Exhaust Gas Streams
The term exhaust gas stream is used for air or gas streams, loaded with hazardous components, that are expelled into open air.
Exhaust gas streams can be found in many industrial applications:
- chemical processes
- the use of solvents
- combustion processes
- the use of glues
- the use of hazardous gases
Environmental Legislation
Emission of these gas streams is subject to strict air pollution standards in more and more countries.
Accordingly, more companies adapt their production processes, so that they can meet the emission standards implied by international organisations and national law.
Exhaust Gas Scrubbing
The choice for a specific technology to treat these exhaust gas streams, depends on specific circumstances in the production process.
Gas Scrubbers
In reality, gas scrubbers are often preferred, in combination with other technologies where necessary.
One of the most important reasons is that gas scrubbing has a long history of reliabilty and safety.
Moreover, they can be used in vast and even exceptional circumstances, making them the solution of choice for most applications.
Advantages
- Gas scrubbers handle strongly fluctuating gas volumes and poluent concentrations
- They reach high efficiency coefficients
- Several hazardous componenents can be removed at the same time, even together with dust particles
- They can also be used for quenching of hot gas streams
