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.
