Industrial emission regulation QCVN 19: 2009/BTNMT

What is industrial emission regulation QCVN 19: 2009/BTNMT

Industrial Emissions Regulation QCVN 19: 2009/BTNMT issued by the Ministry of Natural Resources and Environment in 2009, is a legal document regulating the maximum allowable limit of pollution parameters in industrial emissions when discharged into the environment. This is the legal basis for controlling air pollution caused by industrial production activities.
Scope of application
This Regulation applies to emissions from the following industrial waste sources when discharged into the environment:
  • Boilers, burners of solid, liquid, gas fuels.
  • Non-ferrous and metal smelting furnaces.
  • Cement, lime and other minerals.
  • Basic chemicals.
  • Paper production.
  • Dyed textiles.
  • Food processing industry.
  • Construction material manufacturing industry.

QCVN 19: 2009/BTNMT

The standard specifies the maximum allowable limits for pollution parameters in industrial exhaust gases such as dust, SO2, NOx, CO, VOC, H2S…
The parameters specified in the regulation include:
  • Dust: 100 – 200 mg/Nm3
  • SO2: 400 – 2000 mg/Nm3
  • NOx: 200 – 750 mg/Nm3
  • CO: 100 – 1200 mg/Nm3
  • H2S: 5 – 200 mg/Nm3

The method of determining the value of pollution parameters

The standard guides the methods of sampling, measurement and analysis of exhaust gas samples to determine the concentration of pollution parameters. The methods recommended for use include:
  • Emission sampling: TCVN 5937: 1995
  • Dust determination: TCVN 5938: 1995
  • SO2 Determination: TCVN 5067: 1995
  • Determination of NOx: TCVN 6137: 1996
  • Determination of CO: TCVN 5972: 1995
Table of values of pollution parameters
The standard specifies the maximum allowable limits for each type of industrial production. The specific values are specified in the tables attached to the standard.
For example:
  • Coal-fired power plants: Dust – 100 mg/Nm3; SO2 – 850 mg/Nm3; NOx – 750 mg/Nm3.
  • Cement: Dust – 100 mg/Nm3; SO2 – 400 mg/Nm3; NOx – 1200 mg/Nm3.
  • Basic chemicals: Dust – 50 mg/Nm3; SO2 – 200 mg/Nm3; NOx – 300 mg/Nm3.
The meaning of the standard
  • Protect the air environment, limit air pollution from industrial production activities.
  • This is the legal basis for state management agencies to inspect and monitor the exhaust activities of production facilities.
  • As a basis for businesses to perfect technology, apply standard emission treatment measures.

Subjects must comply with industrial emissions regulations

Subjects that must comply with the standard include:
  • Production, business and service facilities with industrial emission generation activities.
  • State management agencies are involved in the field of environmental protection.
  • Owner of projects to invest, renovate and expand industrial production facilities.
Thus, industrial emission regulation QCVN 19: 2009/BTNMT plays a very important role in the protection of the air environment, contributing to reducing the impact of air pollution on public health and the living environment.
Compliance with industrial emissions regulations is a necessary job to help businesses and factories operate stably, avoid unnecessary problems related to environmental protection.
