AutoBlend System - Dilution of Chemicals
In the finishing industry, the various chemicals are often not used in the maximum possible concentrations. However, transport and storage costs ususally drop when the concentration increases, since the share of water needs to be neither transported nor stored.
Chemical Dilution in the Finishing Industry
Cost-Saving Benefits of Concentrated Chemicals
In finishing processes, chemicals are often diluted for use, but transporting concentrated forms reduces logistics costs. Automatic diluting stations make it feasible to switch to higher concentration inputs for better ROI.
Applications for Common Chemicals
Diluting stations are compatible with caustic soda, potash lye, peroxide, sulphuric acid, and more—assembled easily using metering pump systems.
Example: Continuous Dilution of 96% Sulphuric Acid
System Components
- Storage container for H₂SO₄
- Screw feeder to transfer powder
- Water tank with float valve control
- PTFE-lined mixing air vessel with non-return valves
- Two-component metering pump
Safety and Temperature Management
- Automatic shut-off valve prevents backflow during shutdowns
- Relief valves for both liquid phases
- Impregnated graphite cooler reduces diluted acid temperature below 40°C
- Cooling water flow regulated based on acid temperature
- Independent temperature limit switch safeguards against overheating
Advantages of Inline Dilution Systems
The compact design eliminates the need for separate mixing vessels and minimizes wait time compared to batch operations—delivering increased efficiency and process control.
