Dürr’s Environmental Technology


As the role of technology increases in our lives, it is leaving a negative impact on nature. Therefore, it is crucial to protect the environment by effectively cutting off emissions and minimizing resource consumption. Dürr, one of India’s leading Air Pollution Control System Providers, has taken significant steps in this regard. The company has pledged to save nature by using environment-friendly technologies and enhancing energy efficiency. These technologies are based on catalytic oxidation, absorption and adsorption, and thermal oxidation processes. In addition, Dürr helps its customers incorporate environmental legislation in their operating structure. Some of the key benefits offered by Durr includes:

  • An extensive portfolio of products
  • Consultancy for individual industries
  • More than 10,000 systems installed all over the world
  • Global support on site
  • Lifetime servicing

Dürr has combined technological expertise with a global presence to design and manufacture state-of-the-art systems. These systems help reduce energy consumption, guarantee highly certified processes, and efficiently dispose of exhaust gases and residues. The company aims to supply end-to-end solutions of exceptional quality from planning to implementation and servicing and enables its customers to realize substantial potential savings by using new energy sources.

Exhaust gas and air pollution control

The environment is subjected to many dangers caused by human activities, including exhaust gases and vapors produced by manufacturing processes. Dürr has developed air pollution control systems to manage these issues. The primary objectives of Dürr Air Pollution Control Systems are:

  • Separating or extracting exhaust gases from reaction processes
  • Management of unpleasant odors
  • Obeying the official legal directives on emission controlwhile minimizing the use of primary energy
  • Purifying the exhaust air from manufacturing processes

To protect the natural ecosystem, exhaust vapors and gases have to be removed from the exhaust air before releasing it into the atmosphere.

Air pollution control with different processes

The Air Pollution Control Systems built by Dürrare based on the separation process. These systems extract solid particles, such as dust, from waste air. Depending on the physical and chemical properties of the substances, a broad spectrum of processes is available for separating liquid and gaseous contaminants from waste air. Therefore, to fulfill every customer’s requirement, Dürr has an Air Pollution Control solution.

Catalytic processes are another choice for the management of air pollution. These processes include the combustion of pollutants. Due to the catalyst, the required temperatures are lower than those in purely thermal processes. The pollutants are heated to a high temperature so that they turn into non-hazardous substances.

Another alternative for control of air pollution is sorptive processes. A sorptive process concentrates the contaminants (adsorption) or removes them from the exhaust air through absorption.

Dürr offers both dry and wet solutions for controlling multi-pollutant emissions in a single train for:

  • Furans and Dioxins
  • Acid Mists
  • Odor Control
  • NOx
  • Acid Gases, SO2
  • Particulate
  • HAPs, VOCs, CO
  • Temperature and Humidity Control
  • Solvent Recovery
  • Wastewater Treatment

The commercially-proven solvent purification and industrial air pollution control technologies from Dürrinclude:

  • Dry Electrostatic Precipitators
  • Wet Scrubbers
  • Distillation, Separation and Purification Systems
  • Wet Electrostatic Precipitators
  • Oxidizers (Thermal, Catalytic)
  • Evaporative Gas Cooling and Conditioning
  • Spray Dryer Absorbers
  • SCR and SNCR NOx Control Solutions
  • Solvent Recovery Systems

Control of air pollution is necessary for nature to survive. Therefore, Dürr is consistently undertaking steps to protect the environment and ensure that their manufacturing or operating activities don’t cause ecological imbalance.
