QCVN 34:2010/BTNMT

NATIONAL TECHNICAL REGULATION
ON EMISSION OF REFINING AND PETROCHEMICAL INDUSTRY OF INORGANIC SUBSTANCES AND DUSTS

Forewords

QCVN 34:2010/BTNMT was compiled by the Drafting Board of the National Technical Regulation on air quality, submitted by the Vietnam Environment Administration, Department of Science and Technology and Department of Legal Affairs and promulgated under the Circular No. 42/2010/TT-BTNMT dated December 29, 2010 of the Minister of Natural Resources and Environment.

NATIONAL TECHNICAL REGULATION
ON EMISSION OF REFINING AND PETROCHEMICAL INDUSTRY OF INORGANIC SUBSTANCES AND DUSTS

1. GENERAL PROVISIONS

1.1. Scope of regulation

This Regulation specifies the maximum permissible value of dusts and inorganic substances in the emission of refining and petrochemical industry when being released into the air environment.

1.2. Subjects of application

This Regulation applies to organizations and individuals involved in emitting emission of refining and petrochemical industry into the air environment.

This Regulation does not apply to production sectors of refining and petrochemical facilities that already have separated technical regulations.

1.3. Interpretation of terms

In this Regulation, the terms below are construed as follows:

1.3.1. Emission of refining and petrochemical industry means a mixture of matters emitting from each stationary chimney of the refinery and petrochemical facility to the air environment.

1.3.2. Kp means the flow rate coefficient of the emission source corresponding to the emission flow of each chimney according to the design of the refinery and petrochemical facility.

1.3.3. Kv means the regional coefficient corresponding to the location of refinery and petrochemical facilities.

1.3.4. Standardized emission cubic meter (Nm³) means the cubic meter of emission at 250°C and absolute pressure at 760 mm of mercury.

2. TECHNICAL PROVISIONS

2.1. During the normal operation, the maximum permissible value of dusts and inorganic substances in the emission of refining and petrochemical industry is calculated according to the following formula:

Cmax = C x Kp x Kv

In which:

- Cmax means the maximum permissible value of dusts and inorganic substances in the emission of refining and petrochemical industry, weighted as milligram in standardized cubic meter of emission (mg/Nm³);

- C means the value of dusts and inorganic substances in the emission of refining and petrochemical industry as prescribed in Section 2.2;

- Kp means the flow rate coefficient of the emission source as prescribed in Section 2.3;

- Kp means the regional coefficient as prescribed in Section 2.4.

2.2. C value is used as a basis for calculating the maximum permissible value Cmax of dusts and inorganic substances in the emission of refining and petrochemical industry and specified in Table 1:

Table 1: C value of dusts and inorganic substances in the emission of refining and petrochemical industry

In which:

- Column A specifies the C value serving as a basis for calculating the maximum permissible value Cmax of pollutant parameters in emission of refinery and petrochemical facilities operated before the effective date of this Regulation.

- Column B specifies the C value serving as a basis for calculating the maximum permissible value Cmax of pollutant parameters in emission of newly established refinery and petrochemical facilities.

- In addition to 05 parameters specified in Table 1, depending on the environmental pollution management and control requirements and purposes, other pollutant parameters must comply with QCVN 19:2009/BTNMT – National Technical Regulation  Industrial Emission of Inorganic Substances and Dusts.

2.3. The flow rate coefficient of the emission source (Kp) of refinery and petrochemical facilities is determined to each chimney and specified in Table 2:

Table 2: Kp coefficient applicable to each chimney

2.4. The regional coefficient (Kv) corresponding to the location of refinery and petrochemical facilities is specified in Table 3:

Table 3: Regional coefficient (Kv)

3. DETERMINING METHODS

3.1. Methods used to determine value of pollutant parameters in emission of refining and petrochemical industry shall comply with the following National Standards:

- TCVN 5907:2005 – Stationary source emissions - Determination of concentration and mass flow rate of particulate material in gas-carrying ducts - Manual gravimetric method.

- TCVN 6750:2005 – Stationary source emissions - Determination of mass concentration of sulfur dioxide - Ion chromatography method;

- TCVN 7172:2002 – Stationary source emissions - Determination of the mass concentration of nitrogen oxides - Naphthylethylenediamine photometric method;

- TCVN 7242:2003 – Health care solid waste incinerators - Determination method of carbon monoxide (CO) concentration in fluegas.

3.2. The use of other determining methods under the national and international standards with equal or higher accuracy than the national standards mentioned in Section 3.1 is accepted.  When there are no national standards for the determination of parameters specified in this Regulation, other international standards shall be applied.

4. IMPLEMENTATION ORGANIZATION

4.1. Organizations and individuals involved in emitting emission of refining and petrochemical industry into the air environment shall comply with this Regulation.

Refining and petrochemical projects approved but have not come into operation before the effective date of this Regulation, shall follow the Decision on approval of the environmental impact assessment report.

4.2. State management agencies in charge of environment shall guide, check and supervise the implementation of this Regulation.

4.3. In case the National Technical Regulations and National Standards referred to in this Regulation are mended, supplemented or replaced, the new documents shall be applied.
