Thermal oil boiler for liquid waste streams

What happens to the liquid waste streams your processes generate? All too often, these streams are discharged or treated as waste, even though they still hold significant energy value.

With a thermal oil boiler that runs on liquid waste streams, you can convert that energy into usable process heat. In doing so, you get to lower your consumption of primary fuels, to boost your site’s energy efficiency, and to capitalize on your existing process streams.

The Callens Group specialists design installations that turn liquid waste streams into high-temperature process heat safely, reliably, and efficiently.

When does a thermal oil boiler for liquid waste streams make sense?

Not all liquid waste streams are waste. In many production environments, these side streams still contain a considerable amount of usable energy. When that is the case, they can be an attractive alternative to natural gas or other fossil fuels you are currently generating process heat with— for example, in a thermal oil boiler.

Businesses that have a continuous supply of energy-rich liquids stand to benefit the most, significantly lowering their energy costs while raising their energy efficiency.

Reasons to use liquid waste streams for process heat:

  • You have liquid waste streams with an energy value.
  • You want to limit the disposal costs of waste streams.
  • You want to consume fewer fossil fuels.
  • You need continuous process heat at a high temperature.
  • You want to increase the energy efficiency of your site.

Technical specifications of thermal oil boilers for liquid waste streams

Every liquid waste stream has its own characteristics. That is why each installation is designed around the specific viscosity, calorific value, composition, storage requirements, and availability of the waste stream at hand.

That is also the reason why our engineers begin every project with a thorough analysis of these parameters. It allows them to determine which burner, storage, and combustion technology best suits your application.

BENEFITS

Benefits of a thermal oil boiler for liquid waste streams

Far too often, the waste streams of a production process are labeled as a cost, when in fact they can be a valuable source of energy. A thermal oil boiler makes it possible to efficiently convert the energy in those waste streams into industrial process heat.

Valorization of waste streams

Liquid by-products and waste streams find a useful purpose within your own production environment.

Fewer fossil fuels

Using waste streams as fuel reduces the need for natural gas or other primary energy sources.

Less waste

By harnessing the energy content of waste streams, disposal and processing costs often drop as well.

Lower energy costs

By valorizing the waste streams from your own processes, you need to buy in less energy.

Higher energy efficiency

The available energy stays within the production process instead of going to waste.

High process temperatures

Temperatures of up to around 300 °C are possible without high system pressures.

How do you integrate a thermal oil boiler for liquid waste streams into your existing infrastructure?

Integration starts with an analysis of the available waste streams and the heat demand of your production process. Next, we look at how the boiler can be connected to existing thermal oil consumers and which storage and treatment systems are required.

Depending on your reliability requirements, the installation can run entirely on waste streams or be combined with a second fuel.

FAQ

Questions? We have the answers.

That will depend on the energy value and composition of your waste stream. Examples include waste oils, contaminated solvents, organic process residues, distillation residues, and other liquid side streams released during industrial processes. Every waste stream is analyzed in advance to determine whether it is technically and economically suitable as a fuel to generate process heat.

Yes. With proper engineering and fuel treatment, this technology offers the same operational reliability as other industrial thermal oil boilers.

This technology is used above all in sectors where liquid process residues are released, such as the chemical industry, the food industry, the pharmaceutical sector, waste processing, and certain process industries. For companies that have a continuous supply of energy-rich waste streams, it can be an attractive way to increase their energy efficiency.

As an EPCS integrator, the Callens Group takes on the entire process: from on-site analysis and engineering to installation and service. That gives you a single point of contact throughout the full lifespan of your thermal oil boiler for liquid waste streams. You can find more about the different steps in our workflow here.
