of production outcomes.

This can lead to additional process adjustments, increased quality control requirements, and higher operational costs.

Therefore, technologists and production teams typically assess batch-to-batch consistency and supplier reliability as part of product evaluation.

Variations in Reaction Rate

In applications where the product is used as a source of CO₂ or as a process reagent, physical characteristics can influence reaction performance and process behaviour.

This can affect production results and may require additional process adjustments.

Experts consider the specific requirements of the intended application.

Challenges in Automated Dosing

Unsuitable physical characteristics can affect mixing performance and the uniform distribution of the product within the process.

This increases the risk of process deviations and inconsistent production results.

Experts evaluate the compatibility of the product with the intended dosing technology.

Hidden Costs of Low-Cost Product Selection

Selecting a product based solely on purchase price may overlook factors that influence process performance, consistency, and overall operational efficiency.

This can lead to additional process adjustments, increased quality control efforts, production variability, and higher total operating costs.

Therefore, technologists, production teams, and procurement specialists assess the total process impact of a product rather than comparing price alone.

Typical Production Challenges

Inconsistent CO₂ Release

Variations in process conditions can affect the rate and completeness of carbon dioxide release during production.

This makes it more difficult to achieve consistent results across production batches.

Uncontrolled Dough Rise

In bakery and confectionery applications, inconsistent gas generation can affect the structure, volume, and overall quality of finished products.

This increases the risk of product defects and non-conformance with product specifications.

Loss of Buffering Capacity

Insufficient control of acidity can affect the stability of production processes and formulations.

This increases the risk of quality deviations and may require additional process adjustments.

Instability of Acid-Base Balance in Feed Formulations

In feed applications, variations in buffering performance can affect feeding efficiency and the consistency of feed formulations.

This makes it more difficult to achieve predictable production outcomes.

Insufficient Efficiency of Dry Acid Gas Neutralisation (DSI)

In emission control systems, reaction efficiency depends on the correct selection and dosing of the reagent.

This increases the risk of excessive reagent consumption and failure to achieve target emission control performance.

Excessive Reagent Consumption in DSI Systems

Incorrect product selection or unsuitable dosing parameters can increase the actual consumption of sodium bicarbonate in dry sorbent injection (DSI) systems.

This increases reagent costs and reduces the overall cost-effectiveness of the flue gas treatment process.

How the Product Supports the Process

Control of Finished Product Structure

Sodium bicarbonate helps control gas formation during processing and contributes to the development of the desired product structure.

This helps achieve the required porosity, volume, and consistency of finished product characteristics.

Stable Acid-Base Balance

The buffering properties of sodium bicarbonate help reduce rapid pH fluctuations in process systems and production environments.

This contributes to greater process stability and improved consistency of formulations and production outcomes.

Consistent Process Reactions

Stable product characteristics help maintain predictable reaction conditions and support consistent performance across production batches.

This reduces process variability, minimises the need for operational adjustments, and helps ensure repeatable production results.

Consistency of Feed Formulations

In feed applications, sodium bicarbonate is used to help maintain the required acid-base balance of feed formulations.

This helps ensure consistent characteristics of finished feed products from batch to batch.

Control of Flue Gas Treatment

In dry flue gas treatment systems, sodium bicarbonate reacts with acidic components and helps facilitate their removal.

This helps achieve target emission control performance while maintaining controlled reagent consumption.

Typical Industrial Applications

Economics of Product Selection

Stoichiometric ratio = actual sorbent consumption / theoretical sorbent requirement.

In dry flue gas treatment systems, this ratio indicates the amount of sodium bicarbonate applied relative to the theoretical requirement for acid gas neutralisation.

Process performance depends on particle size, milling efficiency, gas temperature and contact time between the sorbent and the gas stream.

In food applications, performance is determined by the balance between sodium bicarbonate and the acidic components within the formulation.

Key process indicators:

• stoichiometric ratio;
• HCl and SO₂ removal efficiency;
• residual reagent in residues;
• residue generation after gas treatment;
• product pH;
• CO₂ generation;
• final product structure.
