Flue gas scrubbers, gas scrubbers and condensate treatment

Flue gas cleaning and condensation

Ehox designs and supplies flue gas scrubbers that combine gas cleaning and heat recovery in one process. In the scrubber, flue gas comes into contact with the scrubbing liquid, which captures impurities.

During heat recovery, the flue gas is cooled. When water vapour in the gas condenses, heat is released and recovered. The heat is transferred to a suitable system, such as process water, a district heating network or another process that can use it.

In practice, heat recovery scrubbers almost always also remove sulphur and chlorine compounds from the flue gas. The process, equipment and materials are selected according to the gas characteristics, treatment objectives and operating conditions.

Combustion air humidification and heat pump integration

Heat recovered at the flue gas scrubber can be used to humidify combustion air. The added water vapour increases the moisture content of the flue gas and the amount of latent heat available for recovery.

Heat recovery can also be designed for integration with a heat pump, allowing heat to be used at a temperature level suited to the plant.

Condensate treatment as part of the solution

Flue gas condensate treatment is designed as part of the overall heat recovery solution. Ehox supplies the process and equipment needed to purify the condensate.

Design and delivery

Ehox designs gas treatment solutions based on process data and the desired outcome. A delivery can include process design, equipment and systems, installation supervision and commissioning. The scope, interfaces and responsibilities are agreed with the customer.

New and existing plants

We provide solutions for both new plants and existing installations. For modifications, we take existing processes and equipment interfaces into account.

Partner network and delivery area

We work with a broad partner network. Deliveries focus on Europe, particularly Northern Europe.

Commissioning and lifecycle services

During commissioning, we review the equipment operation and operating instructions with the customer so the system can become part of the plant's process smoothly.

We also inspect equipment in operation, troubleshoot issues and carry out upgrades. Maintenance and service are agreed according to each site's needs.
