Liquid Blending and Batching

Blending auto
Blending module feeds one ingredient in proportion into the flow of a master stream.
ChemIndustrial’s liquid blending systems combine process fluids, in closed pipework, into a single output stream to satisfy your in-line blending requirements.
Are you BLENDING or BATCHING?
In fluid processing, the term “BLENDING” refers to the combining of two or more process fluids, in-line, into a single output stream. Usually, but not always, blending is done as a continuous process in closed pipework.
On the other hand, “BATCHING” is the accumulation of controlled quantities of one or more process materials into one or more vessels. Visit CHEMINDUSTRIAL BATCHING SYSTEMS to learn more about our batching system capabilities.

Simple blending systems

ChemIndustrial builds complete skid-mounted blending systems to satisfy a wide range of customer requirements. Each system uses a customized combination of ChemIndustrial’s innovative liquid handling methods to achieve the intended blending purpose.

Some of these innovative techniques use centrifugal pumps to perform volumetric metering tasks that would otherwise require piston or diaphragm pumps. The high reliability and low cost of centrifugal pump-based flow metering systems often make these a better choice than traditional positive displacement pumps for the blending systems we design. But we readily use positive displacement pumps where they are clearly the most appropriate devices for a particular blending task.

Some ChemIndustrial blending systems use simple mechanical devices such as venturis, self-acting pressure controllers and in-line flow control devices. ChemIndustrial can often satisfy a customer’s blending requirements with systems like this without needing electronic controls. Some of these systems take advantage of existing flow sources to avoid the need to install any prime mover within the blending system.

More elaborate blending system configurations

ChemIndustrial builds blending systems as skid-mounted modules. The modules for relatively small blending systems are built in stainless steel frames that look similar to portable generator frames.

Typically, one blending module handles 1 or 2 streams and includes sensors, pumps, valves and control elements. If the system has more blend streams, we add more modules. This modular approach allows easy scale-up and retrofitting of blending systems to any level of size and complexity.

Usually, all modules are installed together as a central blending station. Alternatively, our modular approach allows blending skids to be distributed throughout the customer’s plant.

If the system is controller-based, ChemIndustrial provides an intelligent blend controller on each skidded module. Multiple blend modules are coordinated via a control network that unifies all of the individual blend controllers into a single system. Monitoring nodes can be added to the network for control room or other remote service.

Special-purpose blending systems

Over the years we have tackled some unusual blending system requirements. Some of these:

  • Time-proportional blending systems
  • Gasoline engine-powered blending systems
  • Diesel engine-powered blending systems
  • Trailer-mounted blending systems

We have designed any number of configurations to satisfy the multitude of special blending problems presented by customers for industrial, lab and agricultural projects.

Controller-based blending systems

Pumps, valves and in-line mixing elements can be controlled using electronic flowmeters, flow controllers and PLCs.

Other blending system elements

ChemIndustrial also configures and supplies the additional process parts and pieces needed for a complete blending system. We supply mix tanks as well as ingredient tanks, surge tanks and finished product vessels. We also design and build ingredient valve manifolds for the inlet side of blending systems and distribution manifolds for the outlet side.

Working with ChemIndustrial

When competent specialist suppliers such as ChemIndustrial are available, you can avoid the cost and time needed to write detailed equipment and control specifications. Instead, you can allow us to adapt our technology to your specific situation. This reduces your project costs and decreases the time needed to quote and accomplish your projects. Since most experts agree that there is little evidence that better systems result from the customer effort spent preparing detailed specs, it makes sense for you to leverage ChemIndustrial’s blending capabilities.
