About mercury removal and dioxin removal in package units.

Dioxin and/or Mercury Removal

in Package Units

Technical information

Götaverken Miljö offers standardized gas treatment package unit supplies based on

our unique technologies ADIOX ® for dioxin removal and/or MercOx for mercury

removal. The units are compact and designed for minimum on site erection works.

Advantages are high performance, high availability, low maintenance require-

ment, flexible layout, low total cost and a minimum of residues as the packing

material is incinerated after use, also destroying the captured dioxins.

Performance and design: The required removal efficiency of the units, for each specific pollutant, are design parameters that

will define the overall dimensions and number of stages. Normally the units are designed to meet the EU waste incineration.

Typical supply package:

• Basic process design of absorber or scrubber system. For wet scrubbers, process water circulation systems and

possibly related subsystems, such as water treatment systems, may be included.

• Detailed design of absorber or scrubber.

• Material supply of scrubber or absorber including Adiox tower packing and Adiox droplet separators.
