T/ZGXX 0002-2018 Synthetic detergent industry atmospheric pollutant emission standard

Scope

Scope: This standard specifies the requirements for air pollutant emission control, monitoring, and supervision and management in the production of synthetic detergents using high-tower spraying technology. This standard applies to the air pollutant emission management of the high-tower spraying process in synthetic detergent production, as well as the environmental impact assessment, environmental protection facility design, completion environmental protection acceptance, and issuance of pollutant discharge permits for industrial construction projects of synthetic detergents, and the management of air pollutant emissions after their commissioning; Main technical content: 4. Air pollutant emission control requirements 4.1 Air pollutant emission limits 4.1.1 Air pollutant emission limits for enterprises in the synthetic detergent industry are divided into two levels; Level 1 applies to general areas, and Level 2 applies to key air pollution prevention and control areas; see Table 1. Table 1: Air pollutant emission limit units: (mg/m3) Emission level Production process Equipment Emission concentration limits Pollutant Emission monitoring location Particulate matter Sulfur dioxide Nitrogen oxides Level 1 High-tower spraying Spraying tower 80 80 150 Exhaust stack or pipeline Gas lift aging separator 50 — Level 2 High-tower spraying Spraying tower 50 50 100 Gas lift aging separator 50 — 4.1.2 It is recommended that enterprises in key areas implement Level 2 limits, and enterprises in other areas are recommended to implement Level 1 limits. The geographical scope and time period for implementing Level 2 limits shall be determined by the competent ecological and environmental departments under the State Council or provincial people's governments. 4.2 Requirements for exhaust stack height 4.2.1 The height of the exhaust stack shall not be less than 15m, and the specific height and distance from surroundin
