National Technical Regulation QCVN 34:2010/BTNMT for Emission of refining and petrochemical industry of inorganic substances and dust
Foreword
The QCVN 34:2010/BTNMT is compiled by the Drafting Board of National Technical Regulation on Air Quality, approved by the Vietnam Environment Administration, Department of Science and Technology, and Department of Legal Affairs, and promulgated under Circular No. 42/2010/TT-BTNMT dated December 29, 2019 of the Minister of Natural Resources and Environment.
NATIONAL TECHNICAL REGULATION ON EMISSION OF REFINING AND PETROCHEMICAL INDUSTRY OF INORGANIC SUBSTANCES AND DUSTS
1.1. Scope
This Regulation prescribes maximum permissible value of dust and inorganic substances in emission of refining and petrochemical industry released into the air.
1.2. Regulated entities
This Regulation applies to organizations and individuals relevant to the release of emission of refining and petrochemical industry into the air.
This Regulation shall not be applied to fields of manufacturing within petrochemical refineries that have had their own regulations.
1.3. Definitions
In this Regulation, the terms below are construed as follows:
1.3.1. emission of refining and petrochemical industry means a mixture of matters released from each fixed smokestack of petrochemical refineries into the air.
1.3.2. Kp means emission source coefficient corresponding to emission flow of each smokestack by design of petrochemical refineries.
1.3.3. Kv means zone, area coefficient corresponding to where petrochemical refineries are located.
1.3.4. normal cubic meter of emission (Nm3) means a cubic meter of emission at 25 oC and atmospheric pressure of 760 mm of mercury.
2.1. During normal operation, maximum permissible value of dusts and inorganic substances in emission of refining and petrochemical industry shall be calculated as follows:
Cmax = C x Kp x Kv
Where:
- Cmax means the maximum permissible value of dusts and inorganic substances in emission of refining and petrochemical industry, in milligram per normal cubic meter of emission (mg/Nm3);
- C means value of dusts and inorganic substances in emission of refining and petrochemical industry according to 2.2;
- Kp means emission source coefficient according to 2.3;
- Kv means zone, area coefficient according to 2.4.
2.2. C serves as the basis for calculating Cmax of dusts and inorganic substances in emission of refining and petrochemical industry and is specified under Schedule 1:

Where:
- Column A dictates C value which serves as the basis for calculating Cmax of pollution indices in emission of petrochemical refineries operating before the effective date hereof.
- Column B dictates C value which serves as the basis for calculating Cmax of pollution indices in emission of new built petrochemical refineries.
- In addition to 5 parameters under Schedule 1, depending on the requirements and purpose of environmental pollution management and control, other pollution indices shall conform to the QCVN 19:2009/BTNMT.
2.3. Kp of petrochemical refineries shall be calculated for each smokestack and specified under Schedule 2:
