ENA Energy Power Plant,
Enköping - Sweden

At Kraftvärmeverket in Enköping, ENA Energi AB, heat from the flue gases is recovered via a flue gas condenser.

The existing system at the plant will not be able to meet future requirements for the degree of purity of outgoing flue gas condensate.
Ena Energi AB will therefore supplement and rebuild existing condensate training to enable the following:

Water recovery for use in the steam / water cycle at the CHP plant

Reuse of water, if necessary, for filling district heating networks
Adequate purity of the water discharged to the recipient, also for future environmental requirements

The customer wants columns to clean outgoing condensate from dissolved impurities such as heavy metals.
