Design and Construction of Exhaust Gas and Dust Treatment Systems
Nanoen surveys emission sources, measures key parameters and designs dust and exhaust gas collection and treatment systems suited to each production stage, helping your plant meet standards and improve the working environment.
- Emission source survey and measurement
- Technology matched to gas and dust type
- Turnkey fabrication and installation
- Monitoring and Environmental Permit support

Common challenges for businesses
If you are facing any of the situations below, Nanoen can help.
Emissions exceeding standards
Stack monitoring results for dust and exhaust gas do not meet the applicable standards (QCVN).
Spreading odour and dust
Affects workers' health and draws complaints from surrounding residents.
Ineffective collection
Weak or leaking hoods, ductwork and extraction fans let gas and dust escape into the workshop.
New projects needing a permit
A compliant exhaust gas treatment system is required to be eligible for an Environmental Permit.

Frequently asked questions
Which exhaust gas treatment technology is right for my plant?
It depends on the type of dust or gas, temperature, flow rate and pollutant concentrations. Usually several stages are combined, for example a cyclone and bag filter for dust, an absorption scrubber for acid gases and activated carbon for solvent vapours. Nanoen makes a recommendation after surveying and measuring.
Do you build boiler exhaust gas treatment systems?
Yes. Nanoen designs boiler dust and exhaust gas treatment systems according to the fuel type and boiler capacity.
Will installation require a long production shutdown?
Most equipment is prefabricated, so machines only stop for a short time for tie-in. The construction schedule is agreed with the plant in advance.
Does the system need continuous automatic emission monitoring?
It depends on the exhaust gas flow rate and the type of production under current regulations. Nanoen reviews this and advises from the design stage.
