Air emission treatment consulting
Nanoen surveys dust and gas emission sources in your plant, assesses any existing system and compares treatment options on performance, capital and operating cost, so you can choose the right solution before construction starts.
- Emission source survey
- Technology options compared
- Capital and operating cost estimates
- Review of contractor proposals
Common challenges for businesses
If you are facing any of the situations below, Nanoen can help.
Many different sources
Dust, solvent vapour, boiler flue gas, odour: each source needs its own approach, and it is unclear whether to combine or separate them.
System not performing
Hoods do not capture all emissions, fans are overloaded and monitoring results are inconsistent.
Bids hard to compare
Quotations differ in technology, equipment and operating cost, making them difficult to evaluate.
Technical basis for dossiers
EIA reports and environmental permits require a description of the emission control works and expected performance.
Who this service is for
- Investors in new projects with boilers, dryers or dusty processes
- Plants whose emission control system is non-compliant or unstable
- Companies needing an independent review of contractor proposals
- Facilities facing odour or dust complaints, or preparing for monitoring and inspection
Serving businesses in Hanoi, Bac Ninh, Hung Yen, Hai Phong, Ninh Binh, Phu Tho and neighbouring provinces.
Scope of work
- Survey of production lines to identify dust, gas and odour sources
- Assessment of existing hoods, ductwork, fans and treatment equipment
- Comparison of technologies: bag filters, cyclones, scrubbers, activated carbon adsorption…
- Estimates of capital cost, power, chemicals and consumables
- Design basis and specifications against current national standards (QCVN 19, QCVN 20)

Frequently asked questions
When should we hire a consultant instead of ordering construction straight away?
When the plant has several emission sources, a complex gas composition, or you have received different proposals and are unsure which to choose. Consulting defines the problem correctly first and reduces the risk of investing in the wrong technology.
Does Nanoen measure emissions during consulting?
Nanoen surveys the site and uses existing monitoring results. Where more data is needed, Nanoen works with a licensed monitoring organisation to carry out sampling and measurement.
Can you review another contractor's design?
Yes. Nanoen reviews extraction flow, fan selection, treatment equipment, consumables and operating cost in the contractor proposal, and lists points to clarify before you sign.
Which standards apply to industrial emissions?
Typically QCVN 19 (dust and inorganic substances) and QCVN 20 (certain organic substances), plus any sector-specific standards. The applicable standards and limit values depend on the type of production and the facility's environmental permit.
