Flue gas condensation

Flue gas condensation has historically been Radscan’s strongest area, with over 50 unique projects on our reference list. The technology is based on a moist fuel (typically biofuel or waste) and a low-value energy recipient (typically district heating). The moisture in the fuel evaporates before the fuel is combusted, causing a loss of energy.

Our technology means that some of this energy can be recycled and used in the district heating network. Using this technology, a typical energy yield from fuel can increase by about 25 %, meaning significant savings in the form of reduced fuel demand, as well as providing significant environmental benefits. Carbon dioxide emissions are reduced along with the fuel demand, and the flue gas emitted from the facility is treated in the process.


Condensate treatment

Traditionally, flue gas condensate was purged using flocculation/precipitation and sand & carbon filters. We used this technology until 2005, when we installed our last traditional treatment plant. Since then, we use membrane technology, which provides significant benefits in terms of water quality but also energy and chemical savings.

But the biggest advantage is the flexibility. Our clients’ water treatment needs vary greatly and using this flexible technology we are able to meet all requirements. From the strictest requirements for the production of dilution water from flue gas condensate to the simplest cases where the only requirements are on particle content and pH value.

Flue gas treatment

In combination with flue gas condensation, flue gas treatment is a natural element. The method is chosen based on the process and treatment requirements, but also in consultation with the customer. The treatment is usually done wet in a scrubber or dry in a textile barrier filter using carbon & lime dosing.




Through our subsidiary Radscan Industriservice, we are happy to offer an after-sale customer relationship once the project is handed over. An increasing number of customers are seeing the benefits of letting Radscan’s experienced project managers and technicians handle the ongoing maintenance of their plants. Radscan sees this as a natural part of our total commitment to our customers and their plants.

Our concept of maintenance even goes a little beyond traditional maintenance. Changes in regulatory requirements and processing conditions necessitate upgrading and maintenance of the plants.  Typical assignments for our service organization include a preliminary study of such upgrades and implementation.
