HUGO PETERSEN-gas cleaning

HUGO PETERSEN GmbH has over 70 years experience in industrial gas processing and -cleaning. Where, in the early days, the cleaning of SO2-containing waste gases for the production of sulphuric acid by the contact process, was the driving force.

At the beginning of the 1960's, gas cleaning was also a field of activity for HUGO PETERSEN outside of the manufacture of sulphuric acid.

Here again, gas cleaning began as a godfather to the manufacture of sulphuric acid.

In addition to the separation of acidic components from waste gases, aerosol separation was and still is a crucial technological component of the HP portfolio.



  • Nasse Gasreinigung
  • Trockene Gasreinigung
  • Aerosolabscheidung


  • Absorptiv
  • Adsorptive
  • Katalytisch
  • Mechanisch


  • Schwefelsäure und Oleum
  • SO3 und SO2 als Gas oder flüssig
  • CaSO4, NaSulfite, Na2SO4 (NH4)2SO4
  • HCI und andere

The HP technology is initially divided into three main groups:

  • Wet gas cleaning
  • Dry gas cleaning
  • Catalytic gas cleaning
  • Aerosol separation

The express goal of a gas cleaning concept is the optimal combination of different technologies.

In doing so targets, such as the following, apply:

  • Resource recovery
  • Energy conservation
  • Energy use

The following enumerations are intended to provide an overview, but are by no means complete.


Wet gas cleaning

Absorptive separation of gas components in the alkaline as well as partially in acidic mediums

Acid gas components such as

SO2, SO3, HCl, HF, and other acid gas components

Heavy metals such as

As. Hg, Se, Cd and others

Adsorptive separation of gas components and/or particulate compounds

Acid gas components such as

SO2, SO3, HCl, HF, and other acid gas components

Heavy metals such as

As. Hg, Se, Cd and others

Organic compounds such as:

Dioxins, furans, PCBs, HCB and others

Catalytic decomposition and/or implementation of

SO2, NOX, N2O, dioxins, furans, PCBs, HCB and others as well as CO

Aerosol and super fine dust separation of

Acidic liquid aerosols, organic aerosols as well as particulate matter

By means of:

  • static centrifugal separators
  • dynamic / rotating centrifugal separators
  • electrostatic precipitators

Resource recovery

From the separated components, other materials are also produced like:

  • FGD gypsum for use
    - in the construction industry
    - as an aggregate for the production of ceramic and cement
    - etc.
  • Sodium sulphite solutions for use in the beverage industry
  • Mg-sulphite solutions
  • Ammonium sulphate
  • Hydrochloric acid
  • Sulphuric acid
  • Oleum
  • SO2-rich gases
  • SO2-liquid
  • SO3-gas
  • SO3-liquid
