Compliance-Überblick

Dieser Überblick ist derzeit nur auf Englisch verfügbar.

Geltungsbereich und Anwendbarkeit

This standard applies to the calculation and assessment of energy consumption in the production of prebaked anodes, graphitic cathode carbon blocks, graphitized cathode carbon blocks, and cathode pastes for aluminum electrolysis. It is also applicable to the control of energy consumption for new, reconstructed, and expanded projects of these carbonaceous material production facilities. Manufacturers must ensure their products meet these energy consumption limits to access the Chinese market. It does not apply to carbonaceous materials not used in aluminum production.

Technische Anforderungen

GB 25324-2022 establishes energy consumption limit grades, technical requirements, statistical scopes, and calculation methods for unit product production of carbonaceous materials used in aluminum production. It classifies energy consumption limits into three grades: Grade 1 (lowest energy consumption), Grade 2, and Grade 3. For existing facilities, the energy consumption limit value for unit products shall not be greater than the Grade 3 limits. Existing enterprises must meet the Grade 3 requirements to maintain compliant operations. For new, reconstructed, and expanded projects, the energy consumption access value shall not be greater than the Grade 2 limits, ensuring new infrastructure meets higher energy efficiency standards. The standard specifies limits for specific production processes, such as calcination, molding, baking, and assembly for prebaked anodes. It also covers specific process requirements for graphitic and graphitized cathode carbon blocks, as well as cathode pastes. The calculation methodologies reference standards like GB/T 2589 and GB/T 12723 to ensure accurate energy accounting.

Prüfverfahren

The standard outlines detailed statistical scopes and calculation methods to determine the comprehensive energy consumption of each production process. It requires the conversion of all energy consumption into standard coal equivalent (kgce/t) using specific formulas. Enterprises must accurately calculate their unit product energy consumption using the specified formulas for each process. Reference coefficients for converting various energy types and energy-consuming working fluids to standard coal are provided in the appendices, such as Appendix E and Appendix F. Energy metering must comply with the provisions of GB 17167.

Häufige Fragen

What products are regulated under GB 25324-2022?

It regulates prebaked anodes, graphitic cathode carbon blocks, graphitized cathode carbon blocks, and cathode pastes used in aluminum electrolysis.

Are there any updates from the previous version of GB 25324-2022?

Yes, it replaces GB 25324-2014 and GB 25325-2014. The main changes include restructuring the energy consumption limits into Grade 1, 2, and 3, and adding energy consumption limit grades for graphitized cathode carbon blocks and cathode pastes.

What are the requirements for new manufacturing facilities under this standard?

New, reconstructed, and expanded projects must meet the Grade 2 energy consumption access values, which are stricter than the Grade 3 limits required for existing facilities.
